Simulate landslide activities during flood season 2020 - 2021 in Phong Nha - Ke Bang National Park

During the flood seasons of 2020–21, Phong Nha-Ke Bang National Park experienced significant landslide activity, with the largest event displacing over 130 meters of soil and measuring 2.1 million cubic meters—a figure corroborated by remote sensing data (2.4 million m³). These events, occurring in both core and buffer zones, threatened the park's integrity and aesthetic value, despite its overall stability (gravity displacement coefficients Kg: 0.0006 for core, 0.0033 for buffer). The study identified 60+ landslide points across 81.19 hectares, with volumes ranging from 1,000 to 2.4 million m³, using field monitoring and simulation models. Such findings underscore the vulnerability of this UNESCO World Heritage Site to extreme weather, necessitating further research on mitigation strategies.
