Freak tidal conditions on the coast of Ireland led people to believe there was a tsunami.

Dr Gerard McCarthy, oceanographer with Irish Climate Research and Analysis Unit in the Department of Geography at Maynooth University told The Irish Examiner that he believed the most likely cause of the phenomenon was probably a meteotsunami. He said: "If you imagine someone dropping a large volume of water straight down on the sea, that’s the kind of affect we are talking about.
