Fig. 7From: Geophysical imaging of subsurface structures in volcanic area by seismic attenuation profilingHypocenter distributions by Sakai et al. (2001). The hypocenters determined by both land stations and OBS during the time range from July 8 to August 2 in 2000 are shown in the left side. The right figures indicate the hypocenters projected to the cross sections of A–B and C–D. A thick chain line shows the lower boundary of the earthquake activityBack to article page
