A massive 8.8‑magnitude earthquake shook the Kamchatka Peninsula in Russia on July 30, 2025, causing tsunami waves and triggering emergency alerts across several countries. The quake struck southeast of Petropavlovsk‑Kamchatsky at a shallow depth, making it one of the most powerful quakes recorded in over a century.
In Russia, waves up to 5 meters hit Severo‑Kurilsk, leading to flooding and damage to coastal infrastructure. Fortunately, early warnings helped prevent major casualties.
Widespread Alerts Across the Pacific

Japan ordered the evacuation of nearly 2 million residents in 21 prefectures, especially in Hokkaido and Urakawa, after tsunami warnings were issued. Observed waves ranged between 30 cm and 1.3 m, with authorities initially bracing for even higher surges.
