A small earthquake struck the east side of Lima on May 11 at 9:51 p.m. EDT (01:51 May 12 UTC). No damage was reported from the 2.8-magnitude event but many residents of Lima, particularly on the east side of town, reported a booming sound followed by a brief period of shaking. Many thought that the refinery exploded. Approximately 40 felt reports were submitted through the Internet. Most were from the east side of Lima, but reports were received from Ada, Beaver Dam, Elida, Harrod, and Ottoville. Modified Mercalli intensity was III. The event was recorded at Ohio Seismic Network stations throughout western and central Ohio.
Lima is in the Western Ohio or Anna Seismic Zone, a region that has historically been the most active in the state. A magnitude 5.4 event on March 9, 1937 struck Anna and surrounding communities and remains the largest and most destructive Ohio earthquake in historic times. The zone has been relatively quiet for the last decade.
