MOUNT CARMEL — The U.S. Geological Service confirmed a 2.9 earthquake late Friday night, with an epicenter eight miles west of Mount Carmel, just north of Bellmont, near North 14 Blvd. in Wabash County.
USGS reports 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, and a 5.2 quake caused some damage in April 2008.
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, according to USGS.
