David Andrews Mr. Mc Donnell’s class Today I will be presenting my project on earthquakes in Ireland In this you will see why there are few or no earthquakes in Ireland. An earthquake is the shaking or vibration of the earths crust. It is caused by a sudden release of energy along a fault line. E.g San Andreas fault Earthquakes occur where plates are destructive and where plates are colliding. Ireland gets little earthquakes as it so far away from the plate boundaries. Although there are still some fault lines under the crust of Ireland. Ireland is several thousand miles from the nearest plate boundary. In the past 50 years, Ireland has experienced earthquakes in Donegal, West Cork, and Wexford. On the 26th of January 2012 an earthquake hit Donegal of magnitude of 2.2 according to the Richter scale. The readings were found by a local school and their use of geology equipment. In march 2014 a 2.6 magnitude earthquake affected wexford. The quake which’s epicentre was off the coast of wexford was measured in a welsh weather station. Wexford was hit by small tremors and there was very little damage. In December 2013 a magnitude 2.6 earthquake hit the west Cork area. The epicentre which was 25km south of Court Mac Sherry left trees down, roofs of houses shaking and locals left worrying. Shallow earthquakes Intermediate earthquakes Deep earthquakes Most destructive earthquakes. Focus found close to the earths surface so it is so destructive. Eg. The Chilean earthquake magnitude 9.2 These occur at lower depths in the mantle, when plates melt. These types of earthquake are less destructive that shallow earthquakes but still inflict damage. Eg. Earthquake in italy 2014 magnitude 4. Found very deep in earth mantle. Result of a change in chemical or mineral composition. Eg. San Andreas fault.
