Russia’s Krasheninnikov Volcano erupted for the first time in recorded history, sending ash 6 km high. No settlements are threatened. The eruption follows a recent major earthquake in Kamchatka.

The eruption occurred after a huge earthquake struck Russia’s Far East early Wednesday, an 8.8-magnitude temblor that caused small tsunami waves in Japan and Alaska and prompted warnings for Hawaii, North and Central America and Pacific islands south toward New Zealand.
