A phreatic eruption occurred at the summit of Mount Ontake on September 27, 2014, killing more than 50 climbers who were enjoying the excellent autumn weather with colored leaves. The eruption process was recorded with seismic and geodetic observations, and there are many eyewitnesses who survived the eruption. This available data provides us a unique opportunity to understand the volcanic process involved in the phreatic eruption and can help to reduce the risk associated with future phreatic eruptions. This special issue pursues a multidisciplinary approach to assessing the eruption of the Ontake volcano, combining geophysical, geological, geochemical and other methods.
