From: Seismicity distribution in the Tonankai and Nankai seismogenic zones and its spatiotemporal relationship with interplate coupling and slow earthquakes

Fig. 11

The location of the active areas for interplate seismicity and very-low-frequency earthquakes (VLFEs). Relocated hypocenters within the 1 km from the plate interface are shown by pink circles. a Numbers from 1 to 14 reflect area code. VLFEs estimated by using the offshore seismic network are shown by green circles (Sugioka et al. 2012; Nakano et al. 2018a; Toh et al. 2020; Yamamoto et al. 2022). Location of the subducted seamount off Muroto and the Paleo-Zenith Ridge is shown by light-blue areas. b VLFEs estimated by using onshore seismic network are shown by yellow circles (Takemura et al. 2019). Other symbols are the same as in Fig. 9
