6.7-magnitude earthquake hits the Atlantic Ocean

A strong earthquake measuring 6.7 has struck the North Atlantic Ocean, roughly halfway between Puerto Rico and Africa, according to seismologists. No tsunami warnings were issued.

The earthquake, which struck at 12:16 UTC on Saturday, hit the Atlantic Ocean about 1,360 miles (2,189 kilometers) to the northeast of Puerto Rico, or 1,846 miles (2,972 kilometers) west of Mauritania.

Seismologists at the U.S. Geological Survey (USGS) put the earthquake’s magnitude at 6.7, down from an earlier estimate of 6.9. They said it struck at a shallow depth of about 10 kilometers (6.2 miles).

No tsunami alerts were issued.

“Based on earthquake information and historical tsunami records, the earthquake is not expected to generate a tsunami,” the U.S. National Tsunami Warning Center said in a bulletin.

Because it happened so far from land, no damage is expected and it’s unlikely anyone could have felt the earthquake, which is the second-biggest so far this year. Last month, a 7.0-magnitude earthquake struck off the coast of Malaysia, with no reports of casualties.
