Analysis of Tianchi volcano activity in Changbai Mountain，NE China

Changbaishan volcano is the largest potential eruptive volcano in China.In this paper,seismic activity,horizontal displacement,vertical displacement and the fluid geochemistry data acquiring from Changbaishan Tianchi Volcano Observatory(TVO) in recent years are analyzed.The authors discussed the ability for the Changbaishan volcanic seismic monitoring and active level of Changbaishan volcano in recent years based on the fundamental monitoring results.The results show that Changbaishan volcano has experienced an unrest episode from 2002 to 2005,but its active level recovers to the background now.

A potential flood hazard caused by Tianchi volcano eruption in Changbai Mountain, Northeast China

Geohazards appear to be increasing in frequency globally. it is of necessity to actively manage these natural hazards to minimize loss of life and property. from an early warning perspective, this paper stresses the potential fatal flood hazard represented by the huge volume of water in tianchi lake, the unique geography of changbai mountain, and the limited flood control ability in the upstream of the songhua river. northeast asian countries should keep a watchful eye on the changbai volcano cooperatively, and chinese government especially needs to prepare plans for fighting a flood in advance.
