Three-dimensional velocity structure model for hypocenter determination in and around the Japanese Islands

Abstract We constructed a three-dimensional (3D) velocity structure model to determine hypocenters in and around the Japanese Islands. Whereas one-dimensional (1D) models are good approximations in many cases, the estimated focal depth distribution of hypocenters tends to be affected by the assumed...
