About the Irish National Seismic Network (INSN)
The Geophysics Section at Dublin Institute for Advanced Studies (DIAS) operates and maintains the INSN with support from Geological Survey Ireland. There are ten seismic stations distributed across the country to form this network. Data are transmitted in quasi real-time from the seismic stations to DIAS' data centre in Dublin, to their international partners and the British Geological Survey (BGS).
Below you can see how the M2.5 earthquake in Donegal was expressed on some of the INSN seismometers:
