Fig. 6From: Chronology of the 2015 eruption of Hakone volcano, Japan: geological background, mechanism of volcanic unrest and disaster mitigation measures during the crisisa Epicenter distribution during the 2015 unrest and eruption of Hakone volcano (from April 22 to July 31). b Depth distribution of a. Seismicity seems to concentrate along planes likely formed by open cracks; an example in the Kojiri area is shown by depth distributions along strike (c) and dip (d) directions. Temporal seismicity change within the red circles during the unrest is shown in Fig. 7Back to article page
