Magnitude: 2.7 mbLg
Depth: 5.0 km (fixed)

A small earthquake was recorded by the Ohio Seismic Network on July 26, 2001, at approximately 06:47 a.m. Eastern Daylight time in southern Huron County in north-central Ohio. This 2.7-magnitude event was felt in Greenwich and North Fairfield and points in between these communities. Observers reported a booming sound accompanied by shaking. No damage was reported. This event was recorded by numerous Ohio Seismic Network Stations as well as by Ontario stations of the Geological Survey of Canada.
 
This area of Huron County was the site of a 3.2-magnitude earthquake on November 25, 1998. The November 25th event was widely felt in southern Huron County and in adjacent parts of Richland and Crawford Counties and resulted in numerous calls to emergency officials. No damage was reported for either earthquake.
 
Huron County was not previously considered to be a source of seismic activity; however, a small earthquake in 1927, thought to be in Richland County, and a series of four small earthquakes in northern Ashland County, in the summer of 1940, may have had epicenters at or near the current events. These historic, small-magnitude earthquakes were not precisely located with seismic instruments as are the recent events.
