A bomb tested in North Korea earlier this month was so strong that it was felt in Wexford.
It's believed the size-mic station in Wexford picked up an unusual event at 1.41am on the morning of January 6th, at the same time as the reported test in eastern Asia.
Stations in Donegal and Galway also picked up the same 'event'.
Authorities in North Korea claimed that it was a Hydrogen bomb but experts in the field believe it is more likely that the detonation was in fact a less powerful atomic bomb.
