| Summary: | <p dir="ltr">Earthquakes and rainstorms are the most prevalent landslides triggers. However, the characteristic differences between the earthquake- and rainstorm-induced landslides are unclear, which makes it difficult to distinguish the landslide triggers, thus reducing the efficiency of landslide prevention. Here, we collect twelve typical cases of earthquake- and rainstorm-induced landslides from around the world,and quantitatively analyze the geometric characteristics and location distribution of the two types of landslides. We find that earthquake-induced landslides are larger in size and more compact, rounded, and complex in shape than rainstorm-induced landslides. The compactness and major axis of earthquake-induced landslides show a negative correlation in logarithmic function form, while they show a negative correlation in exponential form of rainstorm-induced landslides.Earthquake-induced landslides are predominantly clustered near the ridges, whereas rainstorm-induced landslides are predominantly clustered near the valleys.This experiment indicates that landslides with the same triggers exhibit similar geometric characteristics and location distribution. Our work provides a valuable reference for the classification of landslide triggers and helps to improve the efficiency of landslide prevention and risk assessments.</p> |
