IT HAS happened before - and it could happen again. Ireland's coastline could be struck by a huge tsunami triggered by any one of a number of events.
"Yes we do have the potential for a tsunami because we have been hit in the past," said Prof Mike Williams of NUI Galway.
Don't start counting down the days just yet, he cautions. It will take a large earthquake, underwater landslide or even an asteroid striking the Atlantic before we see the next big one.
Prof Williams will deliver a talk, Irish Tsunami - Myths and Dangers this evening at the Institute of Technology, Sligo, an event planned as part of Science Week.
He became interested in Irish tsunami events when trying to sort out why so many huge boulders lie perched atop cliffs on our coasts and in places like the Aran Islands.
Clearly they had been tossed there by tsunami or storms. After extensive research he decided on an answer. Some were tossed out of the sea in 1839 on the so called "Night of the Big Wind", he said.
More spectacularly, a massive earthquake in the Gulf of Cadiz off Portugal on November 1st, 1755, kicked up a huge wave that pushed into the Atlantic. It rushed up Galway Bay to carry away people and knock down part of the Spanish Arch. The "Lisbon earthquake" had unexpected consequences, Prof Williams said. "It persuaded the king of Portugal to live in a tent for the rest of his life."
A repeat represents the most likely cause of a tsunami today, Prof Williams said, but would be impossible to predict.

TIME AND tide have caused further dramatic erosion at Rossbeigh beach in Co Kerry where the sea has broken through to create an island of the outer tip of the sand spit.
Well known for bathing, horse-riding, surfing and fishing, Rossbeigh beach is something of a sister to Inch Strand, which reaches out from the opposite northern side of Dingle Bay. Inch was made famous internationally in the film Ryan's Daughter.
Shot and directed by
Ciarán O'Connor and voiced by Doireann Ni Briain this is a look into
the work of some of the top scientific minds in the country on climate change.
2 of 'The Investigators' is comprised of 6 x 30 min factual episodes
for RTÉ One. As with Series One, it is a non-studio based factually
informative show aimed at the general viewer. International in
scope it will focus specifically on Ireland's scientific contribution
to the world.
Each week will focus on a specific area of life on which the Investigators are concentrating. The subjects are: Ireland in Space, Ageing, Sensors, Climate Change, Crops of the Future and the Nano Revolution.
This weeks programme 'Climate Change' will focus on the techniques used to represent the physical drivers of climate change as used by the UCD Meteorology and Climate Centre and the Irish Centre for High End Computing, with researchers are looking at Ireland's relationship with the sun and the seas and what the possible results of existing climate change may bring. Viewers will also see the work of glaciologists Paul Dunlop and Sara Benetti who are carrying out investigations into clues left by Ireland's last ice age that may yield clues as to what will happen when the last two remaining ice sheets (Greenland and Antarctica) melt. The programme follow them as they head out to the far shores of Irish waters and drop a drilling core into the sea bed to take samples and analyse the results.
Director and DOP of 'Climate Change' and rest of the series is Ciaran O'Connor while Nuala Cunnigham is series producer. The series was shot from July - November of this year. Filming locations for 'Climate Change' included Dublin, Clonmel, Galway, Coleraine and Reading. Locations for rest of series include: Cork, Carlow, Wicklow, Madrid and Oxford.
