Southern Mid-Atlantic Ridge — A magnitude 4.9 earthquake struck the southern Mid-Atlantic Ridge early Saturday morning, according to the U.S. Geological Survey.

What happened:

The quake hit at 5:35 AM Central Time on Saturday, November 7, centered in the remote Atlantic Ocean along the southern Mid-Atlantic Ridge, about 10 kilometers below the ocean floor. The Mid-Atlantic Ridge is the long underwater mountain chain where the Earth's plates pull apart in the middle of the Atlantic.

Impacts:

No shaking was reported on land, and no damage has been reported. The quake struck far from any coastline, and the USGS issued no tsunami threat.

What to do:

- If you ever feel shaking, drop to the ground, take cover under a sturdy table, and hold on until the shaking stops.

- Stay away from windows and anything that could fall.

- After a quake, check for hazards such as gas leaks or damaged wiring, and be ready for aftershocks.
