Flooding along the banks of river Shannon near Athlone
Ireland has withstood 80 minor earthquakes in the past 30 years. That's a lot of earthquakes but they were very mild. In 1984,an earthquake of 5.4 magnitude hit Ireland and nothing more powerful than that is expected to occur for awhile or forever. The second largest local earthquake in Ireland was a 4.0 in 2012. With major earthquakes, tsunamis tend to follow. Ireland experienced, what was called a tsunami, in 2011. Although, "tsunami" is a bit of an overstatement because it was roughly a 46cm wave. It is more like a tidal wave according to some articles. Ireland does, however, have hazards of more tsunamis occurring but it seems unlikely to be anything major. Where Ireland is located, it quite a calm location on the Eurasian plate away from any boundaries or volcanic activity. Some ways were discovered on possibilities of tsunamis occurring due to landslides or earthquakes. First, the eruption of the Cumbre Vieja in the Canary Islands could set off a tsunami in Ireland's direction. Second, this thing called a submarine landslide, which is when a large volume of material moves or shifts underwater. Finally, the Azores-Gibraltar fault which caused the two most recent tsunamis in Ireland in 1755 and 1761 due to an 8.6 earthquake in Lisbon. Not so recent, I know. As you can see, Ireland seems like an overall wonderful place to visit or even make it a home! There are no recent disasters but Ireland is always on hazard watch because we can't predict mother nature perfectly, though we try. So go check out some of Ireland's beautiful sites, especially the castles!

Keli,
ReplyDeleteThis was very thoroughly written. You're definitely well informed on the subject, and you're an excellent writer! I especially appreciate the visuals and your clear appreciation for your country. Ireland certainly sees a fair share of natural disasters, but it's lucky that they aren't ever too serious. I find it interesting that there are that many earthquakes without it being seriously damaging. Hopefully, it will continue that way at worst. I do plan on visiting Ireland someday, thanks for the suggestion!
Yes, Ireland is not quite at a boundary like Iceland is...but still, as you say, it will have plenty of other non tectonic related hazards...we'll focus on quakes next week.
