简介：越过在为印度尼西亚地震的印度尼西亚下面的地球结构的S波浪速度通过震动图分析被调查了，同时在时间领域和三个笛卡儿的部件。数据在DAV观察车站被记录，菲律宾。主要数据集合是震动图比较在之间测量并且合成震动图而不是旅行时间数据，当通常在另外的地震学上的研究使用了。合成震动图用GEMINI方法被计算，它在一种古灵长类动物的全球地球披风给背离合成震动图并且更早有的震动图比较表演上面等价于模式Summation.The到达时间比那些测量。在上面的披风层的h的坡度被改变进在一种古灵长类动物模型说了的一个积极，而非否定的斜坡，并且否定修正在所有地球披风层被强加到多项式的系数的零份订单。优秀试穿，以及旅行时间或波形，从爱和瑞利，的表面波浪被获得表面象核心一样向S和SS披风波浪招手地球披风分开的反映的waves.This结果快车，由于在印度和亚洲之间的碰撞构造释放地区，地球披风层在所有在S波浪速度和垂直anisotropy有一个否定异例。

简介：由分析GPS，铺平并且从Minle，Huazangsi和Shagouhe的严肃观察数据在2005期间介绍QilianMountain-Haiyuan差错到对面-2009，这些数据的变化和在不同时间的主要差错的活动特征被获得。Changma-Erbo，Maomaoshan，Zhunglanghe和Haiyuan指责的结果表演在最近的年里是活跃的。在垂直排水量和活动严肃数据之间的关系被分析，并且结果表明严肃变化主要由于集体转移。水平运动速度的方向几乎沿着差错的GPS观察表演的结果在2006罢工-2007当水平速度在2007从差错方向背离了时-2008，由增加的东方排水量描绘了。在连续观察的N和E坐标值的时间系列上的线性趋势的移动之上的进一步的分析在三侧面附近中国的外壳的运动观察网络驻扎表明Wenchuan地震在2007在观察上有效果-2008。在2008比较重力的变化-2009与Bouguer严肃异例背景，我们发现Minle侧面附近的区域在调整和恢复的阶段，当异例完全没在Huazangsi和Shagouhe侧面附近被恢复时。
