We explored why landslides still happen in areas with dense vegetation. Using data from a mountainous region in China, we combined large-scale mapping with detailed field analysis. We found that while plants can help prevent landslides, their weight and interaction with rainfall and wind can sometimes make slopes more unstable. This research highlights the complex role of vegetation and helps improve landslide prediction and prevention in green mountain areas.

Short summary
The China–Pakistan Economic Corridor plays a vital role in foreign trade and faces threats from water shortage and water-related hazards. An up-to-date glacial lake dataset with critical parameters is basic for water resource and flood risk research, which is absent from the corridor. This study created a glacial lake dataset in 2020 from Landsat and Sentinel images from 1990–2000, using a threshold-based mapping method. Our dataset has the potential to be widely applied.

Short summary
Debris flows after wildfires threaten buildings, but assessing vulnerability remains challenging. This study develops a quantitative model to evaluate building vulnerability to postfire debris flows in Yajiang County. Field surveys and numerical simulations were used to analyze debris flow and quantify intensity. The results highlight differences in vulnerability models compared to previous studies, and provides a systematic framework for risk management strategies in wildfire-affected areas.
