A 6.7-magnitude earthquake struck the North Atlantic Ocean at 12:16 UTC on Saturday, roughly halfway between Puerto Rico and Africa, according to the U.S. Geological Survey. The quake occurred about 1,360 miles northeast of Puerto Rico and 1,846 miles west of Mauritania at a shallow depth of approximately 10 kilometers (6.2 miles).

Seismologists initially estimated the magnitude at 6.9 before revising it to 6.7. Despite its strength, the earthquake is not expected to pose a threat to coastal areas due to its remote location.

The U.S. National Tsunami Warning Center confirmed the quake is unlikely to generate a tsunami. Because the epicenter was far from land, no damage is anticipated, and it is unlikely anyone felt the tremor.

This is the second-largest earthquake recorded globally so far this year. Last month, a 7.0-magnitude quake struck off the coast of Malaysia, also without causing casualties. Experts continue to monitor seismic activity in the region, though such mid-ocean quakes rarely result in significant hazards.
