Mid-Atlantic Ocean — A magnitude 4.8 earthquake struck the northern Mid-Atlantic Ridge early Tuesday morning, shaking a remote stretch of ocean floor far from any coastline.

What happened:

The quake hit at 12:43 AM Central Time, about 10 kilometers below the surface. The U.S. Geological Survey placed the epicenter in the northern Mid-Atlantic Ridge, a long underwater mountain range where tectonic plates pull apart in the middle of the Atlantic Ocean. No tsunami warning was issued.

Impacts:

The earthquake struck far from land, and no shaking was reported in any populated area. The Geological Survey has received no felt reports, and no damage has been reported.

What to do:

People in earthquake country should know the basics. Drop to the ground, take cover under a sturdy table, and hold on until the shaking stops. Stay clear of windows and heavy objects that could fall. After any quake, check for gas leaks, broken glass, and damaged wiring before turning anything back on, and be ready for aftershocks.
