given whats just happened in japan should we in ireland not be thinking of setting up a warning system here considering the thousands of miles of ocean surrounding us and the fact that there are two tectonic plates colliding in each other half way between america and europe (eurasian and caribbean plates).
Not colliding. Separating. The Atlantic Ocean is slowly getting wider creating an underwater ridge on which Iceland sits. I imagine it would be a huge waste of money considering the infrequency of tectonic activity in the Atlantic.
The last major incident was in 1755 I think. An earthquake destroyed Lisbon and a tsunami caused enormous loss of life along the Iberian coast, in addition to SW England and Galway.
There's always the threat from the Canaries; but that's about as likely to happen tomorrow as Betelgeuse is to go supernova within our lifetimes.
There was also a small tsunami reported at Kilmore Quay in 1854
I suspect it may have been caused by a collapse of a gravel bank or similar, given that it was so localised.
It mentions that there was also a tsunami reported there after the Lisbon Earthquake
The detection of the earthquakes themselves is in place Met.ie Valentia detection of Japanese earthquake DIAS
It is hard to figure out what has actually been implemented along the other lines described in that article. Geological Society of Ireland
There would need to be some effort to inform people what to do in the event of getting a tsunami warning to increase its effectiveness.
Does Ireland have the facility to force all mobile operators to broadcast an SMS to all subscribers?
There's a €100,000 that could have been spent on something useful
gone down the drain .
There was talk from Eamon Ryan of this about a year ago, but as far as I know nothing has happened.
It would be great if the warning system was never used and may never even be needed in the 21st century but there are small risks of serious events. It is difficult to measure that risk though as history may not be a good guide to future events. It would seem prudent to use a relatively modest sum to make a big difference if there is a large or even a small wave to hit somewhere along the Irish coast.
There was some talk about the emergency sms ability but i don't think anything solid has been announced yet. That would be useful in many other emergency situations and not just this type.
Well the scenario often put forward for a Tsunami (mega-tsunami) in the North Atlantic is to do with partial collapse of La Palma island in the Canaries if there is a volcanic eruption. A major fault line developed on the island in 1949 during the eruption that year. It's theorised that half the volcano could slip into the Atlantic if there was a major eruption in the future. Result would be a 50 meter wave hitting the Caribbean/East Coast US. Such a scenario would devastate most of the coast of Ireland.
Of course it might never happen.
Of course it would wash away any hope of a Western Rail Corridor extension. And maybe a few Healy-Raes. Let's look on the positives, eh?
From watching the BBC documentary, I think all geologists interviewed are absolutely certain that it will happen. The question is when. The feeling is that it will happen relatively soon (in geological terms). Any waves generated would reach the Irish coast within three hours. The US coast would bear the lion's share of the carnage that would ensue, however.
There are also other places of danger, such as the area that generated the 1755 Lisbon Earthquake, and there's also the possibility of an earthquake in the Caribbean sending a tsunami to Europe.
I think it's fair to say that a large tsunami striking Ireland would potentially destroy much of Cork, Limerick and Galway and cause tens of thousands of deaths. It would make our current worries seem very trivial indeed.
There is also the possibility of more localised events due to submarine landslides on gravel banks etc.
for the most part is ireland not a fairly high sitting landmass
Well I've often heard Ireland's geology described as "bowl-like". Eg plenty of mountains/high points around the coast (rim) and fairly flat interior. If La Palma did spawn a tidal wave that was 50 metres high hitting NY then it could potentially be higher hitting south coast of Ireland (shorter distance). For example in Galway, Loch Corrib is only 6metres above sea level.
