Medieval Irish landscape shaped by tsunamis

In the latest edition of the Journal of the Kerry Archaeological and Historical Society, Alan E Hayden presented a theory that the islands off the coast of Kerry, Ireland were shaped by medieval earthquakes and tsunamis.

Hayden used folklore as well as geological evidence to present his theory, stating that "damage to the south and southwest surrounding walls of Church Island, an important early medieval ecclesiastical site, was ‘unlikely to have been caused by a storm or heavy swell’."
