Mid-Indian Ridge — A magnitude 5.2 earthquake struck along the Mid-Indian Ridge late Tuesday morning, in open ocean far from any coastline.

WHAT HAPPENED:

The quake hit at 11:36 a.m. Central Time. The U.S. Geological Survey puts the epicenter on the Mid-Indian Ridge, the undersea mountain range running down the middle of the Indian Ocean, at a depth of about 10 kilometers, or roughly 6 miles below the seafloor. The ridge is a spreading boundary where two of the Earth's plates slowly pull apart, and earthquakes there are a regular part of that process.

IMPACTS:

No felt reports have come in, which is expected for a quake this far out at sea. No tsunami threat was issued, and there are no communities near the epicenter to be affected.

WHAT TO DO:

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

Stay away from windows and anything that could fall.

After the shaking, check your home for gas leaks, broken glass, and other hazards before moving around.

Be ready for aftershocks, which can follow a quake like this in the hours and days ahead.
