Earthquake Summary

The following is a release by the United States Geological Survey, National Earthquake Information Center: A strong earthquake occurred about 250 miles (405 km) south-southwest of Apalachicola, Florida at 8:56 AM MDT, Sep 10, 2006 (10:56 AM EDT in Florida). The magnitude and location may be revised when additional data and further analysis results are available. This earthquake was felt in parts of Florida, Georgia and Alabama. No reports of damage or casualties have been received at this time.

Felt Reports

Items were knocked from shelves and seiches were observed in swimming pools in parts of Florida. Felt (IV) at Brooksville, Crystal River, Kissimmee, Lakeland, Osteen, Palm Coast, Panama City, Port Saint Joe, Santa Rosa Beach, Titusville and Wimauma, Florida. Felt in much of Florida including (III) at Fort Lauderdale, Jacksonville, Orlando, St. Petersburg, Tallahassee and Tampa. Felt in parts of Georgia including (III) at Atlanta. Also felt in parts of Alabama, Kentucky, Louisiana, Mississippi, North Carolina, South Carolina, Tennessee and Texas. Also felt at Freeport, The Bahamas and at Cancun and Merida, Mexico.

Tectonic Summary

This earthquake was centered beneath the Gulf of Mexico, well distant from the nearest active plate boundary. Such "midplate" earthquakes are much less common than earthquakes occurring on faults near plate boundaries, and most probably represent the release of long-term tectonic stresses that ultimately originate from forces applied at the plate boundary. This is the largest of more than a dozen shocks that have been instrumentally recorded from the eastern Gulf of Mexico in the past three decades, and it is the most widely felt. The most recent significant earthquake in the region occurred on February 10th, 2006 and had a magnitude of 5.2. We have not associated this earthquake with a specific causative fault.
