摘要
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.
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.
