Houma, Tonga — A magnitude 4.7 earthquake struck in the waters off Tonga early Sunday morning, the U.S. Geological Survey reports.

What happened:

The quake hit at 1:36 AM Central Time, centered about 92 kilometers northwest of Houma, Tonga, in the South Pacific. It struck deep underground, about 178 kilometers below the surface, which is roughly 110 miles down.

Impacts:

No damage has been reported. Because the quake was so deep, shaking at the surface was limited, and the USGS has received no felt reports so far. No tsunami threat was issued for this earthquake.

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 ends, check for hazards like broken glass or damaged gas lines, and be ready for aftershocks.
