Site distributions in and around Hakone volcano. The black triangles indicate the six permanent borehole stations; all but NTT were constructed by HSRI. NTT was installed and is operated by the Japan Meteorological Agency (JMA). The white triangles indicate the three broadband seismometers, which were installed as temporary stations. The red and blue arrows show static tilt changes observed on June 29, 2015 (Table 1). Note that the reference length for the red and blue arrows differs from each other. The black circle indicates the approximate area of Owakudani
