On August 8, 2017, the Jiuzhaigou Mw 6.5 earthquake occurred in Sichuan province, southwestern China, along eastern margin of Tibetan Plateau. The epicenter is surrounded by Minjiang, Huya, and Tazang Faults. As seismic activity tectonics are very complicated, there controversy regarding accurate location fault earthquake. To investigate these aspects, first, coseismic deformation field was derived from Global Positioning System (GPS) Interferometric Synthetic Aperture Radar (InSAR)...
Abstract On January 19, 2020, an M w 6.0 earthquake occurred in Jiashi, Xinjiang Uygur Autonomous Region of China. The epicenter was located at the basin-mountain boundary between southern Tian Shan and Tarim Basin. Interferometric Synthetic Aperture Radar (InSAR) is used to obtain coseismic deformation field from both ascending descending Sentinel-1A satellite images European Space Agency. results showed that distributed Kalping fault Ozgertaou fault. produced significant over area...
We analyse noise characteristics of spatial and temporal correlation 260 continuous GPS sites from Crustal Movement Observation Network China (CMONOC). These data sets were mainly collected between 2010 2016, with an average 6 yr position time-series. In the functional analysis, a clear regional dependence seasonal movements has been observed other significant periodic signals are detected nearby draconitic period its harmonics. The distribution these shows correlation, along non-negligible...
On September 5, 2022, the Luding M6.8 earthquake occurred in Moxi-Shimian segment of Xianshuihe fault, coinciding with historical ruptured zone 1786 Moxi earthquake. Its seismogenic environment provides a foundation for comprehending mechanism and its future hazard. In segment, we establish series near-field Global Navigation Satellite Systems (GNSS) stations to enhance spatial resolution observational data inversion interseismic kinematic parameters. this study, an elastic screw dislocation...
Abstract The Ning'er Mw 6.1 earthquake on 3 June 2007 occurred in the southwest to Sichuan‐Yunnan rhombic block with complicated seismic structures. focal depth determined by U.S. Geological Survey is only 5 km, but field investigation did not find obvious surface ruptures epicenter area. magnitude obtained inverting broadband waveforms 6.4 that much larger than calculated Survey, indicating this event complicated. Interferometric Synthetic Aperture Radar used study fault geometry, coseismic...
Trimble R7 and Topcon NET-G3A are two common GPS receivers both deployed with choke antenna. But matching antennas different capacity to suppress multipath effect. The research results that for types of receivers, the ability mitigate effect based on P code low satellite elevation cutoff angle is more effective than C/A code. Comparing receiver, mitigation better angle.
The 2020 Mw6.4 Nima earthquake is one of the largest normal-faulting earthquakes recently occurring north Banggong suture zone in remote central Tibet, where geologic investigation active faults extremely limited. We analyze jointly InSAR and GNSS observations over 9 months after calculate coseismic postseismic displacement. optimal slip model suggests this event result moderate-angle down-dip on a complex reversed “S-shape” three-segmented structure at fault junctions West Yibu-Chaka fault,...

Abstract On January 19, 2020, an Mw 6.0 earthquake occurred in Jiashi, Western China. The epicenter was located at the basin-mountain boundary between southern Tian Shan and Tarim Basin. Many strong earthquakes this region, such as 1997 Jiashi swarm. In study, Interferometric Synthetic Aperture Radar (InSAR) used to obtain coseismic deformation field from ascending descending Sentinel-1A satellite data of European Space Agency. results showed that distributed along Kalpingtag fault Ozgertaou...
