Abstract

Abstract:

The Ashikule volcanic group is located in the Ashikule Basin,which is situated about 250km south of Yutian County,Xinjiang. Ashikule volcanic group consists of more than 10 large volcanoes and dozens of small volcanoes. Its present-day activity is unknown due to the extremely high altitude and inclement weather. Based on Envisat ASAR and ALOS PALSAR images,we obtain the land surface deformation field(2003-2010)by using stacking InSAR(Interferometric Synthetic Aperture Radar)and SBAS-InSAR(Small BAseline Subsets-Interferometric Synthetic Aperture Radar)techniques. We also analyze the volcanic activity based on the InSAR-derived deformation field. Our results show that the deformation of Ashikule volcanic group was not obvious before the 2008 Yutian earthquake(2003-2007).However,it showed a large-scale movement towards satellite after the 2008 Yutian earthquake(2008-2010)with largest accumulated displacement of 1cm. We speculate the large-scale movement had nothing to do with volcanic activity,but it was a result of stress adjustment caused by the 2008 Yutian earthquake. Nevertheless,the northmost end of the coseismic rupture showed movement towards east,and also deflated very much with accumulated subsidence of 6cm.

Key words: InSAR, Ashikule volcanic group, land surface deformation, deformation time series

摘要：

新疆于田县以南250km处的阿什库勒盆地内部,坐落着由10余座主火山和数十个子火山组成的阿什库勒火山群。该火山群海拔较高,气候恶劣,现今活动性未知。文中基于Envisat ASAR和ALOS PALSAR卫星影像资料,利用干涉图堆叠技术和短基线集合成孔径雷达干涉测量技术提取了阿什库勒火山群地区2003—2010年的地表形变场,并据此分析了火山的现今活动状态。结果表明,2008年于田地震之前(2003—2007年),阿什库勒火山群地区比较稳定,形变不明显; 2008年于田地震之后(2008—2010年),阿什库勒火山群地区整体有沿雷达视线方向隆升的态势,累积最大约1cm,为震后块体应力调整的结果,并非火山活动引起的地表形变。而于田地震地表同震破裂带北端则显示出了较强的东向水平运动和垂向下沉运动的形变态势,累积最大约6cm。
