San Juan: An earthquake of 5.7 magnitude has jolted Puerto Rico on Monday. It is the strongest quake yet to hit the United States.
Reports said the territory was shaking for the past week. The U.S. Geological Service said the tremors struck just south of the island at a relatively shallow depth of 10 kilometers (over 6 miles). There was no tsunami threat, officials said.
Power outages were reported in some parts of Puerto Rico following the quake, Angel Vazquez, the emergency management director said. He said: “This is one of the strongest quakes to date since it started shaking on December 28. It lasted for a long time.”
