The Fabra seismic station (FBR), installed in 1906 and owned by Observatori Fabra, is one of the first seismic stations in Catalonia. As the technology has been progressing, the instruments have been updated and nowadays it is still in operation.

Over the years, the Observatori Fabra has accumulated long series of analog seismic records of the FBR seismic station. It is of common interest for both institutions to preserve and disseminate this heritage and for this reason have begun actions to transfer the recordings to digital form. Some of these records have been scanned in the framework of the SEAL project (Ministerio de Ciencia e Innovación, project CGL2017-88864-R).

The following table presents a complete list of analog seismographs of the Fabra seismic station and their main characteristics. You can check the details of the available scanned recordings selecting, in the table, the name of the instrument.
