MOESM1 of Systematic difference between first-motion and waveform-inversion solutions for shallow offshore earthquakes due to a low-angle dipping slab

Abstract

Additional file 1: Figure S1. First-motion solutions of aftershocks of the 2016 Off Mie earthquake. Focal spheres with magnitudes of 2.5–3.4 were plotted referring the Hi-net catalog (last accessed 19 April 2016). Location of the epicenter of the 2016 Off Mie earthquake is given by the yellow star. Figure S2. Same as Fig. 1b but for four additional earthquakes (Events A, B, D and E of Table S1). Figure S3. 1D velocity structure model by Ukawa et al. [1984]. Red and green lines are depth variations of P- and S-wave velocities, respectively. Figure S4. Theoretical travel using 1D velocity structure model by Ukawa et al. [1984]. Table S1. Parameters of earthquake used in this study. ϕ S , δ and λ are strike, dip, and rake angles of focal mechanism, respectively. Table S2. Physical parameters for each layer. P- and S-wave velocities (V P , V S ), densities (ρ), and anelastic attenuation (Q P , Q S ) of the JIVSM [Koketsu et al. 2012]
