A rare 3.0-magnitude earthquake struck near Shreveport, Louisiana, over the weekend, according to the U.S. Geological Survey. The 3-mile deep quake hit just south, southwest of Mooringsport around 1:45 p.m. Sunday, Nov. 13, the agency said.

At least 18 people from as far way as Haughton, Louisiana, reported feeling it. The town of Mooringsport is in Caddo Parish and sits about 20 miles northwest of Shreveport, the state’s third-largest city by population. No other seismic activity has been reported in the region in at least a month, geologists say.

Magnitude measures the energy released at the source of an earthquake and is now used in place of the old Richter scale, according to the USGS. Quakes between 2.5 and 5.4 magnitude are often felt but rarely cause much damage, according to Michigan Tech. (SOURCE)
