Data of 15 Ocean-bottom seismometers, which were deployed in the area of the Rodriguez Triple Junction, nine (OBS01-OBS07, OBS09-OBS10) at an average distance of ~16 km around the southernmost segment of the Central Indian Ridge (CIR) and another 6 (OBS11-16) in a dense spacing of ~1.9 km at the Kairei hydrothermal vent field. Water depths range from about 2.3 km - 3.9 km. The nine CIR-stations acquired data from 19.12.2019 until the 9.08.2020. The Kairei-stations recorded data from 25.12.2019 until 10.08.2020. All stations recorded with a sampling frequency of 250 Hz using a 6d6 data logger. Time corrections for sensor drift were applied approximating both a linear and non-linear component. While the stations OBS03, OBS06, OBS07 were equipped with 4.5 Hz geophones, all other stations measured the vertical and horizontal components of the seismic wavefield using broad-band seismometers (Trilium Compact 120s). All stations were also equipped with a hydrophone (HTI-04) to measure the pressure wavefield in the water column.

The final catalogue is given in NORDIC format ("RTJ-stC-manualVpVs-Mags-allPicks-WF_selec.nor"). The names of each event datafile is named in the corresponding event's header lines in the catalogue file. Said datafiles (comprising all available channels and stations) can be found in SEISAN database format. Further information on station coordinates, sync times and geophone build can be found in the individual stationinformation files named OBS*.csv, with * being the respective stationnumber.
