OHIOSEIS EARTHQUAKE FAQ
Frequently Asked Questions About Ohio Earthquakes

What was the biggest earthquake in Ohio?

The Anna (Shelby County) earthquake on March 9, 1937 was the strongest earthquake to strike Ohio. Few seismographs were available at that time; however, based on the felt area of the earthquake and the damage that occurred in Anna and surrounding communities, the U.S. Geological Survey assigned a magnitude of 5.4 to this earthquake.
