Another light earthquake struck in the Mona Passage between Puerto Rico and the Dominican Republic on Friday evening, according to the United States Geological Survey.
The 3.9-magnitude quake came one day after a 4.7-magnitude quake in the same region.
The quake occurred around 127 kilometres north-northeast of Punta Cana in the Dominican Republic and about 220 kilometres northwest of San Juan, Puerto Rico, at a depth of about 43 kilometres.
It occurred at around 10:50 PM local time, according to the USGS.
There were reports of shaking in Puerto Rico, although there were no reports of damage or injuries.
It was the latest moderately-sized quake in a seismically active region in the Caribbean.
