No tsunami warnings remain in effect in the US.

Crescent City, California's tsunami warning — the highest level of alert — has been downgraded to a tsunami advisory.

Tsunami advisories are still in place in other parts of California, as well as Hawaii, Alaska, Oregon and Washington.

Tsunami advisories mean possible strong waves and currents are in the area with possible floods along beaches or harbors. People are advised to stay clear of coastal areas.

The largest active volcano in the northern hemisphere began erupting on Wednesday following a powerful earthquake off Russia's far eastern coast.

A bright orange glow reaching above the clouds was visible from far away as lava began flowing from the Klyuchevskoy volcano on Russia's Kamchatka peninsula after the 8.8 magnitude quake — the highest-octane the world has seen in 14 years — shook the region.

"A descent of burning hot lava is observed on the western slope," The Russian Academy of Sciences' United Geophysical Service said in a post on Telegram.

"Powerful glow above the volcano, explosions."

The titanic 8.8 magnitude temblor, which was the strongest the world has witnessed in the last 14 years, had reportedly struck off the coastal city of Petropavlovsk-Kamchatsky in Russia’s far east.

One of this century’s most powerful earthquakes struck off the coast of Russia and generated tsunami warnings and advisories for a broad section of the Pacific, including Alaska, Hawaii and the U.S. West Coast and as far south as New Zealand. Now warnings are being downgraded in most areas, though advisories remain in place as more aftershocks are possible.

The quake registered a magnitude of 8.8 and was centered off the coast of the Kamchatka Peninsula in Russia’s Far East, according to the U.S. Geological Survey. It struck early Wednesday local time, which was still Tuesday in the U.S.

“Any reports otherwise are false,” the statement continued, noting that “local law enforcement are currently on site helping residents through 50 cars at a time to ensure everyone’s safety.”
