T sunami alerts were issued for Alaska, Hawaii and the California coast on Tuesday after a major, 8.7 magnitude earthquake struck off the coast of Russia, according to officials. The earthquake occurred about 85 miles off the east coast of Russia's Kamchatka Peninsula with a depth of nearly 12 miles, according to the U.S. Geological Survey.

A powerful 8.8 magnitude earthquake off Russia's far eastern Kamchatka Peninsula has triggered tsunami warnings in Japan and several states in the western United States, including Hawaii, Alaska and California.
