Puerto Rican officials are evaluating the damage after a 5.8 magnitude earthquake and a subsequent 5.1 magnitude aftershock struck the U.S. territory early Monday.
According to the U.S. Geological Survey, the initial quake, centered about 8 miles south-southeast of Indios, occurred shortly after 6:30 a.m. local time. The National Weather Service tweeted that the temblor did not pose a tsunami risk.
According to The Associated Press, the earthquake caused "small landslides," damaged homes and knocked out power in some areas.
The second earthquake, which was reported around 10:51 a.m., struck about 4 miles south of Tallaboa, according to USGS officials.

"This is one of the strongest quakes to date since it started shaking on Dec. 28," Angel Vazquez, emergency management director for the city of Ponce, told the AP. "It lasted a long time."
