Time sequence of the 2015 Hakone eruption. The first signal observed was a rapid tilt change (RTC) at 7:32 on June 29. Erosion of the stream bed, probably due to lahar and/or debris flow, tremor, ash fall and infrasound followed. Note that activity at craters relayed as new craters formed and at the last timing of relay, intensive phases of tremor and infrasound were observed
