Ireland and its volcanoes!!!

By studying the type of material and the distribution of sediment, geologists can learn a lot about volcanic activity. 

Eruptions can be predicted in several ways: 

Tiltmeters are highly sensitive devices used to identify any bulges in the volcano's sides. The increased pressure causes the sides of the volcano to bulge, indicating an eruption may be imminent. 

Gas or steam rising from the crater or the appearance of geysers may suggest that an eruption will occur soon. 

Seismometers are used to detect vibrations in rocks. These can be caused by movement of magma or cracking of rocks due to increased temperatures, both of which indicate an impending eruption.

Ireland and Volcanoes
Ireland is not known for its high level volcanic activity in recent history but by studying the landscape volcanoes from hundreds of millions of years ago can be still be seen.
 
There are a number of extinct volcanoes in Ireland these include Slieve Gullion in County Armagh, Croghan Hill in County Offaly, Mount Slemish in County Antrim, Lambay Island in Dublin and Loch Na Fooey in County Galway. These volcanoes are all extinct with the last eruption was approximately 60 million years ago.
 
Today the Geological Survey continues to identify previously undiscovered volcanoes hidden beneath the surface of Ireland. To learn more about these Geophysical surveys visit the Tellus page.

 
Other volcanic activity can also be identified here in Ireland. One of the world’s most famous Geoheritage sites The Giant’s Causeway, is a result of volcanic activity. Approximately 60 million years ago Antrim was at the heart of intense volcanic activity, magma from below the Earth’s surface forced its way up through fissures in the rock and formed a huge lava plateau. As this lava rapidly cooled it contracted forming the famous hexagonal columns.

Ireland and its systems to predict earthquakes

 Today I'm going to talk about Ireland and how they prevent/mitigate earthquakes. 

    The fundamental objective of the Irish National Seismic Network (INSN) activity is to distinguish and find tremors in and close to Ireland. Indeed, we truly do notice seismic tremors in Ireland! The roundabout markers on the guide show the seismic tremors that we identified in and around Ireland starting around 1980. The INSN additionally recognizes enormous seismic tremors that happen anyplace all over the planet. Estimations from our stations add to the worldwide examination into these seismic tremors.

      Ground vibrations are estimated at our seismic stations, see dark triangles on the guide, and sent    through the web to our server farm in Dublin for programmed and manual handling. Quakes are estimated on the Richter scale, a logarithmic scale that goes up in elements of ten, meaning a size 2 tremor is ten times more powerful than a greatness 1.0, etc.  Earthquake researchers use hardware called seismometers to measure the events and despite the fact that Ireland is a moderately steady place, it was Irish researchers Robert Hammer who made the first seismometer in 1846. The three " Hotspot areas" for earthquakes in Ireland are Donegal, Wexford and the Irish Ocean, however the greatest quakes in Ireland are offshore in the Atlantic Ocean in Irish territory. While earthquakes can't be anticipated, researchers can utilize the productive pace of earthquakes in a given region to gauge the probability of getting one more earthquake of a given size, but it doesn't let you know when it will come.

Also just for fun saw this while looking through images of Drop, Cover, and Hold on!
