Alabama Quake History

Hi All Historical records indicate the first earthquake of consequence in Alabama shook residents of Sumter and Marengo Counties, located in the western part of the State, on February 4, 1886. A similar shock occurred nine days later, on February 13. Both were reported felt at communities along the Tombigee River, but caused no damage. Only six months later, the destructive Charleston, South Carolina, shock that was felt in cities all over the Eastern United States occurred. This shock, located about 400 miles east of Alabama's border, caused minor damage in the northeastern part of the State. In 1916 on October 18, a strong earthquake occurred on an unnamed fault east of Birmingham. It was apparently most strong at Easonville. Near the epicenter, chimneys were knocked down, windows broken, and frame buildings "badly shaken." It was noted by residents in seven States and covered 100,000 square miles. It seems that some recent earthquakes in Alabama has gotten the attention of some USGS seismologists as well as Paul Bodin, a seismologist with the University of Memphis Center for Earthquake Research and Information (CERI). One is the magnitude of the first quake M> 4.9, which is high, especially considering Alabama's history of few tremors. The other remarkable factor is the magnitude of the aftershocks: it's very unusual for earthquakes in the Eastern United States to register aftershocks measuring 3.0 or more, Bodin says.
