Illinois is flanked on its western and eastern borders by two active seismic zones: the New Madrid Seismic Zone and the Wabash Valley Seismic Zone. The New Madrid fault zone is very active. In 1811-1812 the area in southern Missouri was hit by an earthquake that registered 7.5 on the Richter scale.

Is there a fault line near Illinois?
Despite not being located near a large fault line such as those in California, Illinois is at risk. A series of small quakes have been felt along the New Madrid Fault recently as last week; that runs from far southern Illinois to the south and west.

Most faults in Illinois are the result of stresses that were applied to the margins of North America during mountain building or rifting episodes. Faults have developed at many times during earth’s history in Illinois and are still developing today.

Is there a fault line in the Midwest?
The New Madrid Seismic Zone (/ˈmædrɪd/), sometimes called the New Madrid Fault Line, is a major seismic zone and a prolific source of intraplate earthquakes (earthquakes within a tectonic plate) in the Southern and Midwestern United States, stretching to the southwest from New Madrid, Missouri.
What would happen if the New Madrid fault line went off?
Nearly 200 schools and over 100 fire stations would be damaged; 37 hospitals and 67 police stations would be inoperable the day after the earthquake in the state of Missouri. Thousands of bridges would collapse and railways would be destroyed, paralyzing travel across southeast Missouri.

“And in Illinois, the vast majority of induced earthquakes are actually associated with the carbon sequestration.” That’s the removal of carbon dioxide from the atmosphere and placed deep — that is to say, injected — into the earth with a goal of slowing or reversing global warming.
