Description :
On 19 September 2003, 40 landslides occurred on the slopes of Dooncarton mountain (Republic of Ireland) during a storm. The landslides were investigated to determine the reasons for such a high density of slope failures. It is concluded that most of the landslides were probably caused by a combination of excess water pressures in the buried soil horizon and the thinner overburden of peat or peaty soil associated with the steeper slope segments.
