The quake, which had a magnitude of 3.8, happened in the Irish Sea about 13km from the Welsh town of Abersoch in Gwynedd shortly after 4am on Wednesday.
Almost 100 people across Wales, England, and the Isle of Man say they felt tremors.
Meanwhile in Ireland, residents in Carlow, Kildare, Wicklow, Wexford and Dublin reported experiencing the earthquake.
A quake of that size could cause shakes to be felt up to 100km from the epicentre, the British Geological Survey (BGS) claim.
The geosciences centre reports people were woken from their sleep by "the moderate shaking strength of the earthquake, which had a trembling effect".
The BGS states: "Many of the reports stated that windows and crockery rattled. Reports described 'the bed was shaking too scared to look at anything else', 'loud rumbling sound woke me, then noticed the sound of mirror rattling on bedside cabinet', 'gradually grew louder. Classic underground train passing sensation' and 'woke the household any many neighbours'."
Last year a minor earthquake was felt in Buncrana, Co Donegal. The 2.2 magnitude quake woke some residents from their sleep in January 2012, while others said they noticed animals were frightened.
Ireland as a whole is generally classed as having low seismicity, which means it is unlikely to experience earthquakes.
The largest quake to hit the country was magnitude 3.7 and happened in 1951, 16 kilometres off the shore of Co Wicklow on the east coast.
