Abstract

Glacial debris flows are a common geological hazard in theglacial region of the Tibetan Plateau. This study analyzed the relationship between land surface temperature (LST) and glacial debris flow in the southeastern part of the Tibetan Plateau. LST showed a year-to-year upward trend, which was more pronounced in the glacial region, throughout the study area. After analyzing the causes of eight glacial debris flows, we found that the sudden increase of LST and the long-term high LST in the early period are the main causes besides the rainfall. The results of the study show that LST can be an effective parameter for monitoring and forecasting glacial debris flows.
