Abstract

The rainfall climatology of a sample of landslide events in western North Carolina from 1950 to 2004 is presented in 2 parts. First, the two-day concurrent and cumulative antecedent (from 4 to 90 days prior to slope movement) rainfall totals are assessed climatologically by ranking them relative to all heavy precipitation events observed in western North Carolina over a 55-year period. Second, the storm types responsible for the rainfall associated with each landslide event are determined using a manual weather map classification scheme. 47% of the landslide events are connected with concurrent rainfall totals that exceed a one-year return period. In almost half of these cases, the heavy rainfall is associated with a tropical cyclone passing through the region, between 30 and 90 days before the event
