Geological
Survey Ireland and Dublin
Institute for Advanced Studies
are to invest €1.5m to expand
and upgrade the Irish National Seismic Network. New funding will
result in more stations, greater coverage and more accurate recording
of earthquakes in Ireland.
Dublin Institute for Advanced Studies (DIAS) operates and maintains the Irish National Seismic Network (INSN), see www.insn.ie. In 2018, Geological Survey Ireland (GSI) formalised a new partnership to support and expand the national network.
Since
the first seismometers were installed in 1978, DIAS has collected
seismic data in Ireland. Currently there are six permanent seismic
stations recording ground vibrations in Ireland. These vibrations
vary from very small movements caused by local activities (e.g.
earthquakes and quarry blasts) to large global earthquakes that are
recorded on the Irish network. With GSI support, in 2019 DIAS will
expand this network to 12 seismometers. “The new investment has
allowed us to upgrade our stations and the additional seismometers
will provide data that will enable us to more accurately locate
seismic events and describe their characteristics. These are
extremely sensitive instruments so they can detect movement, even the
very small vibrations, that we don’t usually feel ourselves.”
said Prof. Chris Bean, Head of the Geophysics Section at DIAS.
Data
from these seismometers are transmitted in real-time to DIAS in
Merrion Square, Dublin. Commenting on the new partnership, Mr Koen
Verbruggen (GSI Director) said “In the past we have had to rely on
organisations outside Ireland to deliver information on Irish
earthquakes, this will no longer be the case. Geological Survey
Ireland has a long partnership with DIAS and we are very happy to
support this national monitoring and observational network. The data
will be of great benefit to our country-wide hazard monitoring work,
one of the important aspects of our role as the national geoscience
agency, and understanding the crust beneath Ireland. We are also very
glad to see that the information will be freely available to the
public, researchers and international colleagues through the INSN
website. It is my hope that the presence of this network and access
to the data will foster further collaboration with schools and also
inspire students to look at geophysics and geology as a potential
career path.”
The INSN data are fed into open, international databases (e.g. GFZ (GeoForschungsZentrum, Germany); ORFEUS (Observatories and Research Facilities for European Seismology) and IRIS (Incorporated Research Institutions for Seismology, USA) where it can be accessed in real-time by seismological observatories and researchers for a range of hazards monitoring and research applications. Direct data exchange with the British Geological Survey (BGS) is an important part of the operation of both the INSN and the national seismic network in the UK.
“We
really are part of an international community” said Dr Martin
Möllhoff, Director of Seismic Networks at DIAS. “Seismic data
recorded in Ireland is used to more accurately estimate global events
and is downloaded by researchers around the world. In some cases our
data is particularly useful to international colleagues as we are in
a unique geographical and geological location that produces some very
interesting datasets”.
Geological Survey Ireland has a stand at the BT Young Scientist and Technology Exhibition 2019 January 9th-12th in the RDS, which includes a display from DIAS Geophysics. Come by to see how we record and use seismic data.
