This data publication provides supplementary data to the X9_2015 network that was operated from 2015 until 2016 within the KISS experiment in the area of the Klyuchevskoy Volcanic Group. In addition, the associated seismic waveform data are archived in the GFZ GEOFON archive with the https://doi.org/10.14470/K47560642124 (Shapiro et al., 2015) and the associated Scientific Technical Report – Data (Green et al., 2021, https://doi.org/10.48440/GFZ.B103-21019). Please refer to this site for any further information.

Data in the KISS experiment was mainly recorded by Cube3 digitizers which requires a conversion into standard seismological formats including a resampling to adjust the timing of the data to the GPS signals. The data in the GEOFON archive does therefore already include some degree of processing and some loss of information contained in the GPS tags of the raw data. We therefore provide a copy of the raw data as it was retrieved from the Cube digitizers (www.gfz-potsdam.de/gipp → Instruments). Additionally, we provide raw data from the Baikal digitizers and photographs of the sites from the station collection.
