Using the measurements of ∼726 GPS stations around Tibetan Plateau, we determine rigid rotation entire plateau in a Eurasia‐fixed reference frame which can be best described by an Euler vector (24.38° ± 0.42°N, 102.37° 0.42°E, 0.7096° 0.0206°/Ma). The rotational component accommodates at least 50% northeastward thrust from India and dominates eastward extrusion northern plateau. After removing to highlight interior deformation within plateau, find that most remarkable is “glacier‐like flow”...
Abstract We process rigorously GPS data observed during the past 25 years from continental China to derive site secular velocities. Analysis of velocity solution leads following results. (a) The deformation field inside Tibetan plateau and Tien Shan is predominantly continuous, large gradients only exist perpendicular Indo‐Eurasian relative plate motion are associated with a few strike‐slip faults. (b) Lateral extrusions occur on both east west sides plateau. westward extrusion peaks at ~6...
We derive a detailed horizontal velocity field for the southeast borderland of Tibetan Plateau using GPS data collected from Crustal Motion Observation Network China between 1998 and 2004. Our results reveal complex deformation that indicates crust is fragmented into tectonic blocks various sizes, separated by strike‐slip transtensional faults. Most notably, regional includes 10–11 mm/yr left slip across Xianshuihe fault, ∼7 Anninghe‐Zemuhe‐Xiaojiang fault zone, ∼2 right shear zone trending...
We collected GPS data from the southern Tarim basin, Qaidam and western Kunlun Shan region between 1993 1998 to determine crustal deformation along Altyn Tagh fault system at northern margin of Tibetan plateau. conclude these that is a left‐lateral strike slip with current rate ∼9 mm/yr, in sharp contrast geological estimates 20–30 mm/yr. This poses an enigma: because cover wider than geologic data, they might be expected reveal somewhat more slip. also find basins behave as rigid blocks...
Abstract Tectonic research of the Tibetan Plateau has long focused on its deformation style and mechanisms. The 2008 Mw7.9 Wenchuan earthquake ruptured Longmen Shan fault located at eastern rim plateau excited a viscoelastic response lithosphere. We infer three‐dimensional (3D) rheological structure Tibet from modeling nine years postseismic displacements observed by GPS. Our solution provides tight constraints lower‐crustal upper‐mantle steady‐state viscosities Songpan‐Ganzi Terrane as (5.0...
Significance The Songpan-Ganzi terrane lies in the central-east of Tibetan Plateau, which was considered a stable block some tectonic models. Its deformation mode is crucial importance for understanding evolutionary history and seismic hazard plateau. recent Maduo earthquake occurred inside terrane. We resolve bilateral rupture process with distinct super- subshear modes this event. also find that pervasive folding structures are aligned by shear current responsible wave anisotropy strain...
Abstract The 20 April 2013 Lushan earthquake occurred on the southern section of Longmen Shan fault system. Using GPS data from 33 continuous stations, we derive a three‐dimensional coseismic displacement field and invert for location, geometry, slip distribution rupture. Our study result indicates that reverse striking N28°E dipping 43° to NW, with maximum located at 30.292°N, 102.943°E, 13 km depth. rupture is dominated by thrust faulting, slight but still statistically significant...
Satellite remote sensing provides a powerful tool for assessing lake water surface temperature (LWST) variations, particularly large bodies that reside in areas. In this study, the MODIS land (LST) product level 3 (MOD11A2) was used to investigate spatiotemporal variation of LWST 56 lakes across Tibetan Plateau and examine factors affecting variations during 2000–2015. The results show annual cycles ranged from −19.5 °C early February 25.1 late July. Obvious diurnal differences (DTDs) were...
The longest total solar eclipse of this century occurred in East and South Asia on 22 July 2009. was accompanied with a medium magnetic storm, whose main phase onset ∼27 min after the passage Moon's umbral shadow. Using TEC data from 60 GPS stations, we construct differential maps to investigate ionosphere response central China range 26°N–36°N, 108°E–118°E (i.e., latitude 15°N–25°N). During eclipse's totality, “shadow” shown as depletion area formed ∼100 km south path maximum decrease 5...
It has been debated for decades whether crustal deformation in and around the Tibetan plateau is distributed or block-like. We model northeastern Tibet using a deformable-block-motion model, which kinematic parameters of block motion internal associated boundary slip rates are inverted GPS velocity data. The F-test used to screen out station outliers, justify independence neighboring blocks, determine significance strains through an iteration process. As result, fifteen blocks identified,...
We revisit the problem of coseismic rupture 2008 Mw7.9 Wenchuan earthquake. Precise determination fault structure and slip distribution provides critical information about mechanical behaviour system earthquake rupture. use all geodetic data available, craft a more realistic Earth model compared to previous studies, employ nonlinear inversion scheme optimally solve for geometry distribution. Compared homogeneous elastic half-space laterally uniform layered models, adopting separate models on...
SUMMARY The 2021 Mw7.4 Maduo earthquake occurred on the Jiangcuo fault within Bayan Har block in eastern Tibet. It is a rather unique event and attests that large earthquakes can occur interior of major tectonic blocks Tibetan plateau. By processing GPS data observed Tibet region, we produce set documenting 3-D coseismic displacements earthquake. Using to constrain slip model, find ruptured nearly vertical about 170 km length, with ∼90% moment released shallow layer above 20 depth. maximum...
Abstract The Pishan, Xinjiang, earthquake on 3 July 2015 is the one of largest events ( M w 6–7) that has occurred along western Kunlun Shan, northwestern edge Tibetan Plateau in recent time. It involved blind thrusting at a shallow depth beneath range front, providing rare chance to gain insights into interaction between Tarim Basin and Plateau. Here we present coseismic ground displacements acquired by high‐resolution ALOS‐2 SAR imagery derived from GPS resurveys several near‐field...
On 12 May 2008 at 06:28 UT a major earthquake of magnitude 8.0 struck Wenchuan County (31.0° N, 103.4° E) in southwest China. Ionospheric total electron content (TEC) values, derived from network 58 global positioning system (GPS) receivers over China and nearby countries, were used to investigate the ionospheric precursor great earthquake. The observations revealed that there was an anomalous enhancement TEC (100% increase on 15-day median) during afternoon–evening sector 9 while...
