The National Weather Service’s Pacific Tsunami Warning Center (PTWC) has evaluated an earthquake that struck near Puerto Rico a short time ago and has determined there is no threat of a tsunami to Puerto Rico, the U.S. or British Virgin Islands, or anywhere along the U.S. East Coast.
At approximately 9:10pm local time, an earthquake with a preliminary magnitude of 4.4 occurred in the vicinity of Puerto Rico. Based on all available data to the PTWC, they have determined there is no tsunami threat even though people in the region, especially Puerto Rico, may have felt the Earth shaking.
The 4.4 earthquake struck at 18.0 North, 65.8 West, at a depth of 6 miles. The area is seismically active and while tsunamis aren’t a common occurrence here, they can and do form from strong earthquakes in the region.
