What is going on here!?
The rest of the graphs look the same.
What the deuce!?
The whole of Ireland is practically free of earthquakes. This is clearly a real phenomenon and not a product of reporting - one writer, as early as the 17th century, remarks in describing an earthquake (probably Welsh) felt in Dublin in 1534, that an earthquake is such a rare thing in Ireland that when it happens it is considered a wonder.
One can therefore draw the following conclusions about average recurrence - the UK may expect:
* an earthquake of 3.7 ML or larger every 1 year
* an earthquake of 4.7 ML or larger every 10 years
* an earthquake of 5.6 ML or larger every 100 years.
