The 1968 Illinois earthquake (a New Madrid event) [4] was the largest recorded earthquake in the U.S. Midwestern state of Illinois. Striking at 11:02 a.m. on November 9, it measured 5.3 on the Richter scale. [5] Although no fatalities occurred, the event caused considerable structural damage to buildings, including the toppling of chimneys and ...
The New Madrid Seismic Zone (NMSZ), 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 . The New Madrid fault system was responsible for the ...

New Madrid fault and earthquake-prone region considered at high risk today. The 1811–1812 New Madrid earthquakes were a series of intense intraplate earthquakes beginning with an initial earthquake of moment magnitude 7.2–8.2 on December 16, 1811, followed by a moment magnitude 7.4 aftershock on the same day.
The Sandwich Fault Zone is a fault zone that runs northwest from Oswego to Ogle County, transecting Lee County in Northern Illinois. The fault has generally not been active, although a minor earthquake was reported in 2002 and 2010. [1] On July 15th 2024 at 0253hrs CST a 3.4 magnitude earthquake was recorded with an epicenter roughly 2 km North ...
The USGS has recorded at least 50 aftershocks since the 4.8-magnitude earthquake last Friday. The federal agency announced Thursday that it is installing five new seismometers a few miles from the ...
