Overview

• The Krasheninnikov volcano erupted on August 3 for the first time in roughly 400–450 years, sending ash columns up to 6 km high.
• More than 65 aftershocks have rattled Kamchatka since the July 30 magnitude-8.8 quake, including a 6.8-magnitude event, and authorities expect further strong tremors.
• Emergency services and Pacific-wide monitoring agencies have sustained high tsunami and volcanic alerts after earlier 3–4 m waves struck Severo-Kurilsk.
• Russia’s volcanic response team and emergency ministry report that current ash emissions pose no immediate danger to populated areas or air traffic.
• Scientists are analyzing the linked seismic and volcanic activity to improve understanding of tectonic-magmatic interactions and early-warning systems.
