Time series of deformation and earthquakes. a Time series of vertical deformation along the Kiso-Onsen route from April 2006 to October 2014. Relative deformation was measured with respect to the reference point (benchmark BM205). Benchmark numbers are shown in Fig. 1. Orange-colored bars denote the occurrence months of the eruptions in 2007 and 2014. b Time series of vertical deformation along the Yashikino route from April 2002 to October 2014. Relative deformation was measured with respect to the reference point (benchmark BM25). c The monthly number and cumulated number of earthquakes in the summit area of Mount Ontake volcano (rectangle a in Fig. 1) from 2002 to September 2014. d The monthly number and cumulated number of earthquakes involved in swarm activity on the eastern flank of Ontake volcano (rectangle b in Fig. 1). e Time series of the baseline change between the Mitake GEONET benchmark relative to the Hagiwara GEONET benchmark
