About INSN

The Geophysics Section within DIAS operates and maintains the Irish National Seismic Network (INSN), since November 2017 with support from the Geological Survey Ireland (GSI). Seismic data and associated local events in Ireland have been recorded since 1978. The station configuration has varied over the years. Currently there are six permanent broadband seismic recording stations in Ireland: Select a station below to view its current seismic data stream.

  • DSB in the Dublin Mountains, operated by DIAS in collaboration with the GeoForschungsZentrum Potsdam (GFZ, Germany)
  • VAL, situated at the Valentia Observatory in Caherciveen, County Kerry, is operated by DIAS in collaboration with Met Eireann
  • IGLA in Oughterard, Co. Galway, operated by DIAS
  • IDGL on Inch Island, Co. Donegal, operated by DIAS
  • IWEX on Carrickbyrne Hill, Co. Wexford, operated by DIAS
  • ILTH on the Cooley Peninsula, Co. Louth, operated by DIAS

Data are transmitted from the six permanent stations in real-time to the DIAS seedlink server located in Merrion Square. Real-time international data exchange is currently taking place with GeoForschungsZentrum (GFZ, Germany), the British Geological Survey (BGS), Instituto Geografico Nacional (IGN, Spain), Instituto de Meteorologil (IP, Portugal) and ORFEUS (Observatories and Research Facilities for European Seismology).

To extract waveform data from any station within the Irish National Seismic Network, please visit the GFZ Archive Portal and cite the INSN data with doi:10.7914/SN/EI.
