This moderate strike-slip shock measured 5.2 on the moment magnitude scale and had a maximum Mercalli intensity of VII (Very strong). It occurred at 04:36:59 local time 09:36:59 UTC on April 18 near Bellmont and Mount Carmel, Illinois, within the Wabash Valley seismic zone. Earthquakes in this part of the country are often felt at great distances. Tectonic setting Geology of Illinois Illinois Basin Situated in a stable continental region of the Midwestern United States, the Wabash Valley seismic zone (WVSZ) is an area of dispersed seismic activity that encompasses the border areas of Illinois, Indiana, and Kentucky. This broad, multistate zone of intraplate seismicity lay just to the north of the New Madrid seismic zone and comprises both strike-slip and dip-slip earthquake mechanisms across numerous named faults, grabens, and anticlines.Interpreting the Earthquake Source of the Wabash Valley Seismic Zone (Illinois, Indiana, and Kentucky) from Seismic-reflection, Gravity, and Magnetic-intensity Data http://srl.geoscienceworld.org/content/73/5/660 J.

A number of products from it and its subdivisions that relay information to the public over the Internet were displayed during the event. An automated system from the National Earthquake Information Center, for example, sent an initial notification containing magnitude, depth, and location within two and a half minutes of the mainshock.Fault-Plane Determination of the 18 April 2008 Mount Carmel, Illinois, Earthquake by Detecting and Relocating Aftershocks http://authors.library.caltech.edu/16899/1/Yang2009p6510B_Seismol_Soc_Am.pdf H.

The earthquake was felt so far away, compared to earthquakes in other regions, because the old, rigid bedrock beneath much of the Midwest allows the seismic waves to propagate further. Damage Close to the epicenter in Mount Carmel, Illinois, a woman was briefly unable to exit her home due to a collapsed porch, and a two-story apartment building was evacuated because of loose and falling bricks. The Edwards County sheriff's department took reports of minor damage in West Salem, Illinois.http://abc7chicago.com/archive/6088574/ https://web.archive.org/web/20160414084204/http://abc7chicago.com/archive/6088574/ dead April 14, 2016 Associated Press April 18, 2008 ABC7 Chicago 5.2 earthquake rocks the Midwest Just across the Wabash River in Indiana, Unit 4 at the Gibson Generating Station automatically shut down due to its vibration sensors,http://www.tristate-media.com/articles/2008/04/21/pdclarion/news/news1.txt Archived copy April 22, 2008 January 27, 2022 https://web.archive.org/web/20220127063621/http://www.tristate-media.com/articles/2008/04/21/pdclarion/news/news1.txt dead and in Princeton, a woman was cut when a crystal figurine was knocked from a shelf in her home.http://www.14news.com/global/story.asp?s=8191438 https://web.archive.org/web/20120219212656/http://www.14news.com/global/story.asp?s=8191438 dead February 19, 2012 WFIE September 26, 2017 Update: Aftershocks rattle Tri-State Friday A man had an eye injury at an unknown location, but medical attention was not sought.
