Mitchelstown Cave is part of the Irish National Seismic Network (INSN). The INSN has 11 seismic stations in Ireland and these are able to detect large earthquakes that happen anywhere around the world. Measurements from these stations contribute to the global research into these earthquakes..
The Dublin Institute for Advanced Studies (DIAS) has the responsibly for monitoring the INSN network and they installed a permanent seismograph 200 feet underground in the Mitchelstown Cave and this is the first underground station in Ireland.
The Seismograph in the Mitchelstown Cave has recorded earthquakes as far away as Southern Peru and the Fiji Islands.
DIAS testing seismograph before installation.
