Additional file 1: Figure S1. Particle motions on the horizontal plane during the main volcanic tremor (03:25–03:45). (a) The vertical waveform at the N.ASGH stations. Red trajectories in (b) and (c) show the particle motions of velocity waveform on the horizontal plane at each station during the period of harmonic tremor as indicated by the red and yellow rectangles in (a), respectively. Figure S2. Particle motions on the radial–vertical plane during the main volcanic tremor (03:25–03:45). (a) The vertical waveform at N.ASGH stations. Red trajectories in (b) and (c) show particle motions of the velocity waveform on the radial–vertical plane at each station during the period of harmonic tremor during the periods indicated by the red and yellow rectangles in (a), respectively. The radial direction of each trajectory is eastward as shown in the inset of (c). Note that the particle motion in N.ASGH on the radial–vertical plane is not shown owing to the differences in the natural frequency of the horizontal and vertical seismometers. Figure S3. Record section of the tectonic earthquake (35.44010°N, 139.10108°E, depth = 28.46 km, local magnitude = 2.5) that occurred 10 km horizontally NNE from the epicenter of the volcanic tremor. (a) Record section 100 km from N.ASGH station along to N–S section. Zero second on the time axis corresponds to the origin time (09/06/2015 12:52:25 JST). (b) Station distribution. The stations used in this record section are the same as that shown in Figures 2a and 2c. The yellow star shows the epicenter of the tectonic earthquake. Figure S4. Results of the envelope correlation method assuming the P wave velocity structure. The meaning of (a)–(c) is the same as in Figure 4 in the main text. |
