Donegal has been hit by another earthquake, the second in three weeks.
Geologists confirmed the 2.1 magnitude quake occurred at 9.18pm last night in the south of the county.
Geological Survey Ireland tweeted: "A magnitude 2.1 earthquake occurred in Co Donegal on 29 April 2019 at 21:18 local time.
"The earthquake was detected by the Irish National Seismic Network operated by DIAS Geophysics in co-operation with Geological Survey Ireland."
The Irish National Seismic Network (INSN) says local people felt tremors from the quake, the epicentre of which was about 15km south-east from Donegal town and 15km north-east from Ballyshannon.
Last night's quake was recorded at six seismic stations across the country, with tremors felt as far away as Sligo.
The INSN are asking those who felt shockwaves to fill in an online questionnaire here to help gather data on the event.
It comes just three weeks after a 2.4 magnitude earthquake was recorded off the coast of Donegal on April 7.
Locals in Kilcar, Ardara and Ballyshannon all reported feeling the earth move and the quake was recorded at six seismic stations in Donegal, Galway, Kerry, Wexford, Dublin and Louth.
Spokesperson for Geological Survey Ireland (GSI), Dr Siobhan Power told The Irish Daily Mirror: "A magnitude 2.4 earthquake occurred in Donegal Bay late on Sunday April 7, 2019.
"The earthquake was confirmed by the Irish National Seismic Network (INSN) at the Dublin Institute of Advanced Studies (DIAS)."
She went on to explain that earthquake events "are not uncommon in the region" due to a number fault lines in the area.
