Fig. 2

Cumulative coeruptive deformation associated with the 2018 Kusatsu-Shirane phreatic eruption until the end of 2019. a–c Cumulative line-of-sight (LOS) changes until the end of 2019 from the periods of PALSAR-2 image acquisition prior to the 2018 phreatic eruption. Note that positive LOS changes (blue color) indicate an extension of distance between the satellite and the ground, which means displacement occurs away from the satellite. The satellite flight (Flight) and LOS (Beam) direction are shown in each panel by black arrows. Contours indicate 2-cm LOS change intervals. Gray thick arrows indicate the location of Yugama crater lake. Name of volcanoes are shown: the Yugama crater lake (YCL), Ainomine (AI) and Moto-Shirane volcano (MS)
