One of the most powerful earthquakes ever recorded has sent a tsunami crashing into a Russian port and smaller waves barreling across the Pacific to the Americas and south to New Zealand.

An 8.8-magnitude earthquake struck off Russia’s eastern coast on late Wednesday morning, local time. The quake triggered tsunami waves across the Pacific that hit Russia, Japan, Canada and parts of the US coast.

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.
