Short summary
Channelized rock avalanches are a type of rock slope failures with massive flow-like movements of fragmented rock, which are potentially dangerous due to their strong mobility. This study built an empirical prediction model of travel distance using the Wenchuan earthquake dataset. The results suggest that the movement was dominated by the landslide volume, total relief and channel gradient. The model was tested by a separate dataset and proved to be useful in other regions as well.
