The Japanese government believes that the number of casualties would be huge. [An interplate megathrust earthquake] is predicted in the near future along the Nankai Trough off southwestern Japan. Abstract. In addition, we calculated the tsunami propagation that would be caused by the Nankai Trough earthquake, taking into account the largest class of earthquakes excluded by ERC (see also Hirata et al., this meeting). Above 45°C, concentrations of vegetative cells drop two orders of magnitude and endospores become more than 6000 times more abundant than vegetative cells. AbstractDespite recent observations of slow earthquakes along the Nankai subduction zone, none have been reported in the central Nankai Trough between the Kii Channel and Cape Shionomisaki.

Our 3D CMT catalog of offshore earthquakes and published slow earthquake catalogs (e.g., Kano et al., 2018) along the Nankai Trough depicted spatial distributions of slip behaviors on the plate boundary. This is the last in a series of investigative reports from the Chunichi Shimbun about how figures for the probability of a Nankai Trough earthquake were manipulated for a … In southwest Japan, large earthquakes around M 8 have repeatedly occurred in the Nankai Trough (hereafter referred to as Nankai Trough earthquakes) at intervals of ~100–200 years (Ando, 1975). This work was performed as part of the Chikyu Shallow Core Program (SCORE), which was jointly operated with the Japan Drilling Earth Science Consortium (J‐DESC). Figure 1 illustrates the location of the Nankai Trough together with the epicenter of the 2011 earthquake and the resulting tsunami areas. Prehosp Disaster Med. The regular and slow interplate earthquakes were separately distributed, with these distributions reflecting the heterogeneous distribution of effective strengths on the plate boundary. As there have been no reports of such earthquake-induced landslides during historical megathrust earthquakes along the Nankai–Suruga Trough (e.g., Garrett et al., 2016) and other subduction zones, it would appear that it is extremely rare for an M8 earthquake in the trough to cause deformation of coastal landforms by the generation of submarine landslides.
