Abstract

Two shallow translational slides occurred in blanket peat on Skerry Hill, in November 1991 at sites adjacent to slides activated c. 25 years ago. Heavy rainfall, degraded drainage ditches and slope morphology are considered to have been important factors contributing to peat instability. Tension cracks, resulting from either short-term dessiccation or long-term slow mass movement, are thought to have facilated the rapid transfer of heavy rain to the subsurface peat, causing high pore-water pressuresand lubrication of the failure planes. Vegetation recolonization will probably follow a pattern similar to that observed on the adjacent earlier slides
