Locals in parts of Louisiana were shaken Thursday by a magnitude 4.9 earthquake that is now being recorded as the strongest in the state’s history.

According to the United States Geological Survey (USGS), the quake struck at 5:30 a.m. CT, roughly 36 miles southeast of Shreveport, Louisiana, at a depth of about 3.1 miles.

With more than 1,100 reports of earthquake activity so far, the USGS says people living as far north as Shreveport and as far south as western Texas and southern Arkansas reported feeling tremors.

In a Facebook video, the Red River Parish Sheriff’s Office described the strength of the event, calling it the “largest recorded earthquake on Louisiana soil.”

Officials say the region has experienced several smaller earthquakes over the past few years. Most of those incidents were minor, but authorities note they serve as reminders that earthquakes can occur unexpectedly.

The Sheriff’s Office and Office of Emergency Preparedness (OEP) Director Shane Hubbard have been in communication following the quake. Officials say they are coordinating with the Louisiana Department of Natural Resources (DNR) in response to the event.
