Pacific tsunami records suggest similar rupture locations of two great Kamchatka earthquakes only 73 years apart
Whether seismic slip can far exceed the slip budget of a subduction megathrust over a short time has important implications to earthquake physics and hazards. The first modern test comes from two great Kamchatka earthquakes of moment magnitude 8.8 to 9.0 in 1952 and 2025. Here, we use tide gauge tsunami records across...
