Debris-flow events at Mt Mangart, Slovenia

In November 2000, following significant rainfall of long duration but relatively low intensity, a sequence of mass movements occurred on the slopes of Mt Mangart in Slovenia. The initial mass movement involved a relatively dry debris flow triggered by a rising water table. The debris-flow deposits filled the local valley, blocking the stream. The deposits gradually became saturated and 2 days later resulted in a secondary (wet) debris flow. This second event was much more mobile, travelling rapidly through steep terrain and leading to the destruction or damage of 29 buildings in the village of Log pod Mangartom and seven fatalities.
