- Abstract
Lahar is the most important secondary disaster of volcanoes. According to the principle of natural disaster risk, using the natural data and socio-economic statistics of the study area, a risk assessment model for lahar hazards was established using the disaster risk index method, entropy method, and weighted comprehensive evaluation method. The risk zoning map of lahar disaster in Changbai Mountain is obtained, and analyzed the trend of risk over time. The results showed that the risk index of lahar disaster is bigger near the crater, Antu county is the extremely high risk area and Fusong County is the high risk area, the risk index of 5 county-level cities in the study area is positively related to the time.
