Hawaii officials say the timing of the tsunami warning and evacuation orders following this week's massive earthquake off Russia helped make for severe traffic congestion in some areas.

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

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.
