GEO3BCN Seismic Laboratory is composed by two main sections, the Mobile Seismic Pool and the Seismic Processing Centre. Managing up to 90 broad-band seismic stations, 55 short-period sensors and 250 high resolution nodes, Labsis is one of the major mobile seismic pools in Europe. It is focused in academic uses but it is also directly connected with topics of industrial interest, as hydrocarbon exploration, waste disposal, geological storage or green-house gas emissions.

The Seismic Laboratory is part of the European Research Infrastructure on Solid Earth EPOS-EU. This initiative is a long-term plan to facilitate integrated use of data, data products, and facilities from distributed research infrastructures for solid Earth science in Europe and involves several hundred national infrastructures distributed in 25 countries in Europe.

Seismic Processing Center

The Seismic Processing Center is equipped with eight main servers devoted to calculus, management of storage systems, data distribution, near real- time data acquisition and databases/web integration. Up to 285 Tb of disk space are available. The Seismic Laboratory features connectivity with the Barcelona Supercomputing Center and has research relationships with other computation, processing, interpretation and modelling facilities such as GEOMODELS (University of Barcelona) and the Barcelona Center for Subsurface Imaging.The Seismic Processing Center software includes academic, commercial and in house developments. Explore some of the available packages.

The mobile seismic pool

The Data Acquisition Pool includes seismic equipments intended to be used in temporary deployments. Broad-band and short period seismic acquisition systems are available to allow managing both short-term active seismic profiling and long-term passive seismic deployments.

  1. Broad-Band Pool

    Labsis manages 75 dataloggers equipped with Nanometrics T120 and TC sensors and 15 integrated instruments (Guralp Certimus).

    This pool allow to acquire data deserving further studies on P and S tomographic inversions using natural seismicity, ambient noise, receiver functions, anisotropy studies, surface wave dispersion etc.

  2. Short-period pool

    The Labsis short period pool is composed by 20 WorldSensing Spider dataloggers equipped with robust, easy-to-install 2 Hz seismometers and 35 Nanometrics Pegasus digitizers with Lennartz L3Dlite 1 Hz seismometers.

    This instrumentation is mainly used to acquire active source seismic profiles or to monitor seismicity at local / regional scale (e.g. aftershock analysis).

  3. High Resolution Instrumentation

    The high resolution pool is composed by 250 Sercel nodes with 4.5 Hz and 10 Hz 3D geophones and it is aimed to be used in high density, short duration deployments.

Part of the equipment for this service is part of the EQC2021-006997-P grant, funded by MICIU/AEI/10.13039/501100011033 and the European Union NextGenerationEU/PRTR.
