A powerful 8.8-magnitude earthquake has struck near Russia’s Kamchatka Peninsula, triggering a dramatic eruption of the towering Klyuchevskoy volcano. Lava poured down its slopes and explosions lit up the skies just hours after the quake sent tsunami waves racing across the Pacific.

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.
