A 4.8-magnitude earthquake shook southern Puerto Rico late on Thursday, leaving aftershocks in a region that has been rattled by clusters of earthquakes and tremors since late last year.
There were no immediate reports of casualties or widespread damage from the earthquake, which was seven miles deep, off the coast of Guayanilla, and just over a mile from Magas Arriba, a suburb of Ponce, the United States Geological Survey said.
“It was felt everywhere,” Victor Huerfano, the director of the island’s seismic network, told The Associated Press.
It was one of strongest to hit the coastal area, where a series of tremors measuring about the same strength or greater had rolled through since late last year, clustered a few miles offshore.
Tremors of 4.7, 5.0 and 4.7 magnitude rocked the island during the night of Dec. 28, and continued for weeks. On Jan. 6, a 5.8-magnitude earthquake shook southwestern Puerto Rico, followed by another strong earthquake days later. On May 2, a 5.4-magnitude earthquake struck about four miles offshore of Tallaboa, the U.S.G.S. said.
The earthquake on Thursday came about a week after Tropical Storm Isaias swept through the Caribbean, causing flooding and landslides.
