Regions with frequent mudflows
The flow velocity mainly depends on the water percentage and the material; further on the mountain altitude, the mudflow length and its mass. Altogether, the dangerous phenomena occur in different regions:

in alpine countries, especially after heavy rainfalls or when the soil is wet. For instance, after the thaw in spring the soil can easily be detached from the subsurface. Most mudflows begin at steep slopes where the protection by forest may be disturbed, or at the source of a torrent. In the Alps many hundred incidents per year are recorded (all over the world it may be 100 times more) - with an increasing number and damage in the last 20 years.
in arid and semiarid climates when torrential rainfall fails to drain properly and thus causes the nearby rock and dirt to become unstable and to "slide" down a hill or mountain.
at volcanoes, often released by an eruption with simultaneous rainfall. Some disasters of the last decades show: not the size of the volcano or the eruption is the most important parameter, but sometimes rather the coincidence of local slope inclination, special ash sorts, and rainy or thunderstorming weather.
