5.7R in Puerto Rico

A 5.7R earthquake was reported in Puerto  Rico at the epicenter in the map shown above. The stress software we produced of the region in Puerto Rico we got in [18N, 66W], while the epicenter was [18.01N, 66.7aW].

No major injuries were reported, Puerto Rico Director of Emergency Management Carlos Acevedo said.

He said some homes were damaged in Guanica, and a home collapsed in Guayanilla.

Some victims of the earthquake posted photos of deep cracks in walls.

The relatively shallow 6-mile-deep quake struck at 6:32 a.m. just south of the island, where it was felt most strongly, according to the U.S. Geological Service. Several smaller temblors followed, including a 4.9-magnitude quake that frightened residents all over again just before 11 a.m., according to the USGS.

There was no tsunami threat, and no casualties had been reported, according to officials.

People were forced outside of their homes, afraid to go back inside, even as preparations and celebrations for Three Kings Day should have been underway. And thousands of residents lost power after the quake affected some of the electrical substations in the area.

“My entire family woke up screaming,” Dr. Sindia Alvarado, who lives in the southern coastal town of Peñuelas, east of Guayanilla, told The Associated Press. “I thought the house was going to crack in half.”

The southwest coastal town of Guánica opened a shelter after several families lost their homes. At least five residences collapsed in the town, according to reports in El Nuevo Día, the island’s largest newspaper.

Gov. Wanda Vázquez Garced urged people to stay composed as residents in the south posted pictures of damaged houses and rocks and boulders blocking roads.

"Citizens must remain calm and have their action plans prepared to protect themselves," Garced wrote on Twitter.

She said she was in touch with the mayors of Guayanilla and Guánica, and bridges and structures that have been inspected following quakes and tremors of the past couple of weeks will be reviewed again.

U.S. Senator Marco Rubio of Florida wrote in a tweet that his office was in contact with authorities in Puerto Rico and will help to provide any federal aid that is needed.

One of the island's most iconic landmarks, the Guánica lighthouse built by the Spanish in 1892, suffered damages after the earthquake. Though the lighthouse's tower survived the quake, one of front walls of the structure collapsed.
