Puerto Rico has been hit by a 6.4-magnitude earthquake, resulting in at least one death and causing island-wide power cuts.
This most recent quake, which began early this morning, was the strongest in a series of quakes that have damaged Puerto Rico this week.
Authorities say the island’s power plants suffered some damage and power was shut off as a protective measure.
The US National Tsunami Warning Center said there is no tsunami threat.
The initial earthquake struck just south of the Caribbean island at a depth of 6 miles , according to the US Geological Survey. It was followed hours later by a 6.0 aftershock.
Strong shaking was reported, causing damage to buildings and homes.
