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.

The eruption occurred after a huge earthquake struck Russia’s Far East early Wednesday, an 8.8-magnitude temblor that caused small tsunami waves in Japan and Alaska and prompted warnings for Hawaii, North and Central America and Pacific islands south toward New Zealand.

A volcano in Russia’s Far East erupted hours after a major earthquake triggered tsunami warnings as far away as California and Chile.
