The 3-D surface deformation, coseismic fault slip and after-slip of the 2010 Mw6.9 Yushu earthquake, Tibet, China [PDF]

Journal of Asian Earth Sciences, 2016
Abstract Using SAR interferometry on C band Envisat descending track and L band ALOS ascending track SAR images, respectively, we firstly obtain two coseismic deformation fields and one postseismic deformation of the 2010 Yushu earthquake, Tibet, China.

Coseismic surface deformation caused by the Wenchuan M8 earthquake from InSAR data analysis

2009 IEEE International Geoscience and Remote Sensing Symposium, 2009
The D-InSAR technology is used to aquired seven belts of coseismic surface deformation of Sichuan M8 earthquake of 12 May 2008 from the ALOS/PALSAR satellite data of Japan. The result covers Yinxiu, Dujiangyan, Wenchuan, Moxian, Beichuan, Pingwu and Qingchuan county, each 500km in north-south and 70km in east-west.

Direct estimation of rupture depths of earthquake faults from coseismic surface deformation

Science China Earth Sciences, 2014
The rupture dimensions of earthquake faults are important parameters for characterizing earthquake ruptures and ground motions. Two key parameters to be determined are the rupture depth and dip angle of earthquake faults. Dislocation theory in an elastic half space indicates that if a seismic rupture directly runs up to the ground surface, there exist ...

The surface coseismic deformation and source parameters research of the Xizang Gaize earthquake based on the InSAR technology

Proceedings 2011 IEEE International Conference on Spatial Data Mining and Geographical Knowledge Services, 2011
On 9 January, 2008, the Mw 6.4 earthquake occurred in Gaize, central Tibet of China, then the largest aftershock Mw 5.9 followed on 16th of January. Firstly, we derive the co-seismic deformation field with Synthetic Aperture Radar. The results show an asymmetric deformation pattern both mainshock and aftershock with normal faulting on a NE-striking ...

Refined Coseismic Slip Model and Surface Deformation of the 2021 Maduo Earthquake: Implications for Sensitivity of Rupture Behaviors to Geometric Complexity

Remote Sensing
Geometric complexities of a fault system have a significant impact on the rupture behavior of the fault. The 2021 Mw7.4 Maduo earthquake occurred on a multi-segmented complex sinistral fault in the interior of the Bayan-Har block in the northern Tibetan Plateau.

Coseismic Deformation of the Earth’s Surface in the Area of the Catastrophic 2008 Wenchuan Earthquake According to GPS Measurements

Izvestiya, Atmospheric and Oceanic Physics, 2018
The occurrence time prediction of the strongest earthquakes is one of most topical tasks of seismology. Appearing in the recent years, new observation methods for precursors of different nature can open avenues to achieve success in the field of medium-term seismic forecast. One such method is to observe the Earth’s surface deformation using the Global

The Surface Rupture Zone and Coseismic Deformation Produced by the Yutian Ms7.3 Earthquake of 21 March 2008, Xinjiang

Acta Geologica Sinica, 2012
Abstract:On 21 March 2008, a Ms7.3 earthquake occurred at Quickbird, Yutian County, Xinjiang. We attempt to reveal the features of the causative fault of this shock and its coseismic deformation field. Our work is based on analysis and interpretation to high‐resolution satellite images as well as differential interferometric synthetic aperture radar (D‐

Coseismic Surface Deformations of Global Large Earthquakes in 2014–2016 Detected by Alos-2 Insar

IGARSS 2018 - 2018 IEEE International Geoscience and Remote Sensing Symposium, 2018
SAR interferograms were produced using ALOS-2 data to detect global coseismic deformations associated with large (magnitude ≥ 6) and shallow (depth ≤ 25 km) onshore earthquakes from August 2014 to December 2016. Substantially coherent interferograms were produced for all 30 targeted seismic events, even in tropical areas, where C-band Sentinel-1 ...

Inversion of ocean surface currents to obtain coseismic seafloor deformation.

During an earthquake, the coseismic deformation of the ocean floor is transmitted through the water column. If the earthquake’s energy is sufficiently large, it can uplift the ocean surface, and the subsequent collapse due to gravity leads to the propagation of waves as a tsunami.

The Possibility of Inferring Rupture Depths of Fault Earthquakes from Zero-strain Points of Coseismic Surface Deformation

Seismological Research Letters, 2011
Rupture dimensions of an earthquake fault are important parameters for characterizing the earthquake rupture and studying earthquake mechanics. They have been inferred from aftershock distribution (Alparone and Gambino 2003), seismic reflection and refraction imaging (Minshull and Hall 1997; Catchings et al.
