Understanding Landslide Prediction

Landslide previdention aims to estimate thee probability of a slope failure in a given area over a specific time period. The previdention relies on identifying andd quantifiing factors that influence slope stability. Key factors included:

Traditional approaches - such as determinastic slope stability models (np., infinite slope, limit signibrium) or statistical methods like logistic regression - often assume linear relationships or require detaild parameter estimates.
