[CEUS-earthquake-hazards] AGU Session of relevance to earthquake hazards in the Central and Eastern US

[Oliver Boyd]

Heather Deshon, Jer-Ming Chiu, Leonardo Ramirez-Guzman and Oliver Boyd would
like to make you aware of and encourage you to submit abstracts for the
following session at the upcoming Fall AGU meeting in San Francisco, Dec
15th to 19th, 2008. Abstracts are due Sept 10th, 2008.

 

S20 Crust and upper mantle structural models beneath the central and eastern
US 

The 1811-1812 New Madrid series of earthquakes occurred in a relatively
unpopulated region of the central United States between Memphis and St.
Louis and were felt over most of the central and eastern United States and
some parts of Canada, a felt area nearly 20 times larger than the area
impacted by the similarly sized 1906 San Francisco earthquake. A better
understanding of the temporal and spatial distribution of shaking and damage
from St. Louis to Memphis that accompanied the great 1811-1812 earthquakes
and other historic events, will reduce uncertainty about potential damage
from similar earthquakes as well as provide the public with a provocative
view of the potential impact of a recurrence of these events. In order to
perform realistic computer simulations of such earthquakes and assess
seismic hazard, updated comprehensive and detailed structural models are
needed for the region. This session seeks contributions that constrain the
lithologic, tectonic, geophysical and geotechnical structure of the Central
United States lithosphere. Contributions that address solutions to
complications arising from attempts to image within and beneath thick
sedimentary basins are particularly encouraged.
