2025 Kamchatka Earthquake: Introduction

NASA had installed an AI component in its satellite-based tsunami detection system exactly one day before the earthquake struck. On July 30, 2025, at a point along the Kamchatka Peninsula's southeastern coast, the Pacific Plate slipped beneath the Okhotsk microplate in a magnitude 8.8 megathrust rupture, the largest earthquake in Russia since 1952, the largest anywhere in the world since the 2011 Tohoku earthquake, and the sixth largest recorded since 1900. Within minutes, tsunami warnings radiated outward across the Pacific basin like the wave itself, reaching Japan, Hawaii, the Philippines, New Zealand, and the entire west coast of the Americas. Seven volcanoes on the Kamchatka Peninsula erupted in the days that followed, an occurrence the Institute of Volcanology and Seismology said had not been seen in nearly 300 years.
