Overview

  • The magnitude 8.8 earthquake off Kamchatka on July 30 triggered an earlier eruption at Kliuchevskoi and prompted tsunami warnings across the Pacific.
  • Krasheninnikov’s ash plume has reached up to 6,000 meters since erupting on August 2–3 without causing casualties or threatening populated areas.
  • Japan evacuated around two million people and the United States and Latin American nations activated tsunami protocols in response to the offshore quake.
  • Russian Ministry of Emergency Situations and international bodies such as the USGS and Pacific Tsunami Warning Center are refining early-warning protocols through enhanced seismic and ash tracking.
  • The sequence of seismic and volcanic activity highlights the volatility of the Kuril–Kamchatka subduction zone and informs future hazard modeling.
