Active Volcanoes of China

China is home to more than a dozen volcanoes that have erupted during the Holocene. Recent activity, such as the eruption of Ashikule in 1951 and unrest of Changbaishan during 2002–05, highlights the potential for future volcanic unrest and eruptions in the country. In 1999, a National Volcano Monitoring Network was established, inaugurating a programme of research and surveillance to understand the history and activity of China's volcanoes. Much progress has been made since, advancing understanding in the areas of geology, geochemistry and geophysics, and supporting hazard mitigation planning. This Special Publication reports the wide-ranging outcomes of this work for the first time to the international community.

Abstract
Northern Hainan Island and the Leizhou Peninsula volcanic fields (Leiqiong), the southernmost continental Cenozoic volcanism in China, cover an area of c. 8000 km2 with 177 volcanoes recognized. Far from the subduction areas, volcanoes in this area provide an ideal opportunity to study the geodynamics of intraplate volcanoes. Here, we review the geochronological and geochemical data of the volcanic rocks in Leiqiong volcanic fields, and discuss their magma sources and geodynamics on the basis of the geological and geophysical observations. Chronological data (34.78–0.01 Ma) show that the volcanic activities started approximately in the Miocene and continued to the...
