Fig. 11From: Waveform inversion of the ultra-long-period seismic event associated with ground tilt motion during an eruption of Mount Kusatsu–Shirane, Japan, on January 23, 2018Spatial distribution and crack orientation dependence of the residuals between the observed and synthetic waveforms obtained by second grid search about the candidate (d). The locations of candidates (d), (d1), and (d2) are indicated by straight lines on the plane map. See Fig. 5 for details concerning the plotting formatBack to article page
