Residents across the Twin Lakes Area were awakened from their slumber early Thursday morning when an earthquake shook homes from the Harrison area into Izard County, according to initial reports.
The United States Geological Survey confirmed the 3.3 magnitude wake struck at 1:42 a.m. Initial data reported the quake was centered 11.2 miles south, southeast of Gassville, at a depth of 19.1 kilometers.
The quake was measured by 23 different recording stations and lasted an estimated 24 seconds. Initial reports from the USGS classify the quake as “light.”
The Twin Lakes Area is considered part of the New Madrid seismic zone, which covers parts of Illinois, Indiana, Missouri, Arkansas, Kentucky, Tennessee, Oklahoma and Mississippi.
The New Madrid zone is most famously know for its earthquakes in 1811-1812 which were estimated from 7.5-7.9 on the Richter scale. Those quakes allegedly caused the the Mississippi River to flow backward, according to reports. Over 4,000 earthquakes have been recorded in the New Madrid zone since 1974.
