Figure F1. A. The Nankai Trough off southwestern Japan is the locus of subduction of the Philippine Sea plate (PSP) beneath Honshu and Shikoku islands. Yellow arrow = convergence direction of PSP and Japan. This regional bathymetric map shows the rupture zones of the last two great subduction earthquakes (1944, 1946). Stars = epicenter locations for earthquake nucleation. Red outline = location of NanTroSEIZE drilling area. Inset shows the location of the Nankai Trough.
