The Klyuchevskoy eruption was hours after a huge earthquake early Wednesday triggered a tsunami that sent waves across the Pacific.

The Klyuchevskoy volcano on Russia's Kamchatka peninsula began erupting after Wednesday's powerful earthquake in the Pacific, a geological monitoring service said.

Hours after a powerful earthquake struck off Russia's Kamchatka Peninsula, the region's highest volcano began erupting. Geophysicists from the Russian Academy of Sciences reported a strong glow visible at the summit of the 4,750-metre Klyuchevskoy volcano in the Russian Far East.
