According to USGS, a magnitude 2.6 earthquake struck outside of Toledo in northwestern Ohio at 8:17 pm. The Friday evening earthquake generated dozens of reports to USGS’s website and the “Did you feel it?” reporting tool they feature on it. Shaking was felt throughout the Toledo area as well as Perrysburg and Bowling Green, Ohio. The earthquake struck just south of Metcalf Field near Lake Township Hall from a depth of only 6.5 km. USGS says this is the first earthquake to strike within a radius of 250 km in the last three weeks.
According to the Ohio Department of Natural Resources, Ohio has deployed a seismic network with 21 seismograph stations throughout the state that continuously monitor and record earthquake activity. The Ohio Seismic Network (OhioSeis) went online in January 1999, ending a five-year gap during which there was only one operating station in Ohio. Ohio has 24/7 monitoring and coverage by seismic stations with automatic detection, location and magnitude determination.
Earthquake activity in Ohio is not common. The last earthquake hit on March 20 about 14 miles southwest of Gallipolis; it was a magnitude 2.3 event. On February 4, an even weaker magnitude 2.0 event struck near Athens. On January 23, an earthquake of the same magnitude, 2.0, struck near Fairport Harbor.
USGS says Ohio has experienced more than 160 felt earthquakes since 1776. Most of these events caused no damage or injuries. However, 15 Ohio earthquakes resulted in property damage and some minor injuries. The largest historic earthquake in the state occurred in 1937. The 1936 event had an estimated magnitude of 5.4 and caused considerable damage in the town of Anna and in several other western Ohio communities.
