<br>
<br><font size=2 face="sans-serif"><b>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. A fairly energetic aftershock sequence
was also recorded by temporary seismograph networks deployed by the University
of Memphis and Indiana University. 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.</b></font>
