Description
A geophysical observation dataset (borehole tilt, broadband seismic, and infrasound) accompanying the 2018 phreatic eruption at the Motoshirane cone of the Kusatsu-Shirane volcano. The data is from the local geophysical observation network operated by Kusatsu-Shirane Volcano Observatory, Tokyo Institute of Technology. All time is JST (UTC+9). Terada et al. (2021) and Yamada et al. (2021) describe station locations and instrumentations.
