This is the largest magnitude Irish earthquake ever recorded!

Mayo County has a population of 132,000 and very little earthquake resistant building measures! The epicenter was located 50km off the west coast of Ireland.

Locals in a number of areas on the west coast reported feeling earth tremors this morning. Tremors were felt in counties Mayo, Sligo and Galway with some local radio stations receiving calls from listeners who described houses shaking.
