Magnitude 2.5 quake hits Monroe County

Posted: Updated:

KNOXVILLE, TN(AP) - The U.S. Geological Survey says a magnitude 2.5 earthquake occurred in Monroe County Saturday night.

According to WATE-TV (http://bit.ly/XUf8SA), the quake happened about three miles northeast of Sweetwater around 8 p.m.

The USGS says earthquakes that are felt but too small to cause damage happen about once a year.

In June, Tennessee National Guard members and emergency response officials held an exercise to simulate the response to a large earthquake along the New Madrid (MAD'-rihd) fault.

The New Madrid zone stretches 150 miles, crossing parts of Tennessee and six other states: Arkansas, Illinois, Indiana, Kentucky, Missouri and Mississippi.

In 1811 and 1812, it unleashed a trio of powerful jolts that rattled the central Mississippi River valley.
