Irish National Seismic Network
The Geophysics Section within DIAS operates and maintains the Irish National Seismic Network (INSN), since 2018 with support from the Geological Survey Ireland (GSI). The INSN has operated since 1978 and currently comprises six permanent seismic stations. Station DSB is operated in collaboration with GFZ in Germany and station VAL is operated in collaboration with Met Eireann and GFZ. Data are transmitted from the seismic stations in real-time to the INSN data centre located in 5 Merrion Square, Dublin 2 and to our international partners GFZ, the British Geological Survey (BGS), ORFEUS and IRIS.
For more information on the INSN please go to https://www.insn.ie.
For further information please contact: Dr Martin Möllhoff, Director of Seismic Networks, martin@dias.ie, tel. +353-1-6535147 ext. 218, www.dias.ie/martin

Irish scientists were members of an international research team that recorded the first-ever detailed description of a volcanic eruption in Ecuador. @griffin_caitlin reports irishexaminer.com/news/arid-4023… Retweeted by DIAS Geophysics

Earthquakes were very much concentrated on the intra-caldera shallow trapdoor fault system. Through the inflation-deflation syscle, the 'sinuous ridge' within the caldera grew by 1.5 m relative to the caldera floor Retweeted by DIAS Geophysics
Have a look at our latest Galapagos research out now in @NatureComms! Great work by @AndyFBell leading this multidisciplinary effort and putting everything together! nature.com/articles/s4146… Retweeted by DIAS Geophysics
The #Galapagos volcanoes have done it again: #SierraNegra2018, an eruption featuring amazing deformation, seismicity and everything else. I contributed with #InSAR data but @AndyFBell @volcano_dr @IGecuador et al. have brought it home! nature.com/articles/s4146… Retweeted by DIAS Geophysics

Happy to see our research #SierraNegra2018 eruption published. Glad to work with @AndyFBell @IGecuador @dias_geophysics @Volcan_Ecuador @sarahjjjaye @marco_bagnardi @MikeJ_Stock @hernarado nature.com/articles/s4146… Retweeted by DIAS Geophysics
New paper out today in @NatureComms on the Sierra Negra volcano, Galápagos. It was wonderful to be part of such a great multidisciplinary team including @AndyFBell @volcano_dr @IGecuador @marco_bagnardi @Volcan_Ecuador @hernarado @sarahjjjaye @MikeJ_Stock nature.com/articles/s4146…
Not all volcanoes are created equal!🌋New multidisciplinary paper out today showing that pre-eruptive processes in Galapagos are very different to Iceland/Hawaii!

Pleased that our paper on the 2018 eruption of Sierra Negra in the Galápagos is out today.

Dr Melissa A Pfeffer & Dr Sara Barsotti from IMO carried out gas measurements in Reykjanes. Despite the ongoing seismic swarm for the last 24 hrs, no increase of gases was detected. Another field campaign is being prepared & the area is under strong surveillance. #EUROVOLC Retweeted by DIAS Geophysics
Grand day for a master class from Florian Le Pape on the @dias_geophysics ocean bottom seismometers. We'll be deploying these as part of the @iCRAGcentre survey led by Andy Trafford & Shane Donohoe @ucddublin to develop a fibre-optic approach for offshore site investigation Retweeted by DIAS Geophysics
An example of selected schools for @AtSeismo are inviting students from nearby schools to share earthquake-related knowledge, thanks to high-motivated students and teachers. Good to see knowledge is transferring into the community. @SubediShiba1 seismoschoolnp.org Retweeted by DIAS Geophysics
Earthquake swarm began this morning close to Fagradalsfjall. An M5.7 earthq. occurred at 10:05 many aftershocks followed. Info will be updated when activity has been reviewed further. Activity is within the Reykjanes peninsula. Other locations of large earthquakes are unreliable. Retweeted by DIAS Geophysics
A seismic swarm is shaking the Reykjanes peninsula, the volcano-tectonic episode close to Grindavík is still ongoing. Several earthquakes of ~M5 have taken place for the past hour. The 10:05 earthquake has been calculated Mw5.65. en.vedur.is/earthquakes-an… Retweeted by DIAS Geophysics
