Fig. 1.

(a) Location of Shinmoedake volcano, in the Kirishima volcano group, and the seismic array used for this work. The inset shows the study site location in southwest Japan. The contour interval is 100 m. Solid and open circles show inflation and deflation pressure sources, respectively, estimated from GPS data (Japan Meteorological Agency, 2012b). The inflation occurred from 1 December, 2009, to 15 January, 2011, before the 2011 eruption, and the deflation was associated with the sub-Plinian eruption of 26 January, 2011. A conceptual model (Fig. 12) is illustrated along the approximate orientation of the cross-section AB. (b) Configuration of the seismic array (open circles). The station marked with a gray circle was not used due to a timing problem. (c) Beam-forming array response at 2.5 Hz for east and north components of the slowness from −0.8 to 0.8 s/km.
