Historical great earthquakes along the Nankai Trough. (Upper) Map showing the rupture segmentation of historical earthquakes. From right to left, stars indicate epicenters of the 1944 Tonankai (region C), 1946 Nankai (region B), 1968 Hyuganada (region Z), and 1662 Hyuganada earthquakes (out of region Z). BC Bungo Channel, CA Cape Ashizuri, CM Cape Muroto, SS Shishikui, KC Kii Channel, CS Cape Shiono, SP Shima Peninsula, LH Lake Hamana, OZ Omaezaki, SB Suruga Bay. (Lower) Timeline of historical earthquakes (Earthquake Research Committee 2013) showing the extent of rupture zones (segment boundaries are shown by vertical lines). Red lines indicate source segments known to have ruptured during historical events. Broken lines indicate probable (orange) and possible (yellow) ruptured segments. The solid purple line indicates a tsunami earthquake or teleseism. The dashed purple lines indicate ruptured segments according to previous studies (Earthquake Research Committee 2013). Italic numerals in parentheses indicate the time intervals between successive earthquakes. Historical records are considered incomplete before 1605 (shaded area). Historical events are named on the right side; names with red backgrounds indicate mega-earthquakes (Maemoku 1988; Shishikura et al. 2008; Okamura and Matsuoka 2012)
