Fig. 3From: Intensive seismic activity around the Nankai trough revealed by DONET ocean-floor seismic observationsHypocenter distribution off the Kii Peninsula obtained in this study. Circles indicate hypocenter locations. The color and size of the symbols represent source depth and earthquake magnitude, respectively. Gray triangles are DONET ocean-bottom seismic stations, and diamonds are JMA ocean-bottom seismic stations.Back to article page
