      <description descriptionType="Abstract">The CIVISA seismic network currently ensures the surveillance of geological hazards on the Azores islands, in particular, the ones resulting from the seismo-volcanic systems in this North Atlantic region. The current network contains short-period and broad band seismic stations operating in seven of the nine islands of the archipelago. Data for two stations are available at GEOFON using FDSN network code CP.</description>
