利用PALSAR数据研究长白山火山活动性
Estimation of the magma activity of Changbai volcano by PALSAR data
利用2006.10~2011.03期间共24景ALOS卫星的PALSAR数据对长白山天池火山区的近年形变进行了研究，基于PSInSAR方法进行了数据处理，获取了长白山近年火山的时序形变场和形变速率结果。结果表明长白山火山近年火山活动较弱，仅在火山口附近存在10 mm/yr的形变速率。同时利用Mogi模型，对火山区的岩浆变化体积速率进行了反演，显示该区域的岩浆以~1×10 6 m3/a的速率补充。
his paper uses a total of 24 scenes ALOS PALSAR satellite data between 2006.10 and 2011.03 to monitor the deformation for Changbai volcano area in recent years, and based on PSInSAR approach for data processing to obtain the time series and mean rate for deformation in the Changbai volcano regional. The results show that the magma activity for Changbai volcano is weak in recent years, only near the crater there is 10 mm/yr deformation rate. Based on the deformation results, this paper uses Mogi model to inverse the source parameters in volcanic area and the magma volume increased nearly 1×10^6 m^3/a.
