A 5.0-magnitude earthquake struck off the southwestern coast of Puerto Rico on Tuesday morning, rattling an island struggling to recover from a barrage of daily tremors.
The large quake hit an area about 13 miles south of Guanica and was followed by a 3.6-magnitude aftershock just minutes later, according to the United States Geological Survey.
There were no immediate reports of damage or injuries.
The U.S. territory has experienced dozens of earthquakes a day since late December, including a powerful 6.4-magnitude quake that killed one person and destroyed hundreds of homes on Jan. 7. It was the largest earthquake to strike Puerto Rico in over a century and it will continue to produce aftershocks for years to come, USGS officials have warned.
The agency said new earthquakes will be felt on a daily basis for at least several months and the probability of quakes of magnitude 5 or greater remains high.
Thousands of Puerto Ricans have left their homes for some kind of shelter since the series of tremors began, with some people moving their belongings to tents or cars.
