Climate change is increasing extreme rainfall and landslides in mountain regions, raising concerns about accelerated erosion. Our study in Taiwan’s Laonong Basin combined satellite-derived elevation data with local Lidar data to examine how rapidly the landscape is changing. We found that decadal erosion rates are about 5 millimeters per year, similar to geological rates measured over thousands to millions of years. This suggests that sediment produced by storms and landslides is often temporarily stored in valleys as we have found before being transported downstream, helping maintain long-term erosion balance. Our study also identified smaller areas with much higher erosion rates, highlighting localized landslide hazards and demonstrating the value of enhanced elevation differencing data for monitoring landscape change.
This study quantifies geothermal radiative heat flux and heat loss at the Dayoukeng crater, Tatun Volcanic Group, Taiwan, using UAV thermal imagery and Landsat thermal infrared data. While Landsat efficiently captures regional geothermal heat loss, UAV observations resolve fine-scale thermal variability with much higher spatial detail. Both approaches produce comparable geothermal heat loss estimates (210–217 MW), demonstrating their complementary strengths. This work represents the first UAV-based geothermal heat loss assessment at Dayoukeng and provides a valuable framework for geothermal exploration and volcanic monitoring.
