More on the Coffeeville Quake

From the Mobile Register:

Coffeeville sits on the Bahamas Fault Zone, which runs from northern Florida through the Panhandle, into Alabama's Escambia County and west into Mississippi, said Dorothy Raymond, a geologist with the Geological Survey of Alabama.

Over the past decade, the area has had occasional earthquakes, but they're so deep scientists aren't sure what is causing them, she said. Coffeeville's quake was 3.1 miles below the surface. In 1997, four quakes rattled south Alabama, including one that opened a crack in a Conecuch County road. That year, officials asked for federal funding for seismic monitoring in Alabama.

Never have heard of the Bahamas Fault Zone, but a Google search turns up "Bahamas Fracture Zone" and "Florida-Bahamas Transfer Fault."
