The U.S. Geological Survey says a powerful earthquake has occurred in the Gulf of Mexico, sending shock waves to parts of the U.S. Gulf coast.
The agency says no damage or casualties have been reported from the 6.0 magnitude earthquake that struck earlier Sunday.
It says the quake was centered 400 kilometers southwest of St. Petersburg, on the western coast of Florida.
The quake could be felt from Louisiana to Florida. The Geological Survey says there is no danger of a tsunami.
