A massive magnitude 8.8 earthquake struck off Russia's Pacific coast, triggering tsunami warnings and evacuations of coastal areas in Hawaii and alerts along the United States' West Coast.

Waves were reported along a wide swath of the Northern California coast, including in San Francisco. The rest of the state was under a lesser tsunami advisory.

A tsunami warning has been issued for Hawaii, where waves set off by an 8.8-magnitude earthquake in Russia’s remote Far East are expected to arrive after 7 p.m. local time.
