Abstract The mechanism that induced the 2019 Changning earthquake sequence is still a subject of debate. discussion focuses on dip angle seismogenic fault, which directly associated with intersection fault and salt well mine. This study employs Interferometric Synthetic Aperture Radar (InSAR) Global Positioning System data to analyze co- postseismic deformation caused by sequence. coseismic slip distribution model constrained geodetic observations, along geometry faults. afterslip also...
SUMMARY On 2020 December 29, the Mw 6.4 Petrinja earthquake hit Kupa Valley region and set a record for largest in northwestern (NW) Croatia. The coseismic surface displacements are well obtained on three pairs of interferometric synthetic aperture radar images from Sentinel-1 satellites. interferograms exhibit ground deformation with maximum line-of-sight displacement 0.4 m. Based field, we investigate both fault geometry slip distribution. results show dextral event peak 3.50 m at depth...
On November 18, 2017, the Mainling Mw 6.5 earthquake occurred on northern Namche Barwa syntaxis and was largest in surrounding areas since Zayu 8.4 1950. Due to inconvenient access severe environment area, motions tectonic structures of most faults remain unclear. Sparsely distributed seismic observation stations make seismogenic fault focal mechanism controversial. We adopt interferometric synthetic aperture radar (InSAR) invert slip distribution this event by defining geometry with...
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...
The present-day tectonic activities on the northeastern margin of Pamir Plateau are mainly E-W oriented extensions, among which Kongur Extensional System (KES) plays an important role in internal expansion Pamir. As largest earthquake since Taxkorgan earthquakes 1895 and 1896, Aketao occurred Muji fault northern portion KES 2016. Since then, trend seismic along has been paid much attention to. Based visco elastic layered lithosphere model, we calculate co-seismic post-seismic stress changes...
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...
SUMMARY The 2022 Har Lake earthquake sequence, which began in January and lasted for ∼70 d, jolted the area, is located western Qilian Shan, northeastern Tibetan Plateau. Two Mw > 5.5 earthquakes occurred during among March 25 5.8 event considered largest recorded area. However, determining seismogenic faults of as well detailed rupture features, difficult due to lack geological data near-field seismological observations. In this study, we use Sentinel-1 synthetic aperture radar (SAR)...

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...
