Unraveling the physics behind Kamchatka's 73-year earthquake cycle
A research team from University of Tsukuba and collaborating institutions has clarified why M9-class megathrust earthquakes recur off the Kamchatka Peninsula with an unusually short cycle of 73 years. By analyzing the rupture process of the 2025 event, the team demonstrated that this earthquake exhibited complex behavior that cannot be explained by conventional seismic-cycle models.
The regions bordering the Pacific Ocean live with the seismic risk piled to the ground. From Japan to Chile, the slightest tremor recalls the power of tectonic forces at work. Yet, even in these areas accustomed to earthquakes, some events exceed expectations. The Kamchatka earthquake, which occurred in the middle of the night in July 2025, is now one of the most intense ever measured on a global scale. When the Earth releases out-of-standard en…
