    火山监测研究进展及其对中国火山灾害监测预警工作的启示

    Advances on volcano monitoring and its implications for volcanic hazards monitoring and early warning in China

    • 摘要: 中国及邻区分布着众多的全新世陆相活火山,并留下了大量的喷发历史记录。对这些活火山开展监测和研究工作是预测火山喷发和火山灾害减灾防灾工作的重要途径。高度剥蚀的晚中生代火山区的大量地质填图,以及在活火山区的地球物理、地球化学等近实时的探测工作,极大地深化了我国东部中生代—新生代陆相火山岩的成分特征、岩浆演化规律及喷发方式等方面的认识,是开展火山监测的理想研究对象。近年来,火山灾害日益引起关注,全球火山监测研究进展迅速。本文系统梳理了目前国内外主要的火山监测方法及取得的重要进展,并分析了未来火山灾害减灾防灾工作的发展趋势及我国火山监测工作的发展方向,旨在通过介绍国际火山监测工作,为我国将来开展火山监测、预测与火山灾害相关的减灾防灾等方面的研究和国际合作提供借鉴。

       

      Abstract: A large number of Holocene active volcanoes are distributed in China and adjacent areas, leaving many eruption histories. Monitoring and researching these active volcanoes is a critical process to predict volcanic eruption and respond to volcanic hazards. According to the long-term geological mapping in the Late Mesozoic volcanoes region with deep denudation and the near real-time geophysical and geochemical detection on active volcanic area, the understanding on the composition characteristics, evolution and eruptive style of Mesozoic-Cenozoic continental volcanic rocks in eastern China is significantly enhanced, proving these volcanoes are ideal research objects for continental volcano monitoring. For another, the global volcanic monitoring developed rapidly in recent years with the rising concerns on volcano hazards. In this paper, the main methods and important progress of domestic and overseas continental volcanoes monitoring are systematically reviewed. Furthermore, the development trend of volcanic hazard reduction and prevention in the future, and the development direction of volcano monitoring in China are analyzed. The aim is to provide reference for future research and international cooperation on volcano monitoring, prediction, hazard prevention in China by introducing the work of international volcano monitoring.
