2015 年 4 月 25 日 Mw7.8 尼泊尔地震被中国(CMONOC ) 和尼泊尔测地学的数组(NGA ) 的外壳的运动观察网络成功地记录。我们处理了高率的 GPS 数据(1 ? Hz 并且 5 ? Hz ) 由使用相对的运动学的放和导出的动态地面,运动由这大地震引起了。动态排水量时间系列清楚地显示每个车站的排水量振幅与破裂择向性有关。在破裂繁殖的方向定位了的车站比其它有更大的排水量振幅。超过 5 的另外有活力的地面排水量 ? 厘米由是 2000 的 GPS 车站被检测 ? km 离开震中。永久 coseismic 排水量与小浪分解重建方法从近地的高率的 GPS 车站被解决, P 波浪到达也与 S 变换方法被检测。这研究的结果能被用于地震破裂过程和地震早警告研究。
The April 25, 2015 Mw7.8 Nepal earthquake was successfully recorded by Crustal Movement Observation Network of China (CMONOC) and Nepal Geodetic Array (NGA). We processed the high-rate GPS data (1 Hz and 5 Hz) by using relative kinematic positioning and derived dynamic ground motions caused by this large earthquake. The dynamic displacements time series clearly indicated the displacement amplitude of each station was related to the rupture directivity. The stations which located in the di- rection of rupture propagation had larger displacement amplitudes than others. Also dynamic ground displacement exceeding 5 cm was detected by the GPS station that was 2000 km away from the epicenter. Permanent coseismic displacements were resolved from the near-field high-rate GPS stations with wavelet decomposition-reconstruction method and P-wave arrivals were also detected with S transform method. The results of this study can be used for earthquake rupture process and Earthquake Early Warning studies.
