A tsunami advisory has been issued for Puerto Rico and the U.S. Virgin Islands after an earthquake in the Caribbean Sea, according to the U.S. Tsunami Warning System.
The potential tsunami was triggered by a 7.6-magnitude quake on Saturday evening Atlantic time, according to data from the system, which is part of the National Weather Service. Follow our coverage here.
Tsunamis are a series of long waves caused by a large and sudden displacement of water in the ocean, usually from a large earthquake on or below the ocean floor. Tsunamis radiate in all directions from the epicenter and can cause dangerous coastal flooding and powerful currents that can last for hours or days.
Experts warn that just before a tsunami hits shore, seawater can first be drawn out to sea — exposing large swaths of beach and giving people along the water a false sense that a coast is safe.
As more information becomes available, officials may update, add or cancel tsunami alerts.
