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.
