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 magnitude 8.8 earthquake off Russia's far-eastern Kamchatka Peninsula Tuesday triggered tsunami waves across the Pacific Ocean. Russia said the shallow quake caused damage in Petropavlovsk-Kamchatsky and elsewhere on the peninsula and flooded the Kuril Islands with waves as high as 19 feet.
