Temporal changes in seismicity and other observations associated with the 2013 swarm activity. a Cumulative number of earthquakes between 1 January 2012 and 31 December 2013. The maximum peak ground velocities were measured each day at the OWD station. b Stacked baseline length of GNSS stations around Hakone volcano (Fig. 1a) obtained using the stacking method (Miyaoka and Yokota 2012). c Tilt changes measured by tiltmeters at the KZY (north–south component) and KOM (east–west component) stations. The daily precipitation rates were also plotted
