Alerts for a potential tsunami were issued for coastlines in North America, Hawaii, Russia and Japan after a powerful 8.8-magnitude earthquake struck in the North Pacific Ocean off Russia’s northern Pacific coast, according to the U.S. Tsunami Warning System, which is part of the National Weather Service.

Waves and strong currents are expected to continue Wednesday for Washington but it appears we've escaped largely unscathed.

Officials from Japan to California issued warnings after an 8.8-magnitude quake off Russia’s coast. Hours later, there were no immediate reports of major damage, although some areas remained on alert.

A powerful earthquake off Russia’s east coast triggered tsunami waves across the Pacific, prompting alerts in Hawaii and California.

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.
