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.
