A powerful earthquake and a rare volcanic eruption shook Russia's Kamchatka Peninsula and the Kuril Islands, prompting tsunami warnings and raising concerns among emergency officials and seismologists.

Russia's emergency services ministry has warned that smaller tsunami waves could hit three districts of the Kamchatka Peninsula.

A significant earthquake, initially reported at a magnitude of 6.7, struck Russia's Kuril Islands. The magnitude was later updated to 7 by the U.S. Geological Survey and the Pacific Tsunami Warning System.
