The Geopark office contributing to science


JCWL Geopark office,

Tuar Mhic Éadaigh


From 2024


JCWL Geopark

QuakeShake, DIAS, GSI

Mayo Dark Sky Park

The Geopark now a laboratory uploading data on earthquakes and light pollution

We are delighted to announce that over the past few months we have added two pieces of equipment recording and sending data continuously

First of all, as part of the QuakeShake project funded by Dublin Institute for Advanced Studies (DIAS) and Geological Survey Ireland (GSI), we have been sent a raspberry shake. These little devices are computers linked to the internet with a simple seismometer constantly recording the movements of the ground. As part of a global raspberry shake network of station all over the world, these simple instruments are able to record and locate even the smallest earthquakes that are hard to detect otherwise. You can find the whole network (including the one operated by our colleagues in the Burren and Cliffs of Moher UGG) on their station view website here. Ours is named S601D and you can see its data streaming online at all times below:

And secondly, with the ongoing efforts of the Mayo Dark Sky park to create a dark sky reserve for the whole county of Mayo, they have sent us a TESS light meter to record the amount of light pollution at night in the skys over Tuar Mhic Éadaigh. The sensor is set on top of the roof of the office and is part of an international network of photometer constantly streaming their data. Our sensor is named stars1057 and its data is visible at the following link. To the left, you can see a snapshot of the data measured over the night of Friday 10 May to Saturday 11 May 2024 when we had such clear skies and the fantastic northern lights display.
