Workshop on Community Projects in Volcanology

Posted on September 10, 2018 by GeoPRISMS

Summary: Two-day U.S. National Science Foundation supported workshop focused on interdisciplinary community volcano experiments

Purpose: Continued advancement in fundamental geoscience demands substantial and coordinated investment in new observational scales and integrative approaches. As a result, community projects with open-access data and software have seen increasing use among the U.S. National Science Foundation geoscience community. In parallel, recent community reports on volcanology and subduction zone processes (ERUPT, SZ4D, USGS) highlight many challenges and opportunities in volcano science that demand increased community coordination. However, volcano science has seen relatively limited use of the community project mechanism, making this inherently interdisciplinary field particularly well-poised for rapid advance if new initiatives are developed.

To address these aims this NSF-supported workshop will gather members of the broad volcanology community to identify the most pressing questions that are best addressed through community projects and explore the merits of different models for community projects. Discussion and synthesis of recommendations for community projects will span strategies for coordinated multidisciplinary observations, effective incorporation of education and training opportunities, and development of community frameworks to foster integrative volcanology research. The workshop will include plenary sessions to motivate and focus discussions, goal-oriented breakout group discussions, lightning talks, and poster presentations. As the specific agenda becomes available the workshop info website will be updated.

Opportunities for remote participation will include: 1) Submission of white papers prior to the workshop. The program committee will make the white papers openly available online and use them to help shape topics/goals for specific discussion session at the workshop. White paper submission will be through the registration website. 2) Web-based remote viewing of the plenary presentations and lightning talks at the workshop.

Dates: November 28-29 (full days) and 30 (half-day), 2018

Location: DoubleTree Hotel, Downtown Albuquerque, NM

Support: Travel support is available for about 50 U.S. participants. Applications for travel support are due by September 24th, 2018. Applicants will be notified of their travel support status by October 8th. Travel support will include up to $500 for air & ground transportation and up to 3 nights of accommodations at the hotel hosting the workshop. Willingness to share double rooms is encouraged to maximize the number of supported participants.

Un-supported participants: Individuals seeking to participate without travel support must still register by October 15th. The number of unsupported participants will be capped based on space limitations at the meeting facility. Un-supported participants are eligible for the group rate for hotel rooms ($114 per night including breakfast) and will be charged a $60 registration fee to contribute to facility rental costs and on-site meals during the workshop.

V001. Accessorize it! Controls on the mobility of trace elements during subduction

Session ID: 52849

Conveners: Alicia Cruz-Uribe (University of Maine), Maureen Feineman (Penn State)

Session Description: Accessory phases of all types provide key tools for quantifying the trace element geochemistry, stable and radiogenic isotope geochemistry, geochronology, and phase equilibria of rocks in subduction zones. The mobility of traditional accessory phases such as zircon, rutile, titanite, monazite, allanite, and apatite, and perhaps of less studied accessory phases such as sulfides, halides, and oxides, provides a framework for interpreting trace element budgets and elemental fractionation in subduction zones, including volatiles and heat-producing elements. We invite contributions from all aspects of accessory phase geochemistry and petrology related to subduction, from the slab to the arc. We particularly invite studies linking one or more aspects of the subduction factory.

Confirmed Invited Speakers: Dustin Trail (Syracuse University)

MR003. Connecting Rheology, Microstructure, and Chemistry of the Upper Mantle: New Constraints from Experiments, Models, and Natural Observations

Session ID: 46785

Conveners: Yuval Boneh (Brown), Emily Chin (Scripps Institution of Oceanography, UC San Diego), Katharina Marquardt (Bayerisches Geoinstitut)

Session Description: Together, the rigid lithospheric lid and underlying weak asthenosphere comprise the Earth’s upper mantle. Several features, imaged geophysically and constrained from xenoliths/exhumed mantle sections, characterize the upper mantle. These include complex mantle kinematics (e.g., flow around subduction-zones), enigmatic discontinuities (mid-lithospheric and lithosphere-asthenosphere discontinuities), as well as the cratons stability paradox (long-lived stability with evidence for deformation). These phenomena can be explained through evolution in microstructure (e.g., grain-size, crystallographic preferred orientation), the chemical environment (e.g., water content, chemistry, and structure of grain-boundaries), and/or the existence of melt. In this session, we explore the effect of microstructure and chemistry and their relationships with the strength, deformation mechanisms and tectonic history of the upper mantle. We invite abstracts from a variety of scientific ventures, e.g., rock deformation experiments, analysis of natural samples, and numerical models, to shed light on the microstructural and chemical effect on upper mantle strength and tectonic evolution.

Confirmed invited speakers: Jessica Warren (U of Delaware), Nick Dygert (U of Tennessee)

ED001. 3D Printing in Earth and Planetary Science Education and Outreach

Session ID: 48843

Conveners: Christodoulos Kyriakopoulos (University of California Riverside), Gary B. Glesener (Virginia Polytechnic Institute and State University)

Session Description: 3D printing is a cutting-edge technology that holds tremendous promise for scientific research and education. For Earth and planetary scientists, the advantages of using such technology includes the ability to elucidate spatially complex geological structures and processes that are otherwise difficult to visualize using 2D media such as computer screens or paper. Concepts around earthquake faults, volcanoes, and trilobites often become more approachable for non-experts when 3D printed because they can be handheld and sometimes physically manipulated. The generation of 3D printed models, including experimental Lab samples (e.g. synthetic rocks), is not only a way to create hands-on educational activities, but a powerful tool to present our data and numerical models to a broader audience. This session focuses on 3D printing techniques and examples of 3D printed models used to enhance educational experiences. Presentations that focus on 3D printing technology, pedagogy, or both are welcome.

DI009. Dynamic Connectors: How Boundary Layers Shape the Evolution of the Earth’s Deep Interior

Session ID: 52478

Conveners: Keely Anne O’Farrell (University of Kentucky), Tobias Rolf (University of Oslo), Mingming Li (Arizona State University)

Session Description: Mantle dynamics at different scales are influenced by boundary layer processes. The upper boundary affects subduction processes and driving of plate tectonics. The bottom boundary controls plume generation and is dynamically linked to deep thermochemical features, such as LLSVPs and ULVZs. Plumes rising from the bottom boundary layer sample the whole mantle and place their signature on Earth’s surface, providing insight into mixing of chemical heterogeneities and the state of the deep mantle. The two boundary layers connect Earth’s surface, core and mantle interior and govern their interaction. Understanding the dynamics in the boundary layers will help to link shallow and deep mantle processes.This session will explore the dynamics of boundary layers, including generation of subduction zones, plate tectonics, mantle plumes, and heat transfer, and the resultant surface observations that provide useful constraints. We welcome theoretical, experimental, and observational contributions from geodynamics, seismology, geomagnetism, mineral physics, petrology, and other disciplines.

Confirmed invited speaker: Andy Biggin, University of Liverpool

T026. Linking Tectonic Geomorphology and Plate Boundary Processes in Terrestrial and Marine Environments

Session ID: 48541

Conveners: Jenna C Hill (USGS Pacific Coastal and Marine Science Center Santa Cruz), Janet Tilden Watt (USGS Pacific Coastal and Marine Science Center Santa Cruz), Daniel S Brothers (USGS Pacific Coastal and Marine Science Center Santa Cruz), Jared Kluesner (USGS Pacific Coastal and Marine Science Center Santa Cruz)

Session Description: Spatial variation in the crustal structure, kinematics, and seismogenic behavior of plate boundaries is often expressed in tectonic geomorphology and shallow structure both onshore and offshore. In this session, we aim to explore the relationship between surficial geomorphology, sediment dynamics and active tectonics to plate boundary processes, including studies that link upper plate processes to deeper crustal structure or hazards that are often associated with large earthquakes (e.g., landslides, tsunamis). We invite contributions from both marine and terrestrial environments, particularly those that employ new tools and advanced techniques for characterizing and quantifying spatial variability in deformation mode, rate, and recurrence. As it is particularly important to consider studies that span major geomorphic process domains (i.e. from the shoreline to the base of the slope), we encourage contributions from a wide range of geographic areas that employ a variety of methods to examine plate boundary processes and segmentation.

Invited Speakers: invited speakers include Dr. Olaf Zielke (KAUST) and Dr. Luca Malatesta (UCSC), with a range of expertise from earthquake seismology to coupled tectonic-surface processes and geomorphology.

T029. Multiscale imaging of plate boundary fault systems: integrating geophysical and geological data

Session ID: 50206

Conveners: Valerie Sahakian (University of Oregon), Maureen Walton (USGS), Anne Tréhu (Oregon State University), Estelle Chaussard (SUNY Buffalo)

Session Description: In the half century since the advent of the plate tectonics paradigm, we have gained remarkable insights into the underlying physics of plate boundary systems from substantial increases in observational data and modeling results. Moving forward, the integration of these data is essential for a holistic view of tectonic processes and the natural hazards posed by plate boundaries. We hope to attract new research from different fields to emphasize the importance of multiscale data integration, including geophysical studies of seismicity, geodetic observations, source inversions, structural models, and numerical modeling, as well as geologic studies of surface processes, geochemical and laboratory analyses, and paleoseismic observations. We especially encourage multidisciplinary contributions that emphasize multiscale data integration, but also welcome focused studies of observations, methodologies, and/or modeling that aim to improve our understanding of plate boundary systems from the Earth’s surface through the lithosphere, and their relevance to natural hazards and society.

Invited speakers: Tim Wright (University of Leeds), Dan Bassett (GNS Science)

T031. Observations and models of multiphase deformation in rifts and rifted margins

Session ID: 45394

Conveners: John Naliboff, Rebecca Bell, Scott Bennett, Jolante van Wijk

Session Description: Observations from rifts and rifted margins suggest continental extension commonly involves multiple phases of deformation with distinct structural, sedimentary and magmatic characteristics. In many rifts, deformation evolves both as a function of time and location, and rift architecture may reflect the influence of structural inheritance, evolution of the lithosphere’s thermal-mechanical profile, feedbacks between surface process and lithospheric deformation or large-scale changes in plate driving forces. Here, we solicit presentations that examine the long-term evolution of continental rift systems through field, geophysical and numerical investigations. In particular, we encourage submissions that focus on the processes driving changes in deformation style and use large 3-D observational or numerical data sets to characterize lithospheric deformation.

Invited Speakers: Donna Shillington (Columbia University), Robert Gawthorpe (University of Bergen)

T034. Puzzling Tectonics of the Gulf of Mexico: what do we know, what do we think we know, and what do we need to know?

Session ID: 49958

Conveners: Irina Filina (ifilina2@unl.edu), Erin K Beutel (beutele@cofc.edu), Patricia Persaud (ppersaud@lsu.edu) and Robert J Stern (rjstern@utdallas.edu)

Session Description: The tectonic history of the Gulf of Mexico is still being debated despite more than a century of petroleum exploration and an enormous amount of geophysical and geological data collected by industry. Tectonic models of the basin differ dramatically in key questions, such as the timing of opening, pre-breakup configuration of the crustal blocks and age of the seafloor. The proposed session intends to bring together researchers from different geoscience disciplines – geology, geophysics, geochemistry, tectonics, geodynamics – to discuss ways of improving our understanding of the basin. We welcome presentations on a broad range of topics – from addressing the continental break-up signature to those constraining sedimentation and hydrocarbon evolution. We also anticipate triggering active discussions on various aspects of Gulf of Mexico tectonics.

T041. Subduction Top to Bottom-2

Session ID: 43732

Conveners: David William Scholl (University of Alaska Fairbanks), Gray E Bebout (Lehigh University), Laura M Wallace (University of Texas at Austin)

Session Description: From top-to-bottom, many geological, geophysical, petrologic, geochemical and theoretical advances have been made in understanding the subduction zone processes and dynamics explored in 1996 in AGU Geophysical Monograph 96, “Subduction Top to Bottom”. This session, and a related Themed Issue in the online journal GEOSPHERE, are intended to revisit the topics explored 22 years ago in Monograph 96—reassessing them in light of new advances and discoveries in subduction zone research. We invite the broadest possible thematic range of contributions, including subduction-related hazards (volcanic eruptions, earthquakes and tsunamis) and resources.

T042. Subduction zone processes at the Hikurangi margin, New Zealand

Session ID: 44155

Conveners: Laura M Wallace (GNS Science, University of Texas Institute for Geophysics), Rebecca E Bell (Imperial College London), Kimihiro Mochizuki (University of Tokyo), Demian M Saffer (Pennsylvania State University)

Session Description: The Hikurangi subduction zone offshore New Zealandâs North Island exhibits pronounced along-strike changes in margin characteristics that make it an outstanding natural laboratory to investigate a wide range of fundamental subduction processes. This unique aspect of the subduction zone has sparked a plethora of new onshore and offshore geological and geophysical investigations. These experiments are helping to unravel the physical processes that control subduction plate boundary geodynamics and deformation. Recent efforts include scientific ocean drilling, multiple active and passive seismic experiments, seafloor geodetic deployments, and paleoseismic investigations. We welcome submissions that advance understanding of the Hikurangi subduction zone, including processes that underlie slow slip events and earthquake cycle behavior, volcanism and intra-arc rifting, volatile and fluid cycling, long-term subduction margin evolution, and geohazards associated with the plate boundary. Modeling studies, and comparative studies with other subduction zones to elucidate factors controlling subduction zone processes are also very welcome.

T043. Subduction Zone Processes, Orogenesis and Seismic Hazard: From the Alpine-Mediterranean to the Indo-Burma Region

Session ID: 47151

Conveners: Patricia Persaud (Louisiana State University), Francesca Di Luccio (INGV, Rome), Claudia Piromallo (INGV, Rome), Michael S Steckler (LDEO, Columbia University)

Session Description: This session aims to promote stimulating discussions on subduction zones and orogens and the evaluation of seismic hazard in these regions. The Alpine-Himalayan belt is characterized by several spatially limited, complex, highly heterogeneous and constantly evolving subduction zones in the Mediterranean. To the east, the structure and dynamics of the Indo-Burma subduction zone is quite poorly known. Revealing the dynamics of subduction systems along the Alpine-Himalayan orogenic belt is relevant to seismic hazard research due to the high population densities of these regions. We encourage authors to present novel data and innovative research based on multidisciplinary approaches. Research areas may include seismic imaging, surface and mantle processes, laboratory experiments and geodynamic modeling. We particularly encourage submissions that range from local to global scales, addressing any aspect of subduction-related and orogenic processes and their implications in subduction zones worldwide.

Invited Speakers: Anne Replumaz (Université Grenoble-Alpes), Eric Sandvol (University of Missouri)

Submissions from early-career scientists are strongly encouraged.

T044. Synthesis: Knowns and Unknowns of the Cascadia Subduction Zone

Session ID: 47390

Conveners: Helen Janiszewski (DTM, Carnegie Institution for Science), Wenyuan Fan (WHOI), Ikuko Wada (University of Minnesota), Caroline Seyler (McGill University)

Session Description: The Cascadia subduction zone is a global end-member warm-slab subduction zone and exhibits along-strike variations in subduction parameters (e.g., incoming plate age) and mechanical behavior (e.g., seismogenesis), serving as a unique natural laboratory to investigate a range of subduction zone processes, including tsunamigenic megathrust earthquakes, episodic tremor and slip, and arc volcanism. As these processes pose natural hazards, understanding their underlying causes is critical to natural hazard mitigation. The recent influx of offshore and onshore geophysical, geochemical, and geological data provides new opportunities to evaluate the entire Cascadia subduction zone in a coherent and consistent manner at various length and time scales. This session aims to synthesize recent findings and outstanding questions about this subduction system and the processes that occur within. We invite contributions from a wide range of disciplines, including (paleo)seismology, earthquake mechanics, geodesy, magnetotellurics, geochemistry, petrology, volcanology, structural geology, rock mechanics, and geodynamics.

Invited Speakers: Anne Pommier (UCSD), Amy Williamson (University of Oregon)

T051. The Varied Roles of Aqueous Fluids Near the Subduction Interface

Session ID: 47101

Conveners: Cailey B. Condit (MIT), Besim Dragovic (Boise State), Jonathan R. Delph (Rice University), Melodie E. French (Rice University)

Session Description: Along the subduction plate interface, water influences the rheological and geophysical properties as well as the rates and products of metamorphic reactions. Recent geologic and seismic studies demonstrate that strong feedbacks exist between the fluid-mediated chemical and petrologic evolution of the rock, deformation processes that control fault slip behavior, and geophysical signals we use to interpret physical conditions at depth. Fluid distribution and flux are thought to vary with depth and the permeability structure near the plate interface. These fluids are proposed to control episodic tremor-and-slip, dehydration-induced seismicity, serpentinization of the mantle wedge, overriding plate alteration, and the 4-D evolution in interface bulk-rock compositions, active deformation mechanisms, and rock strength. We invite contributions addressing the varied influence of aqueous fluids near the subduction interface from across the Earth science community including, but not limited to: experimental studies, geodynamics, petrology/geochemistry, structural geology, and geophysics.

Invited speakers: Roland Burgmann (UC-Berkeley) and Emily Cooperdock (WHOI)

T054. Whose Fault Is It? Relating Structural and Compositional Heterogeneity to Slip Behavior

Session ID: 49102

Conveners: Hannah Rabinowitz (Brown University), Helen Janiszewski (DTM), Samer Naif (LDEO), Ake Fagereng (Cardiff University)

Session Description: Large plate boundary fault systems are commonly rheologically segmented both along strike and down dip, including across the transition from seismic to aseismic shear displacement. In addition to thermal controls, these variations in slip style may arise due to geometric or compositional heterogeneities along the fault zone. Many questions remain on the relationships between structure and fault behavior. For example, how does rupture propagation interact with roughness or material properties along a fault at a range of slip rates? How does this impact the global variability in seismic behavior at plate boundaries? In this session, we will highlight recent advances in characterizing observed structures, geophysical properties, lithologies, and slip behaviors at plate boundary faults at a range of scales, with a focus on relationships between these features. We encourage submissions from seismology, magnetotellurics, geodesy, earthquake rupture modeling, structural geology, fault zone drilling, and experimental work.

Invited Speakers: Thomas Goebel, TBA

S032. The Role of Slow Slip Events in the Earthquake Cycle: Stressing, Triggering, and Hazard

Session ID: 53250

Conveners: Bill Fry (GNS Science), Matt Gerstenberger (GNS Science-Institute of Geological and Nuclear Sciences Ltd), Yoshihiro Kaneko (GNS Science)

Session Description: Several recent great and large earthquakes have been correlated with slow slip events (SSE) on plate boundaries. Events in Japan, Chile, and New Zealand have preceded or triggered SSE. However, the physical interaction between fast and slow earthquakes is currenty poorly understood and many questions exist, including the relation of SSE to future large earthquakes. Understanding this interaction, either from a physical or statistical perspective, is crucial to explaining where and when future large earthquakes may occur.

Ongoing research aims to understand and model the occurrence of SSE. However, scant research specifically focuses on the role of SSE in triggering fast earthquakes. We invite contributions which investigate if and how SSE can trigger large earthquakes using such methods as physics based modeling (e.g., Rate and State Friction, seismicity simulators, stress modeling, etc.), empirical modeling or observations (e.g., ETAS, rate changes, etc.), paleoseismology or any study providing insight into this problem.

OS018. Geologic Evolution of Continental Shelves

Session ID: 48962

Conveners: Shannon Klotsko (San Diego State University), Ashley McCleaf Long (Coastal Carolina University), Jillian Maloney, San Diego State University, Jenna Hill, USGS, Pacific Coastal and Marine Science Center

Session Description: The geologic evolution of continental shelves is linked to large-scale driving mechanisms including tectonics, climate, and sea level variations. On shorter timescales, processes that shape continental shelves include sediment dynamics associated with waves, tides and currents, as well as biologic activity and submarine groundwater discharge. These processes operate across various spatial and temporal scales, adding complexity to interpretations linking processes to morphology. Furthermore, continental shelves cycle between subaerial exposure and submergence associated with sea level fluctuations that repeatedly reshape the shelf and render the shoreline an artificial boundary in landscape evolution. We encourage submissions from onshore and offshore studies that investigate a broad range of topics including fluvial drainage history, sediment dynamics, paleoshorelines, drowned landscapes, shelf morphology and geologic framework controls on benthic habitats from both passive and active continental shelves worldwide. We welcome contributions from field observations including geophysical surveys, outcrop and core studies, landscape modeling, and laboratory experiments.

T017. Exploring Subduction Initiation Processes and Subduction Zone Dynamics: New Insights from Scientific Drilling, Marine Geophysics and Ophiolites

Session ID: 47413

Conveners: Joann Stock, Brandon Shuck, Anders McCarthy, and Marco Maffione

Session Description: Fundamental processes controlling the genesis and recycling of the earth’s crust are linked to the dynamics of subduction initiation, and the evolution of mature subduction zones through time. Constraining such processes requires a combination of multidisciplinary studies, including ocean-drilling expeditions, seafloor geophysical and seismic exploration, field analyses of ophiolites preserved in mountain belts, and modeling. New data from these areas are advancing knowledge of the pre-existing structure of the plates, the initial stages of subduction initiation and arc inception and finally the development of mature subduction zones and mature arc settings. This interdisciplinary session solicits contributions from recent and past scientific drilling projects (IODP/ICDP), imaging structures and geophysical characteristics of oceanic lithosphere and nascent subduction zones, and recent advances in field, laboratory, and modeling studies constraining subduction processes from inception to arc development.

Invited Speakers: Michael Gurnis (Caltech) and Julie Tugend (ISTEP)

T032. Oceanic Lithosphere: Structure and Evolution from Creation to Destruction

Session ID: 47286

Dear Colleagues,

We would like to encourage submission to the AGU 2018 session “Oceanic Lithosphere: Structure and Evolution from Creation to Destruction”, which may be of special interest to the GeoPRISMS community. The aim of this session is to explore what we know about the variability in oceanic crust and lithosphere both in space and over time using a range of geophysical, geochemical and geodynamic methods. Please see below for the full session description and information.

Adrian Doran, Jennifer Harding, and Zhitu Ma

Conveners: Adrian Doran (Scripps Institution of Oceanography), Jennifer Harding (University of Texas at Austin), Zhitu Ma (Brown University)

Session Description: The oceanic lithosphere, the rigid plate covering 70% of the Earth’s surface, controls a broad range of surface and deep-Earth processes, including heat flow and energy transfer at small and large scales. Our understanding of this region has been historically limited due to its vastness and the difficulty of data collection, but recent advances in analysis and instrumentation warrant examining new perspectives on the oceanic lithosphere. We invite new science focusing on the magnitude and wavelength of heterogeneity of oceanic lithosphere in space and time from a diverse range of disciplines, including but not limited to geodynamic modeling, petrology & mineralogy, seismology, and electromagnetic methods . We also encourage submissions pertaining to the accretion of oceanic crust at spreading centers, hotspots, continental margins, fracture zones, volcanoes, thermal properties, and subduction zones.

Invited Speakers: Jim Gaherty (LDEO), Maxim Ballmer (ETH Zurich)

T035. Seafloor Geodesy — Measuring Deformation of the Seabed

Session ID: 48712

Conveners: Martin Heesemann, Ocean Networks Canada, Kelin Wang, Geological Survey of Canada, Yusaka Ohta, Tohoku University, Matthew Cook, Scripps Institution of Oceanography

Session Description: Seafloor geodetic methods allow for measuring crustal deformation over Earth’s vast areas that are covered by water, and therefore inaccessible to standard geodetic techniques. Over the last decade, remarkable technological progress has been made to increase the precision and scales of observations, while improving the reliability and cost effectiveness of the instrumentation. Unquestionably, seafloor geodetic measurements will continue to significantly advance our understanding of the motion and deformation of oceanic tectonic plates, earthquake processes in subduction zones, and the deformation of submarine volcanoes and spreading centers. Moreover, non-tectonic targets such as slope stability, underwater mass movements, extraction of hydrocarbons, and the sequestration of CO2 into the ocean floor can be monitored. We invite abstracts that highlight seafloor geodetic (e.g. GPS/A, differential bathymetry, seafloor pressure, acoustic ranging, seismometry, gravity, tilt, and strain) measurement systems, data processing methods, observational results, and modeling studies.

S008. Environmental seismology: using geophysical tools for Earth surface processes research

Session ID: 55190

Conveners: Danica L Roth (University of Oregon), Aurélien Mordret (Massachusetts Institute of Technology), Bradley Paul Lipovsky (Harvard University), Michael Dietze, Deutsches GeoForschungsZentrum

Session Description: Recent work has highlighted the generation of elastic waves by processes at or near the Earth’s surface, and seismic techniques are being utilized to examine an increasingly diverse range of processes, hazards and materials. Seismic observations with high temporal resolution and broad spatial coverage of multiple sources and inaccessible environments. Areas of recent advancement include: mass movement (landslides, rockfalls, debris flows, lahars); hydrologic (groundwater, open water waves/tides, outburst floods, turbulence, sediment transport), cryospheric (avalanches, icequakes, calving, ice fracture/deformation, glacial hydrology/sliding), atmospheric and oceanic (microseisms, extreme weather, gravity waves) phenomena; use of large-N arrays; 4-d imaging of substrate, material, and structural attributes; and anthropogenic sources.

This session connects scientists applying theoretical, field-based and experimental seismic methods to Earth surface and near-surface dynamics. We invite contributions from geomorphology, cryospheric sciences, seismology, hazards, volcanology, soil sciences, rock mechanics, hydrology, and related fields.

Sincerely,

Danica Roth, Aurélien Mordret, Bradley Lipovsky, and Micha Dietze

V011. Chemistry and Physics of Redox reactions in the Solid Earth

Session ID: 51600

Conveners: Fred A Davis (University of Minnesota Duluth), Maryjo N Brounce (University of California Riverside)

Session Description: Earth boasts an enormous oxidation/reduction (redox) gradient from its oxidized surface to its reduced, metallic core. The variation in redox potential between, and laterally within, these layers has profound consequences for geochemistry, geophysics, and geobiology. Redox reactions between minerals, melts, and fluids affect stable assemblages in the crust, mantle, and core. Varying concentrations of redox-sensitive elements can change the rheological properties of minerals by influencing defect concentrations. And chemical exchange between the surface and the interior has led to the evolution of physically distinct reservoirs on geologic timescales. This session hopes to foster conversations among a broad range of disciplines, including both geochemistry and geophysics. We encourage submissions describing experimental, modeling, and natural sample studies in igneous and metamorphic petrology, geochemistry, mineral physics, and seismology.

V018. Deciphering Magma-Tectonic Interactions in Rifts, Arcs, Ridges and Volcanic Fields

Session ID: 51311

Conveners: Christelle Wauthier (Pennsylvania State University), Pete La Femina (Pennsylvania State University), James Muirhead (Syracuse University) and Halldor Geirsson (University of Iceland)

Session Description: Magma-tectonic interactions occur at scales from individual magmatic systems to plate boundaries. Numerous studies reveal spatial and temporal relationships between magma intrusions, earthquakes, and volcanic eruptions. Field, geodetic, and modeling studies suggest tectonic earthquakes can trigger volcanic eruptions and intrusions through static and dynamic stress transfer. Conversely, magma transport and storage can generate earthquakes via stress changes in surrounding country rock. In rifting events, magmatic fluids can also help release tectonic stresses. Finally, the combined effects of magmatic, gravitational and tectonic stresses can trigger catastrophic volcanic flank collapse. This session will focus on the analysis and modeling of magma-tectonic interactions as broadly defined above. We particularly encourage multidisciplinary studies utilizing tools in geodesy, volcanology, geochemistry, structural geology, and seismology to decipher relationships between magmatic and tectonic processes. We also welcome studies using stress analysis and/or advanced numerical and analog modeling to understand the link between tectonic and magmatic systems.

We are looking forward to seeing you in Washington D.C!

Sincerely,

Christelle Wauthier, Pete La Femina, James Muirhead and Halldor Geirsson

V026. Integrating perspectives on East African Rift magmatism from satellite to subsurface measurements

Session ID:49407

Conveners: Erin DiMaggio (Pennsylvania State University), Sara Mana (Salem State University), Wendy R Nelson (University of Houston), Christelle Wauthier (Pennsylvania State University)

Session Description: The East African Rift (EAR) System hosts hundreds of active and extinct volcanoes that formed prior to and in close association with continental rifting, offering an extraordinary opportunity to investigate volcanic and magmatic processes in an active rift at different stages of development. The rich history of Cenozoic magmatism in East Africa can be investigated at different scales, from magma generation in the deep Earth to the surficial expression of volcanism to satellite based studies. This session aims to highlight new and innovative research projects that bring together insights from geological, geochemical, and geophysical data sets into a unified framework that will further our understanding of EAR volcanism. We welcome contributions related to EAR magma generation, storage and transport, volatile fluxes and emissions, eruptive history, and volcano-tectonic interactions.

V027. Interdisciplinary Characterization of Volcanic Explosion Source Dynamics

Session ID: 48736

Conveners: Kathleen McKee (kfmckee@carnegiescience.edu), Sarah Albert (salber@sandia.gov), Benjamin James Andrews (andrewsb@si.edu), and Maurizio Ripepe (maurizio.ripepe@unifi.it)

We would like to bring your attention to the 2018 AGU Fall Meeting Session entitled, “Interdisciplinary Characterization of Volcanic Explosion Source Dynamics”. We invite contributions that explore this topic from a variety of perspectives. Please see below for more information.

Session Description: Forecasting the onset and hazards of volcanic eruptions requires an integrated understanding of precursory activity, source dynamics, and impact of erupted products. A quantitative understanding of explosion source dynamics and their associated geophysical observations is key to advancing understanding of more complex and hazardous volcanic eruptions. Volcanic eruptions range from discrete, impulsive, low-intensity explosions (strombolian) to large, sustained, plinian eruptions. Specific source dynamics vary by eruption style and location. Strombolian and Vulcanian explosions produce a variety of signals that can provide insight into specific source dynamics.

We encourage contributions investigating volcanic explosion source dynamics from various approaches such as physics-based modeling, analogue experiments, field observations, and theory. Analyses using geophysical instrumentation (seismic, infrasound, high-speed imagery, gas data, radar, deformation, etc.) are welcome. We also invite contributions using chemical explosions as a proxy for volcanoes.

V037. Sulfur – a unique player for redox evolution, volatile degassing, metal transport in magmatic, volcanic, and hydrothermal systems

Session ID: 46305

Conveners: Xiaofei Pu (University of Michigan), Adrian Fiege (American Museum of Natural History), Tobias Fischer (University of New Mexico), Rita Economos (Southern Methodist University)

Session Description: Sulfur is a remarkable element that plays a major role in a range of volcanic, magmatic, and hydrothermal processes. The presence of sulfur affects the partitioning of various elements between mineral, melt, and volatile phases. The polyvalent and multi-speciation nature of sulfur in these phases makes it a unique proxy for redox processes, but adds significant challenges to sulfur-related research.

Sulfur contents and species in volcanic gasses provide critical information on volcanic activity assessment. In this regard, our understanding of the temporal evolution of volcanic gas signatures is largely dependent on experimental and thermodynamic modeling approaches, combined with field observations.

In this session we aim to facilitate dialogues between the computational, experimental and field-based volcanology, petrology, and economic geology communities, to better understand the role and behavior of sulfur and associated elements in magmatic, volcanic, and hydrothermal systems. Contributions based on interdisciplinary observations and novel analytical techniques are encouraged.

Invited speakers (confirmed): Marc-Antoine Longpré (Queens College, City University of New York – Tentative title: Sulfur systematics record the volatile-rich, oxidized, and recycled nature of the Canary Island mantle source), Echo (Shuo) Ding (American Museum of Natural History – Tentative title: sulfate solubilities and sulfur partitioning between andesitic-rhyolitic melt and C-O-H-S fluid)

V044. Volcano Seismology and Acoustics: Recent Advances in Understanding Volcanic Processes

Session ID: 44116

Conveners: Alexandra Iezzi (Geophysical Institute, University of Alaska Fairbanks), Diana Roman (Carnegie Institution for Science Washington), Weston Thelen (USGS, Cascade Volcano Observatory), Benoit Taisne (Earth Observatory of Singapore)

Session Description: Volcanic eruptions may involve a variety of hazardous phenomena including ash plumes, gas emissions, explosions, pyroclastic flows, lava flows, and lahars. Mass wasting may also occur during periods of volcanic quiescence. All of these phenomena produce seismic and infrasound signals that may provide key real-time information on hazardous surface phenomena. We can also gain insights into volcanic hazards by tracking subsurface processes such as magma and hydrothermal fluid migration using volcano seismology.

Recent advances in analysis and interpretation of seismic and acoustic data facilitate a precise characterization and quantification of the physical processes leading to and producing hazardous volcanic phenomena. However, volcano seismology and acoustics remains an emerging area of research.

We welcome submissions that explore new seismic and acoustic observations, interpretations, models, instrumentation, or techniques that further our understanding of volcanic processes and potentially aid future monitoring efforts.

We look forward to seeing you in Washington D.C.,

Alex, Diana, Wes, and Benoit

MR023. Volatile Elements in Planetary Interiors: Storage, Cycling, and Implications

Session ID: 47263

Conveners: Jin Liu (Stanford University), Jessica Warren, (University of Delaware), Elizabeth C. Thompson (Northwestern University), and Marc M. Hirschmann (University of Minnesota)

Session description: Volatile elements including hydrogen, carbon, nitrogen, oxygen, sulfur, and the halogen group elements play an important role in the dynamics, structure, and evolution of the Earth’s interior, and are believed to play a similarly important role in other terrestrial planets. The cycling of volatile elements between a planet’s surface and interior can be coupled to planetary-scale processes, and volatile elements within a planet’s interior can influence a wide range of properties including redox state, conductivity, rheology, viscosity, melting, and element partitioning. This session aims to unite researchers from the fields of geochemistry, petrology, mineral physics, rock mechanics, seismology, and geodynamics whose work addresses the role of volatile elements in planetary interiors, the stability and cycling of volatile element-bearing phases at extreme conditions, and the influence of volatile elements on geological processes within the Earth and other terrestrial bodies.

Invited Presenters: Oliver Tschauner (University of Nevada, Las Vegas) and Ananya Mallik (Brown University)

We look forward to seeing you in Washington, D.C.!

On behalf of the conveners,

DI022. The Role of Lithosphere Heterogeneities in Shaping Plate Kinematics and Subduction Dynamics

Session ID: 50620

Conveners: Roberta Carluccio (University of Melbourne), Lorenzo Colli (University of Houston), Jennifer M. Garrison (CalState – LA), Gideon Rosenbaum (University of Queensland)

Session description: The lithosphere constitutes the upper thermal boundary layer of mantle convection. It is well established that its properties exert a fundamental control on solid Earth dynamics by determining the tectonic regime. Moreover, the lithosphere provides a primary source of thermal and chemical anomalies for mantle convection when it is injected in the mantle as subducting slabs.

Some lithosphere heterogeneities include rheological stratifications, sutures, fracture zones and, lateral and vertical variations in temperature and composition. These exist at various scales and play a major role in determining subduction dynamics and the degree and style of lithosphere-mantle coupling processes.

This session aims to highlight recent advances in constraining the scales and amplitudes of heterogeneities in the lithosphere as well as their dynamic role. We welcome multidisciplinary contributions. Some key areas of interest are lithospheric structure and morphology, subduction kinematics and dynamics, slab-mantle interaction and slab deformation, active margin tectonics and subduction-induced seismicity.

Invited speakers: Sung-Joon Chang (Kangwon National University), Luca Dal Zilio (ETH Zurich)
