Fig. 3From: Sequence of deep-focus earthquakes beneath the Bonin Islands identified by the NIED nationwide dense seismic networks Hi-net and F-netSnapshots of seismic energy propagation derived from MS envelopes at the Hi-net stations. Marks A–H in each subfigure are the seismic phases corresponding to the MS envelope in Fig. 2b. Dashed lines represent isodistance lines from the epicenter of the Bonin Mw 6.5 earthquake with intervals of 200 kmBack to article page
