The Ebre seismic station (EBR), installed in 1904 and owned by the Observatori de l'Ebre (OE), is the first seismic station in Catalonia and still active. As the technology has been progressing, the instruments have been updated and nowadays it is still in operation thanks to the collaboration between the OE and the ICGC.
Over the years, the OE has accumulated long series of analog seismograms of the EBR 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. The following table presents a complete list of analog seismographs of the Ebre seismic station (EBR) and their main characteristics. You can  check the details of the available scanned recordings selecting, in the table, the name of the instrument.
