Fig. 9

Hypocenters of VT earthquakes on August 15, 2015. Small circles represent 1 ≤ M < 2 events and large ones represent M ≥ 2 events. The grayscale represents occurrence time of each event. The solid rectangle in (a) represents the location of the obtained dike. Crosses are seismic stations. Hypocenters of small VT earthquakes (M < 1) are not plotted because they cannot be accurately located. b Hypocenters projected on cross sections of A–A′ and B–B′ in (a). Solid triangles represent the position of Minami-dake
