Summary: Data driven methods such as Machine Learning algorithms are widely used for Landslide Susceptibility Mapping (LSM). The choice of algorithm and sampling strategy play crucial roles in obtaining accurate results. Random Forest, K Nearest Neighbors, and Support Vector Machine algorithms perform better than Naive Bayes and Logistic Regression, with the former three being more sensitive to sampling strategy and data points. Increasing data points leads to better performance for KNN, RF, and SVM algorithms, while NB and LR algorithms are less affected by sampling strategy and data splitting ratio.

Summary: On August 10, 2019, a large landslide caused by typhoon Lekima and heavy rainfall occurred in Yongjia County, Zhejiang, China, resulting in 32 deaths. The landslide was triggered by a combination of rock mass characteristics, wind load, heavy rainfall, and human activities. The presence of roots and cracks in the strongly weathered tuff allowed rainwater to infiltrate rapidly, destabilizing the slope. The landslide movement lasted for about 30 s with a maximum velocity of 21 m/s, generating an air blast and blocking the river, which led to a barrier lake disaster and the submersion of houses in the nearby village.

Summary: The study predicts landscape changes and quantifies the Bayanbulak ecological risk evolution by assessing susceptibility-hazard indices. Results indicate a decline in water, meadow, and marsh areas, with an increase in wetland hazard and susceptibility. Overall, Bayanbulak's ecological risk is slightly evolving, highlighting the need to focus on factors driving land surface temperature increment and implement climate adaptation measures for ecosystem management.
