Abstract
On March 15, 2024, a wildfire occurred in Yajiang County, Sichuan Province, China, burned an area of 278.8 km2 and influenced 250 catchments in the burned area. On April 23 and May 10–11, 2024, two rainfall events struck the burned area, inducing 8 and 54 post-fire debris flows, respectively. This news investigates the characteristics of the burned area, involving the burn severity mapping, and geometry analysis on the burned catchments. Then, the characteristics of the debris flows following the fire are unravelled based on preliminary field investigations. It is expected that the debris flows after the wildfire, particularly in the first rainy season, with the high susceptibility and low rainfall threshold, will attract researchers’ interest in monitoring and mitigating such unique debris flow disasters.
期刊介绍：
Landslides are gravitational mass movements of rock, debris or earth. They may occur in conjunction with other major natural disasters such as floods, earthquakes and volcanic eruptions. Expanding urbanization and changing land-use practices have increased the incidence of landslide disasters. Landslides as catastrophic events include human injury, loss of life and economic devastation and are studied as part of the fields of earth, water and engineering sciences. The aim of the journal Landslides is to be the common platform for the publication of integrated research on landslide processes, hazards, risk analysis, mitigation, and the protection of our cultural heritage and the environment. The journal publishes research papers, news of recent landslide events and information on the activities of the International Consortium on Landslides.
