Overview

• A magnitude 8.8 earthquake struck off Russia’s Kamchatka Peninsula on July 30, followed by a magnitude 7.0 aftershock days later.
• Geophysical surveys report that the southern part of Kamchatka has subsided by almost two meters since the initial tremor.
• Six to seven volcanoes—including the long-dormant Krasheninnikov—erupted simultaneously for the first time in nearly 300 years.
• Tsunami warnings issued across the Pacific have been lifted after precautionary evacuations from Russia to Hawaii produced no major casualties.
• Scientists are maintaining heightened surveillance on active vents while analyzing seismic and volcanic data to assess a potential quake-eruption link.
