Distributed acoustic sensing (DAS) data of shallow tremors off Cape Muroto, southwest Japan

Distributed Acoustic Sensing (DAS) strain rate data (hdf5 data) with the Muroto Cable, southwest Japan, when shallow tremors occurred (period: January 30–February 8, 2022).

The DAS measurement is conducted by AP Sensing (model N5200A) with a sensing length of 55 km along the Muroto Cable. Gauge length is 40.4 m. The waveforms were stacked in successive 10 channels to downsample to 51-m channel spacing and decimated to 100 Hz sampling.

The tremor analysis with this DAS data is presented in AGU Fall Meeting 2022 (https://agu.confex.com/agu/fm22/meetingapp.cgi/Paper/1101461) and written in a submitted paper.

The filename show the start time (year-month-day_hour.minute.second) in UT. The data length of each file is one minute. The unit of the data is nstrain/s.
