Palaeoseismic (?) liquefaction event in late Quaternary lake sediment at Glen Roy, Scotland

Late Quaternary lake sediment deposits from a former ice-dammed lake at Glen Roy, Scotland, contain deformation structures indicative of liquefaction. The distribution of deformation styles reflects a concentric pattern of the degree of liquefaction. A possible fault rupture and several landslides are also observed in the central area. The liquefaction structures, the zonation of the sediment deformation and the association of deformation with landsliding can most simply be interpreted in terms of ground shaking during a major earthquake occurring at the end of the last glacial episode in Scotland (c. 10,000 BP).
