Port-Olry, Vanuatu — A magnitude 5.0 earthquake struck in the ocean northwest of Port-Olry, Vanuatu, early Tuesday morning Central time.

What happened:

The quake hit at 5:06 AM Central Time on Tuesday, October 27, centered about 184 kilometers northwest of Port-Olry at a depth of about 10 kilometers, according to the U.S. Geological Survey. A quake at that depth is considered shallow, which can make shaking feel stronger near the epicenter.

Impacts:

No tsunami warning was issued for this quake, and no felt reports had come in at the time of this report. The quake struck offshore in open ocean, well away from towns on Vanuatu's islands.

What to do:

- Drop, cover, and hold on if you feel shaking, and stay away from windows and heavy objects that could fall.

- After shaking stops, check for hazards such as broken glass, damaged power lines, and gas leaks before moving around.

- Stay alert for aftershocks, which can follow a quake of this size, and be ready to drop, cover, and hold on again.
