Using a time series method that combines both the persistent scatterer and small baseline approaches, we analyzed 9 scenes Envisat ASAR data over the L＇Aquila earthquake, and obtained a Shocke＇s displacement field and its evolution processes. The results show that：（1） Envisat ASAR clearly detected the whole processes of displacement field of the L＇Aquila earthquake, and distinct variations at different stages of the displacement field. （2） Preseismic creep displacement → displacement mutation when faulting → constantly slowed down after the earthquake. （3） The area of the strongest deformation and ground rupture was a low-lying oval depression region to the southeast. Surface faulting within a zone of about 22 km× 14 km, with an orientation of 135°, occurred along the NW-striking and SW-dipping Paganica-S. Demetrio normal fault. （4） In analyzing an area of about 54 km x 59 km, bounded by north-south axis to the epicenter, the displacement field has significant characteristics of a watershed： westward of the epicenter shows uplift with maximum of 130 mm in line-of-sight （LOS）, and east of the epicenter was a region with 220 mm of maximum subsidence in the LOS, concentrating on the rupture zone, the majority of which formed in the course of faulting and subsequence.

Co- and post-seismic vertical displacements of the Wenchuan earthquake derived from two measurements in 2008 and 2010 along two partly-damaged leveling lines near the epicenter show the following features： Co-seismic displacement at Beichuan-Yingxiu fault was as large as 4. 711 m near Beichuan, where the maximum observed fault offset was 5.1 m. In contrast, the observed co-seismic offset of the Qingchuan fault in Pingwu County was only 0. 064 m. During 2008 - 2010, the post-seismic displacement rate was 5 - 27 mm/a near Beichuan-Yingxiu fault in Beichuan area, 20.6 mrn/a at Jiangyou-Guangyuan fault near Dakang, and only 0.2 - 1.3 mm/a at Qingehuan fault near Gucheng.

The global plate motion rates Ω are not uniform in time and space. The rotation rates were larger than 0. 545°/Ma for Cocos, Philippine Sea, Pacific, Nazca, Australia, India and Arabia plates, but smaller than 0. 315°/Ma. for other plates. Compared to 1997. 0, the Ω values of the three oceanic plates in 2000. 0 increased by,respectively,2.4% ,2. 1% and 41.7%, and the northward movement rates of the the India plate and western part of the Australia plate increased by 3.38 mm/a on the average. The spatial distribution of earthquakes was dependent on earthquake magnitude. Earthquakes of 5.0 ≤ Mw 〈 7.0 were located mainly in plate-margin zones and intra-plate crustal deformation zones joining the southern margin of Eurasia plate. Earthquakes of Mw≥7.0 concentrated basically in the circum-Pacific and South Asia zones, but hardly in midocean-ridge seismic zones. Earthquakes of Mw ≥ 8.0 were located only in the margin zones of the India, Aus- tralia,Pacific and Nazca plates orthogonal to the direction of plate motion. Compared with previous eighteen years, global earthquake activity enhanced obviously after 1994, especially after 2001. The Ω value of a plate was closely related to the activity of strong earthquakes. The largest earthquakes were located in the front-margin zones of plates having the largest Ω values. Energy released by strong earthquakes comes mainly from kinetic energy of the plates. Global seismicity enhancement was caused mainly by the acceleration of the three oceanic plates. Larger enhancement of global earthquake activity lagged behind the movement acceleration of the three oceanic plates by four years.

为提高九寨沟2017-08-08 M_S7.0地震的InSAR同震形变场精度,厘清发震断层的构造形态及形成机制,对形变区相干系数进行统计分析并确定相干性阈值,利用GACOS对形变场进行大气校正,再根据余震分布和地质背景确定发震断层的基本形状,最后基于Okada弹性半空间位错模型反演发震断层的滑动分布。改正后的InSAR同震形变场显示,视线向最大下沉为25 cm,最大抬升为10 cm,分别位于震中西北和东南,形变长轴为北西向,主要形变区位于发震断层西部。改正后的InSAR形变场残差均方根较改正前小,最大滑动量为0.9 m,平均滑动角为-0.5°,破裂主要集中在地下1～20 km范围内,矩震级为6.5,与USGS和GCMT等机构的结果一致。研究表明,利用GACOS改正九寨沟InSAR同震形变场对提高形变场精度具有一定的作用,反演断层滑动分布的结果较改正前差别不明显,发震断层的属性与虎牙断裂北段的性质基本一致。结合余震重定位结果可以推断,发震断层为虎牙断裂的北向延伸部分,此次地震事件为巴颜喀拉地块南东向扭转与华南地块碰撞的结果,中下地壳粘性流体的差异分布是导致虎牙断裂倾角变化的主要原因。

用动态平差与静态平差方法对复测水准网资料进行处理,获得两种方法下高程点的变化量及其速率,对高程点变化量及其速率的分析表明:动态平差可以获取任意时刻地壳运动的动态变化信息,其结果在描述地壳垂直运动特征及其过程时更为合理;而在静态平差结果中,待定点的变化量及其精度、速率值均会因固定点位置的不同而不同,其结果中出现了一个强制约束值,该结果淹没或者转移了观测值中可能包含的形变信息。因此认为,在进行地壳垂直运动分析时,宜采用动态平差计算结果。
