A volcano in eastern Russia erupted for the first time in 475 years, prompting a tsunami warning. The Krasheninnikov volcano in Kamchatka became active days after one of the strongest earthquakes ever recorded hit the region.

Tsunami alerts were issued for Alaska and Hawaii on Tuesday after a major, 8.8 magnitude earthquake struck off the coast of Russia, according to officials.

Russia's Kamchatka Peninsula and surrounding Pacific Rim regions continued to experience seismic instability, with dozens of aftershocks being reported on Saturday by the United States Geological Survey (USGS).
