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 8.8-magnitude earthquake in Russia's Far East is sending tsunami waves to Hawaii, Alaska, California and Oregon. More countries, like Peru and Chile, are bracing for impact.

Tsunami waves reached Hawaii and the West Coast after one of the strongest earthquakes in recorded history, a magnitude 8.8 temblor, struck off Russia's Kamchatka Peninsula on July 29 before most of the warnings were downgraded hours later.
