A tsunami warning issued for Hawaii after one of the strongest earthquakes ever recorded, an 8.8 magnitude in Russia's Far East, was downgraded to an advisory after small waves peaked.

A magnitude 8.8 quake hit Russia’s Kamchatka Peninsula, prompting tsunami warnings as far away as the US West Coast.

The 8.8-magnitude quake near Kamchatka in eastern Russia triggered tsunami warnings across Japan and the U.S., including Hawaii, California, Alaska and Oregon.
