Two earthquakes recorded off Irish coast

Two offshore earthquakes were recorded near Donegal and Wicklow in the past 10 days. 
A M0.6 earthquake, located 40km off the Wicklow coast, occurred on Friday (11th) and a second M0.6 quake was recorded 15km NE of the Inishowen peninsula, Donegal on Monday (7th).

Earthquakes regularly occur in the Irish Sea, the most recent of which was M1.3, occurring on the 17th of September 2020. 
The largest magnitude event recorded in the Irish Sea in recent times was the M2.5 earthquake, occurring on the 15th of December 2019.
A 5.4 magnitude earthquake of July 1984 was the largest ever recorded earthquake on mainland Britain, the Llyn peninsula in North Wales to be precise. 
 It was felt throughout Ireland's east coast, as well as Wales and England. 
 It released approximately 15.8 trillion Joules of energy compared to just 500 thousand Joules released separately by last week's quakes. So yes, you would have most definitely felt the 1984 quake!
