– UNESCO‑IOC’s Pacific Tsunami Warning System prompts timely evacuations for millions across the Pacific.
– Evacuation orders in Japan, Hawaii, California and Pacific islands helped avert major loss despite 4 m waves.
– UNESCO’s Tsunami Ready programme enhances community preparedness through drills, education, and warning networks.
In the aftermath of a powerful magnitude 8.8 earthquake off Russia’s Kamchatka Peninsula on 30 July 2025, UNESCO‑IOC’s Pacific Tsunami Warning and Mitigation System (PTWS) activated swiftly, with coordinated bulletins disseminated by the Pacific Tsunami Warning Center (PTWC). The system utilized data from over 600 seismic stations and 500 coastal and deep‑ocean sea‑level gauges to confirm the tsunami threat—helping trigger timely alerts across Japan, Pacific islands, the US West Coast, and Hawaii.
Evacuations were efficiently carried out in Japan and Hawaii, with up to 2 million people relocated to higher ground, while 1.5‑meter waves hit the Galápagos and 8‑foot surges reached California’s Crescent City. Despite significant seismic activity, no fatalities were confirmed—a testament to the enhanced performance of early warning and preparedness systems. Authorities and analysts praised the robustness of UNESCO’s system and infrastructure resilience for enabling a controlled response under extreme conditions.
UNESCO’s Tsunami Ready initiative—implemented in 43 countries—played a vital role by training coastal communities on evacuation protocols, risk awareness, and response coordination. Regular drills and information campaigns ensured that populations understood how to respond when alerts were issued. Moreover, Pacific-wide Wave Exercises and capacity surveys have helped identify gaps and reinforce operational readiness across the region.
