QuakeShake
Quake Shake is a vibrant community of citizen seismologists in Ireland.
QuakeShake: Shaking up earthquake awareness in Ireland 🇮🇪 Join our seismic network of citizen seismologists monitoring Irish and global earthquakes 🗺️
Find more information at our website below ⬇️ The programme is co- funded by Dublin Institute for Advanced Studies (DIAS) and Geological Survey Ireland (GSI). Our mission is to to engage Irish society to contribute to the observation and study of earthquakes in Ireland. Studying earthquakes helps us grasp the Earth’s dynamic and ever-changing nature by examining its ever evolving systems. Check out our website www.quakeshake.ie for more information on all things shaking here in Ireland and Globally.

A magnitude 0.9 earthquake occurred in Northern Donegal on Monday the 21st of September 2026 at 16:03:55 UTC time and 17:03:55 Irish time (earthquakes are recorded in UTC time to avoid confusion with different time zones).
You can see the map with the location of the earthquake (red circle) and the hexagons are Raspberry Shake seismometers.
These are just some of our citizen seismometers that really nicely recorded this earthquake 😍
Thanks to all of our Raspberry Shake hosts 👏🏻

The recent devastating floods in Nepal were they caused by an earthquake?
It is likely no, that an earthquake was not the cause as initially reported. as seismologists we can tell this by looking at the seismics waves our seismometers record.
Because they occur at the surface, they generate weak seismic body waves (P and S waves) but produce strong surface waves (Rayleigh and Love waves) that travel more slowly around the Earth's surface. In our seismograms we can see the squiggly lines (waveforms) look different from each other because different waves types are being recorded 〰️
This video from American Tourist Melissa Blackman shows the moment a large portion of the Branán Mór sea stack near the Cliffs of Moher, Co. Clare, collapsed into the Atlantic Ocean at 12:01 pm local time (11:01 UTC).
After seeing her video on social media via , we wondered if our citizen science network of seismometers in County Clare had picked up the impact?🪨
To our delight, the ground shaking was clearly detected by our Stations R98FA located at the Burren and Cliffs of Moher UNESCO Global Geopark office in Ennistymon and Station RC341 located in Tishmore, Co. Galway. The purple squiggly lines are the waveforms of the collapse producing a detectable seismic event of M0.3 (the energy released by an event of this magnitude is approximately equivalent to the detonation of around 0.3kg of TNT 🧨💥)
You can see our website www.quakeshake.ie/news-and-events/ for more details.
Do you feel like there has been alot of huge earthquakes recently? I do too with all the big magnitude 7.0+ earthquakes in Indonesia, Venezuela and Colombia recently 🙌
But is this actually a record number of large earthquakes?
And what makes us remember an earthquake?〰️
With social media we now see these natural disasters happening so quickly in front of us.
Also to note that infrastructure, depth to hypocentre, population density and many more factors also affect what makes an earthquake memorable to us too.

On the 11th of August 2026 there was a very small magnitude 0.5 earthquake near Tallow Co. Waterford (super close to the Cork border). This was recorded by a few of our QuakeShake citizen Rasperry Shake seismometers recorded in people's houses and schools St Colman's Community College in counties Waterford and Cork 〰️

At 21:58:21 (UTC) (15 August 05:58 am local time) a Magnitude 7.7 earthquake occurred off the north coast of Flores, Indonesia. Flores is one of the Lesser Sunda Islands, a chain which includes Bali, that extends eastwards from Java for several hundred kilometres. The earthquake did raise a tsunami. Wave heights of ~0.2-0.5 meters were detected at various locations.
The earthquake was strongly felt with the epicentre at 10 km depth. The shallow depth and large magnitude produced intense ground shaking across Flores and neighbouring islands. The earthquake caused widespread damage and casualties, with buildings including homes, schools, churches and other public facilities collapsing or being seriously damaged.
The earthquake occurred in one of the most tectonically active parts of Indonesia, where the Australian Plate is moving northwards and colliding with the Sunda–Banda plate system. Around Flores, this movement is accommodated by several active fault systems, including the Flores Thrust, which runs beneath the Flores Sea and forms part of the complex boundary between the Australian and Sunda–Banda plates.

At 12:34:28 UTC (08:34:28 local time), a powerful earthquake measuring M7.4 struck in Columbia, 5 km east of San José del Palmar and approximately 400 km west of the capital, Bogotá.
The earthquake occurred at an intermediate depth of 110km, indicating that it nucleated within the subducted slab, in this case the Nazca plate as it subducts beneath the South America plate. While intermediate-depth earthquakes generally produce less intense shaking than shallower events of the same magnitude, the shaking can still be strong and is often felt over a much wider area.
The event was widely felt in the region, including in Ecuador and Venezuela, and has already resulted in at least 130 fatalities. A state of emergency has been declared, and many buildings have collapsed.
