Identification of a nascent tectonic boundary in the San-in area, southwest Japan, using a 3D S-wave velocity structure obtained by ambient noise surface wave tomography
Abstract We derived a three-dimensional S-wave velocity model for the San-in area of southwest Food Items Japan to examine heterogeneous structures such as tectonic faults.Many earthquakes occur in this area, but much of the activity has been relatively recent, so the fault distribution has yet to be fully clarified.Here, we used continuous ambient
