Petropavlovsk-Kamchatsky, Russia — A magnitude 4.8 earthquake struck in the Pacific Ocean off Russia's Kamchatka Peninsula on Sunday afternoon, shaking the sea floor well east of the port city of Petropavlovsk-Kamchatsky.

What happened:

The U.S. Geological Survey recorded the quake at 4:38 PM Central Time on Sunday, November 15. It was centered about 141 kilometers, or roughly 88 miles, east-southeast of Petropavlovsk-Kamchatsky, at a depth of about 10 kilometers, or 6 miles, below the surface. The Kamchatka Peninsula sits along the Pacific Ring of Fire, one of the most seismically active stretches of coastline on Earth, where the Pacific plate dives beneath the North American plate.

Impacts:

The quake struck offshore, far from shore, and the Geological Survey has issued no tsunami warning for this event. No felt reports or damage reports have come in so far, which fits with a quake of this size centered well out at sea. People in Petropavlovsk-Kamchatsky and the surrounding peninsula would most likely have felt little or nothing from a tremor this far offshore.

What to do:

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

Stay away from windows, heavy furniture, and anything that could fall.

If you are near the coast and feel strong shaking, move to higher ground right away and stay there until officials say it is safe to return.

Check your home for gas leaks, broken water lines, and cracked walls before turning utilities back on.

Expect aftershocks. Smaller tremors can follow a quake like this for hours or days, so stay alert and be ready to drop, cover, and hold on again.
