Fig. 1

Location map of central and western Japan. Thick solid lines represent plate boundaries after Bird (2003). Red open circles are epicenters of very shallow (≤ 20 km), historical (1586 ≤ year ≤2013), and large (M ≥ 6.5) earthquakes from the Catalog of Damaging Earthquakes in the World (Utsu 1990, 2002, 2004, the later updates are added by the International Institute of Seismology and Earthquake Engineering) with additional depth data for historical earthquakes (Matsu’ura 2017). Thin blue lines are active faults on land (Research Group for Active Faults of Japan 1991). Contour lines of the PHS slab of the CAMP model (Hashimoto et al. 2004) are also shown every 10 km by thin solid lines. The following acronyms are used: ISTL, Itoigawa-Shizuoka tectonic line; KP, Kii Peninsula; IB, Ise Bay; TB, Tsuruga Bay; NE, northeastern; AM, Amurian Plate; PHS, Philippine Sea Plate; PAC, Pacific Plate; NA, North American Plate; JT, Japan Trench; NT; Nankai Trough; RT, Ryukyu Trench
