This data publication provides access to three-component (3C) passive seismic data collected in the National Park La Campana, Chile. The data acquisition was conducted as part of the EarthShape project, specifically the Geophysical Imaging of the Deep Earth (GIDES) initiative. The seismic array was strategically positioned to intersect an existing borehole location. This borehole boasts a wealth of data, including core samples and geophysical logging information. The passive seismic data plays a crucial role in imaging the structure of the deep weathering zone beneath the surface. The dataset includes the raw data captured by the CUBE data logger. This raw data can be converted into the widely used miniSEED format using the freely available GIPP (Geophysical Instruments Pool Potsdam) tools. This conversion facilitates seamless integration with other seismic analysis software, promoting broader utilization of the data by the scientific community.
A network of 400 continuously running, digital, short-period seismic stations was deployed for a time period of approximately 2 weeks in an area of ~1 x 1.7 km in the Geyer region (Saxony, Germany). The network is part of a feasibility study to check whether and to which extent passive seismic methods, i.e. ambient noise techniques with a large number of stations (LARGE-N) can be used in a mineral exploration context. The project is attached to the INFACT project ("Innovative, Non-invasive and Fully Acceptable Exploration Technologies") funded by the European Union's Horizon 2020 programme. At the same time it serves as a first field test for newly acquired LARGE-N instrumentation of the GIPP instrument pool. Waveform data are available from the GEOFON data centre, under network code XF.
A temporary seismic array of short-period seismometers was installed in the 8-story AHEPA hospital, located in the city of Thessaloniki, N. Greece. The scope of the survey was to assess the dynamic characteristics of the RC-building by processing ambient vibration recordings of more than 40 seismic stations installed at different positions in the building. Part of the instruments was used in a soil experiment, outside of the hospital, to study possible Soil Structure Interaction phenomena. In addition to above experiments, a site-specific survey was performed in the Volvi basin, 30km ENE of the city of Thessaloniki. The scope of this experiment was to investigate the soil properties and the geometry of the subsurface geology.
