4.8 earthquake shakes southern Puerto Rico, rattling many

A magnitude 4.8 earthquake has struck southern Puerto Rico at a shallow depth in the same region that has not stopped shaking since late December

The quake hit near the southern town of Guayanilla at a depth of 7 miles (12 kilometers), according to the U.S. Geological Survey. The tremor initially was reported with a preliminary magnitude of 5.1.

No immediate damage was reported, although many Puerto Ricans were jolted from their beds.

“It was felt everywhere,” Víctor Huérfano, director of the island's seismic network, told The Associated Press.
