Relationship between occurrence of lahar and hydraulic properties of ashfall covered ground in the Arimura River basin of Sakurajima Volcano, Japan

When volcanic ash accumulates on the surface layer of slopes, it decreases the hydraulic conductivity of the ground, which can trigger lahars even due to small rainfall. Understanding the impact of changes in surface conditions on lahar occurrence is crucial for disaster prevention. This study empl...
