A powerful earthquake that struck off the coast of Russia has generated tsunami warnings and advisories for a broad section of the Pacific, including Alaska, Hawaii and the U.S. West Coast

A tsunami advisory was also issued for parts of Alaska and the entire West Coast after a powerful earthquake off Russia's Kamchatka Peninsula.

The 8.8 magnitude temblor struck off the coast of the Kamchatka Peninsula, an isolated strip along the Pacific Ocean, overnight. Residents of the peninsula fled inland as 16-foot waves caused flooding.
