Peat mass movements are relatively common in Ireland and potentially highly damaging. They are usually triggered by heavy rainfall but occasionally wind farm construction or other construction activities also cause significant peat slope failures. In August 2008, heavy rainfall in northwestern Ireland triggered several landslides near Geevagh, Co. Sligo, mostly involving peat-covered hillslopes, and a large peat flow occurred a few days later at the site of a new wind farm near Tralee, Co. Kerry. All were inspected very soon after they occurred to obtain visual evidence of site characteristics and conditions as little changed as possible from the time of failure. This paper reports the nature and implications of the landslides and highlights some of the difficulties of assessing potential landslide hazards from Irish blanket bogs.
