Although Ireland is not sitting on any major fault lines, it is well known that earthquakes are very common around the country. Not only are they common, they actually happen quite frequently. According to experts, for as much as earthquakes occur, Irelands earthquakes are commonly known to be small and most of the time go un-noticed.
      The Irish National Seismic Network (INSN) monitors earthquake activity around the island. According to them, there are two major parts in Ireland where faulting occurs - Donegal and Wexford. As of last month Donegal recorded an earthquake at 2.2 on the richter scale, that was considered "normal" for seismic activity in the area.

Disasters are not very common in Ireland. Since Ireland is a island, it seems to be pretty safe in regards to catastrophes. However, there is Irish Aid and Emergency Humanitarian Assistance Funding (EHAF), which provides funding support to save lives in times of a crisis.
