Distribution of tilt and strain stations used in the present study. The solid circles represent the Arimura (AVOT), Harutayama (HVOT) and Komen (KMT) observation tunnels, where tiltmeters and strainmeters are located. The solid squares represent borehole tiltmeters of the Japan Meteorological Agency at Yokoyama (a) and Amida-gawa (f), and that of the Sakurajima Volcano Research Center of Kyoto University at Komen (KOM). The solid triangles represent the summit craters of Kita-dake and Minami-dake, and the Showa crater
