Fig. 7From: 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 RMS residuals between the observed and synthetic waveforms obtained by waveform inversion using the three-component broadband seismograms and the two-component tiltmeter records at the three stations (15 components). The locations of candidates (g) and (h) are indicated by straight lines on the plane map. See Fig. 5 for details concerning the plotting formatBack to article page
