(1)T25. Megathrusts: 50 years after the 1964 Great Alaska Earthquake – a session in honor of George Plafker
Dear colleagues,
If you are working on the history, processes or source structure of great subduction earthquakes, we invite you to consider submitting an abstract to the Megathrusts session, in honor of George Plafker, at the Geological Society of America Annual Meeting October 18-22, 2014. The meeting will be in beautiful Vancouver, BC and promises to be exciting, with over 250 proposed sessions and two dozen proposed field trips.

Session Description
During the 50th anniversary year of the M 9.2 Great Alaska Earthquake, we will examine advances in coastal geology, paleoseismology, geodetic monitoring, seismology, and geophysical surveys that illuminate, history, processes and source structure of great subduction earthquakes.
Rationale
The M 9.2 Great Alaska Earthquake of 1964 is the second largest earthquake ever recorded. The earthquake and resulting tsunami caused damage throughout the Pacific Basin. The timely work of George Plafker and his colleagues, in documenting permanent ground deformation, surface faulting, and widespread shaking effects, demonstrated that the source was a shallow, landward dipping thrust, and changed the way we view convergent margin tectonics. Recent great earthquakes in Japan, Sumatra, and Chile are a reminder that the subduction zone megathrusts of the Aleutian-Alaskan arc, Cascadia, and Mexico/Central America are America’s largest earthquake sources, with potential for long-range damage. Advances in coastal geology, paleoseismology, geodetic monitoring, seismology, and marine geology and geophysics have improved our understanding of the subduction zone earthquake cycle and its geologic record, but many questions remain. We seek contributions that will highlight the recent advances in earthquake science and hazard assessment of our North American and other subduction zones.
