REVIEW ON THE DEVELOPMENT OF VOLCANIC HAZARD ZONATION IN CHINA

Volcanic hazard evaluation and zonation, as the effective countermeasures, plays an important role in volcanic emergency response and hazard mitigation. Taking Changbaishang volcano as an example, this paper reviews on the study history of volcanic hazard zonation in China. The major types of volcanic hazards in China, which are potentially related with the active volcanoes, involve tephra fallout, pyroclastic flow, lava flow and lahar. The volcanic zoning maps of Changbaishan volcano compiled in 2000 and 2012 respectively show the progresses in volcanic hazard assessment and hazard zonation of China. It is proposed that the probabilistic method such as "event tree" should be applied in compiling the volcanic hazard map of China in future, which represents the most-up-to-date technical trend in volcanic hazard zonation in the world.
