Catalan Seismic Network

In 1996 a new concept of seismic network was designed and planned in order to fulfill two main objectives: i) to provide rapid information for Civil Defense services and society in general and ii) to obtain systematically high quality data for the scientific community.

It is planned to create robust, high performance field infrastructures and install up to 20 stations equipped with three component broadband sensors with high dynamic range. The stations are based on VSAT platforms sending continuous almost real time seismic data via satellite to the Hub at the processing center of the Institut Cartogràfic de Catalunya (ICC).

Data are continuously stored and processed with an automatic location system. Information is disseminated via Internet, after validation by seismologists. Event information and waveforms are available in our web page: Recent quakes .

A detailed description is available at the ORFEUS web (Observatories and Research Facilities for EUropean Seismology) (http://www.orfeus-eu.org/Organization/Newsletter/vol3no1/catalonianet.html).


Implementation programme:

  • In the first phase 1998-2000, the first four VSAT based seismic stations (numbered 1, 2, 3 and 4) with Guralp CMG-40T sensors (0.03Hz-50Hz) are operative, together with the reception and processing center.
  • In the scond phase 2001-2003, 4 new estations (numbered 5, 6, 7 and 8) with STS-2 (0.01Hz - 50Hz) and Guralp CMG-3ESP (0.01Hz-50Hz) sensors have been installed.
  • In the third phase 2004-2007, 7 new stations are constructed in collaboration with the Institut Català del Sòl (INCASOL).
  • The seismic network is complemented with other stations coming from funds of DGCYT and INTERREG projects.

The implementation programme of the Seismic Network is represented in the following sketch (October 2003):
