Tsunami excitation by localized subsidence associated with crater formation: a numerical case study for the October 2023 Sofu Seamount event

Abstract The October 2023 tsunami from Sofu Seamount showed large amplitudes relative to the associated seismic activity, suggesting atypical non-tectonic source processes. Comparisons of pre- and post-event bathymetric data revealed substantial topographic changes at Sofu Seamou...
