A look at the Seismograph from Missouri, And A History of Earthquakes in our Region

The United State Geographical Survery (USGS) measures the earthquake as a magnitude 5.2 earthquake.  It was centered 8 miles northwest of Mt. Carmel, Illinois.

The earthquake was felt all across the Midwest.  A couple of our Raycom Media sister stations were on the air live while the earthquake occured.  You can watch the video from their newscasts.  There are links on the right side of the page.

Here is an image of the seismograph from Portageville, Missouri.

 

ADDITIONAL INFORMATION:

EARTHQUAKES IN THE ILLINOIS BASIN - OZARK DOME REGION
Illinois Basin - Oazark Dome Region This large region borders the much more seismically active New Madrid seismic zone on the seismic zone's north and west. The Illinois basin - Ozark dome region covers parts of Indiana, Kentucky, Illinois, Missouri, and Arkansas and stretches from Indianapolis and St. Louis to Memphis. Moderately frequent earthquakes occur at irregular intervals throughout the region. The largest historical earthquake in the region (magnitude 5.4) damaged southern Illinois in 1968. Moderately damaging earthquakes strike somewhere in the region each decade or two, and smaller earthquakes are felt about once or twice a year. In addition, geologists have found evidence of eight or more prehistoric earthquakes over the last 25,000 years that were much larger than any observed historically in the region.

Earthquakes in the central and eastern U.S., although less frequent than in the western U.S., are typically felt over a much broader region. East of the Rockies, an earthquake can be felt over an area as much as ten times larger than a similar magnitude earthquake on the west coast. A magnitude 4.0 eastern U.S. earthquake typically can be felt at many places as far as 100 km (60 mi) from where it occurred, and it infrequently causes damage near its source. A magnitude 5.5 eastern U.S. earthquake usually can be felt as far as 500 km (300 mi) from where it occurred, and sometimes causes damage as far away as 40 km (25 mi).  *Source: USGS
