| Zusammenfassung |
| The volumes of 4033 landslides have been compiled from 19 different world datasets, taken
both from the literature and from field measurements carried out by the authors. The single
datasets contain various landslide types: rock falls, rock slides, rock avalanches, debris flows,
slides, soil slides and submarine landslides. The range of landslide volumes spans over 18
orders of magnitude, from 10-4 m3 to 1013 m3. The analysis of the volume distribution has
been performed using the kernel density estimator (KDE) tool available in the R statistical
environment. The probability distribution of the landslide volumes is heavy-tailed and is
approximately described by a power law with a negative exponent ranging from -1.9 to
-1.0. The exponent of the power law for each dataset seems to be weakly related
to the landslide type for those datasets presumably complete. In particular, rock
falls and rock slides have exponents higher than those of slides and soil slides. |
