Fig. 7.From: Detection of seismic events triggered by P-waves from the 2011 Tohoku-Oki earthquakeP-wave spectral ratios of the Mw 9.0 Tohoku-Oki earthquake compared with (a) the Mw 6.0 reference earthquake and (b) the Mw 6.5 reference earthquake over the main Japanese Islands. The spectral ratio is averaged between 0.5 and 2 Hz. The Centroid Moment Tensor (CMT) solutions of these earthquakes (Nettles et al., 2011) are shown.Back to article page
