Special Session at SSA on Mt. Carmel Earthquake

There will be a special session at the April 2009 Seismological Society of America Meeting entitled  “M5.2 Mt. Carmel, Illinois, Earthquake, 18 April 2008”.  The 18 April 2008 M5.2 Mt. Carmel earthquake is the most densely recorded moderate-sized earthquake to date in the Eastern U.S. It is also the largest earthquake to strike the central U.S. in 40 years. The main event and 35 aftershocks were widely recorded by ANSS seismographs across the central U.S. offering an opportunity to study earthquake ground motions having a variety of site conditions including the thick soils of the Mississippi Embayment. Based on USGS Did You Feel It reports the earthquake was widely felt up to 500 km from the epicenter including the cities of Chicago, IL, Indianapolis, IN, Lexington, KY, Atlanta, GA, Memphis, TN, and St. Louis, MO.  This session seeks contributions on source rupture models, geodetic observations, fault plane characterization from aftershocks, site response and basin effects, attenuation, and shaking effects to the built environment and free-field related to this earthquake.  Information about the meeting and abstract submission can be found at the SSA Website: http://www.seismosoc.org/meetings/2009/specialsessions.php
