Tsunami alerts were issued for Alaska and Hawaii on Tuesday after a major, 8.8 magnitude earthquake struck off the coast of Russia, according to officials.

Hawaii is being warned that "urgent action should be taken to protect lives and property." Watches have been ordered for California, Oregon, Washington and a vast swath of Alaska’s coastline.

Russia’s Far Eastern Kamchatka Peninsula has been rocked by yet another earthquake, this time a magnitude 6.0 tremor, just six days after a catastrophic 8.8 magnitude quake shattered the region and sent tsunami warnings rippling across the Pacific.
