InSAR及其差分技术在仲巴地震中的应用

Application of InSAR and DInSAR to Zhongba Earthquake

  • 摘要: 介绍了InSAR及其差分技术的基本原理,并以发生在2004年7月12日西藏日喀则地区仲巴县与阿里地区之间(北纬30.5°,东经83.4°)的里氏6.7级(中国台网测定)仲巴地震为例,采用已知DEM的二路差分法获取了仲巴地震的同震形变场。采用Okada弹性半空间位错模型反演了该地震的震源参数,得到了震源机制解。结果表明,仲巴地震为以倾滑为主的右旋正断层型地震,断层面走向近乎南北方向。

     

    Abstract: InSAR and differential interferometric synthetic aperture radar(D-InSAR) are generally introduced;Zhongba earthquake which occurred in July 12,2004 between Tibet Xigaze area Zhongba county and the Ngari area(northern latitude 30.5,east longitude 83.4°) with the Lishi magnitude 6.7 is selected as an example to obtain the coseismic deformation field with the two-pass differential interferometric processing method.The Okada elastic half space dislocation model is used to inverse inversion this earthquake's center of origin parameter,to obtain the focal mechanism solution.
