Gorontalo, Indonesia — A magnitude 5.1 earthquake struck deep beneath the sea off northern Indonesia on Sunday morning.

What happened:

A magnitude 5.1 earthquake hit about 169 kilometers northwest of Gorontalo, Indonesia, at 9:41 AM Central Time. The quake struck at a depth of about 487 kilometers, or roughly 303 miles, below the surface. The U.S. Geological Survey has reviewed the event.

Impacts:

Because the quake was so deep, shaking at the surface was likely light. The Geological Survey had received no felt reports as of this writing, and no tsunami threat was issued.

What to do:

If you 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 the shaking, check for hazards like damaged gas lines or broken glass, and be ready for aftershocks.
