A magnitude 5.9 quake shook Puerto Rico on Saturday, causing millions of dollars of damage along the island’s southern coast, where previous recent quakes toppled homes and schools.
The US Geological Survey said the 0854 local time (1254GMT) quake hit eight miles (13 kilometres) southeast of Guanica at a shallow depth of three miles (five kilometres).
It was followed by several aftershocks, including a magnitude 5.2 temblor less than two minutes later.
No injuries or deaths were reported, officials said.
More landslides and damaged homes were reported, along with severe cracks on a bridge in the southwest coastal town of Guanica.
The Electric Power Authority said outages were reported across much of southern Puerto Rico in the wake of Saturday's quake and crews were assessing possible damage at power plants.
Officials were also going back to reassess structures previously inspected, given the strength of the tremor.
Saturday's quake occurred four days after a 6.4 magnitude quake in the same area and amid a spate of more than 1,100 mostly small quakes over the past 15 days.
