WASHINGTON, Jan. 11 (Xinhua) -- A 5.9-magnitude earthquake rattled Puerto Rico on Saturday morning, the latest in a series of strong temblors that have shaken the island.
The quake occurred at 8:54 a.m. local time (1254 GMT) around 13 kilometers southeast of Guanica, a town on the island's southern Caribbean coastline, according to the U.S. Geological Service (USGS).
The USGS revised its initial report of a 6.0 magnitude quake to 5.9.
There are no immediate reports of injuries but local media said the earthquake was felt across most of Puerto Rico and caused damage to buildings and power outrages to several municipalities.
There is no tsunami watch or warning issued, local authorities said.
Puerto Rico has been hit by a number of powerful earthquakes recently.
A 6.4-magnitude earthquake shocked the island on Tuesday, killing one person and injuring nine others.
Over the past several weeks, hundreds of earthquakes, many of which were weak and could not be felt, have occurred in the area, reported the USGS.
Puerto Rico, with a population of 3.4 million, is an unincorporated territory of the United States, located in the northeast Caribbean Sea, approximately 1,600 kilometers southeast of Miami, Florida.
