One of the most powerful earthquakes in modern history shook Russia’s remote east coast Wednesday, sending tsunami waves hurtling across the Pacific Ocean and putting nations from Japan to the United States to Chile on high alert with millions urged to evacuate.

Alerts were issued across the Pacific following the 8.8 magnitude quake in Russia's Far East, but no deaths were reported.

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