Puerto Ricans deal with power outages after strong earthquake

Authorities warn aftershocks to continue after 5.8 magnitude earthquake

AIBONITO, Puerto Rico – A 5.8 magnitude earthquake hit on Monday offshore of southwest Puerto Rico leaving thousands without power, damaging some homes and crushing cars.

Earthquakes -- ranging in magnitude from 4.7 to 5.1 -- have been shaking the island’s southern region since Dec. 28.

After the strong earthquake hit about 6:30 a.m., a 4.9 magnitude earthquake followed about 10:50 a.m., according to the U.S. Geological Survey. Scientists expect more aftershocks.

“I’ve spent 29 years with Puerto Rico’s Seismic Network, and it’s the first time I observe this kind of activity,” director Víctor Huérfano told the Associated Press. “There’s no way to predict when it’s going to end, or if it’s going to lead to a major event.”

The island’s fragile electrical grid has been unreliable since hurricanes Maria and Irma hit in 2017.
