Distribution of slow slip events and the related phenomena in the Nankai subduction zone. The solid and dashed lines represent the Nankai Trough and iso-depth contours of the upper surface of the subducting Philippine Sea plate, respectively (Iwasaki et al. 2015). The pink arrow represents relative plate motion between the Philippine Sea and the Amurian plates (Miyazaki and Heki 2001). The gray shaded area represents the ≥ 2 m slip area of the 1944 Tonankai and the 1946 Nankai earthquakes (Sagiya and Thatcher 1999). Blue and green shaded areas represent the slip areas of L-SSEs (Kobayashi 2017; Takagi et al. 2019) and S-SSEs (Nishimura et al. 2013; Nishimura 2014), respectively. Red dots and orange shaded areas represent epicenters of tectonic tremors (Maeda and Obara 2009; Obara et al. 2010) and
