| Research Abstract |
We newly made detailed map of submarine active faults along the Nankai by interpretation of 3D images processed from multi-beam sonar data recently obtained by Japan Coast Guard. We correlated source areas of large historical earthquakes and location of these active faults, and presented more concrete idea and data for better assessment of location and size of future destructive earthquakes along the trough.
