Fig. 6From: Temporal changes in the distinct scattered wave packets associated with earthquake swarm activity beneath the Moriyoshi-zan volcano, northeastern JapanEnvelopes and hypocenter distribution of the two groups that showed short-term changes in the DSW part. a, b are the same as Fig. 4, but without the overwriting of envelopes. c, d are the relocated hypocenter distributions of the events in groups (a) and (b) (red solid circles). Gray circles denote hypocenter distribution of whole earthquakesBack to article page
