Shelby County was shaken twice Monday by two earthquakes.
The estimated 4.1 magnitude quake hit the town of Timpson, east of Nacogdoches in Shelby County at 4:52 p.m.,, according to the U.S. Geological Survey.
A stronger 4.3 magnitude quake hit about 2 miles northwest of Timpson at 6:51 p.m., according to the survey's website.
Matt Hemingway, with the National Weather Service - Shreveport, said there is a weak fault line in Timpson and earthquakes are a fairly common occurrence, but these were slightly stronger than the average 2.0 to 3.0 quakes on the Richter magnitude scale that are common.
Earthquakes around 4.0 rarely cause substantial damage, but can be felt as far as 60 miles away, according to the survey.
