Local ground-based geophysical observation data (Borehole tilt, broadband seismic, and infrasound) accompanying the 2018 phreatic eruption at Kusatsu-Shirane volcano (Motoshirane)

<p>A geophysical observation dataset (borehole tilt, broadband seismic, infrasound, and GNSS displacement) accompanying the 2018 phreatic eruption at the Motoshirane cone of the Kusatsu-Shirane volcano. The data was obtained by 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), Yamada et al. (2021), and Yamada et al. (submitted) describe station locations and instrumentations.</p> <p>&nbsp;</p> <p>Tilt (text files: 20190123_stn_1_Hz.txt)</p> <p>format: &nbsp;yy/mm/dd hour:min &nbsp;&nbsp;sec &nbsp;&nbsp;NS tilt &nbsp;&nbsp;EW tilt</p> <p>&nbsp;</p> <p>Broadband seismic and infrasound waveforms (sac files)</p> <p>(ex: 1801230950_stn_cmp.s)</p> <p>*stn: station name</p> <p>*cmp: component</p> <p>&nbsp;</p> <p>GNSS displacement (pos file)</p> <p>(ex: stn1030_0591.pos)</p> <p>*stn: station name</p> <p>Displacements are calculated by kinematic analysis using 960591 (a GNSS station operated by Geospatial Information Authority of Japan) as a base station.
