The data comprises processed active-source seismic data acquired with land seismometers. The data were collected in the Atacama Desert in connection with expedition SO297 with the research vessel RV SONNE (doi:10.48433/cr_so297) offshore Copiapó, north-central Chile (map for further details). The entire data set consists of 10 land seismometer stations. Seismic data were shot offshore in one profile. Each land station consists of 3 channels (channel 1: horizontal component 1; channel 2: horizontal component 2; channel 3: vertical component).
