Map of the study area: a Tectonic setting around Mount Fuji. Thick black lines, plate boundaries of the Philippine Sea Plate, the American Plate, the Okhotsk, and the Pacific Plate; triangle, location of Mount Fuji; star, hypocenter of the Tohoku-Oki earthquake. b Map of Mount Fuji with topography. Blue squares, seismic stations installed by the Japan Meteorological Agency, the National Research Institute for Earth Science, and the Earthquake Research Institute; orange circles, Hi-net stations installed by the National Research Institute for Earth Science13; white star, epicenter of the Shizuoka earthquake; black square, meteorological station installed by the Hot Spring Research Institute of Kanagawa Prefecture. All of the seismic stations are equipped with three-component short-period sensors or broadband seismic sensors, with a sampling interval of 0.01 s.
