In the Tatras maximum thickness of the talus slopes in view of the GPR soundings ranges from 20 to 35 meters.
In the last 200 years, the talus slopes of the Tatras were most active at the end of the LIA, in the 1930s and 1940s, and in the 1970s.
The daily total of rainfall is much less important than the intensity of rainfall.
It can be assumed that with an intensity of 1,0–1,5 mm/min, debris flows may occur about 15 min after precipitation.
