Abstract
The landslide chronology described here shows temporal discontinuity in mass-movement activity over the last 3,200 radiocarbon years. Three landslides were formed during a period of about three millenia, while four others occurred within a 30-year period. The tree-ring analysis has been a useful dating tool for recent landslide activity. It has provided the exact date and season of landslide occurrence, as well as the short-term climatic context responsible for their inception. The higher landslide frequency recorded in the first part of the nineteenth century was associated with particular climatic conditions (cold and humid). Some landslides occurred during spring, and others during summer. The former were probably induced by snowmelt conditions, and the latter by cool and humid summer conditions. More detailed studies using dendrochronological and archival data could be helpful in determining the seasonal occurrence of a greater number of landslides. On the other hand, landslide dating by the "C technique does not provide enough information on the particular climatic conditions prevailing at the time of landslide activity, unless several dates are used to build reliable mass-movement chronologies which may be compared to existing geomorphic or ecological chronologies. Nevertheless, this dating technique gives the possibility to define the spatio-temporal sequence of landslide development during the Holocene.
