Pixel Offset Fusion of SAR and Optical Images for 3-D Coseismic Surface Deformation
IEEE Geoscience and Remote Sensing Letters, 2021This letter presents a 3-D fusion method combining with the pixel offset results of synthetic aperture radar (SAR) and optical images for measuring 3-D coseismic deformation, which suffered the limitations of huge displacement gradient, low coherence, and large temporal interval.

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‐

Historical coseismic surface deformation of fluvial gravel deposits, Schafberg fault, Lower Rhine Graben, Germany [PDF]
International Journal of Earth Sciences, 2017 Intraplate earthquakes pose a significant seismic hazard in densely populated rift systems like the Lower Rhine Graben in Central Europe. While the locations of most faults in this region are well known, constraints on their seismogenic potential and earthquake recurrence are limited.

Abstract The May 12, 2008, Mw 7.9 Wenchuan earthquake occurred along the Longmen Shan fault zone, a thrust fault zone on the eastern margin of Tibet Plateau, and ruptured the ground surface for more than 200 km. A field investigation suggests that the earthquake also ruptured the northern segment (from Beichuan to Qingchuan), along which active ...

Novel Methods for Analyzing Problematic Geodetic Data: Applications to Coseismic Slip Modeling and Surface Deformation Mapping [PDF]
In chapter 2 we describe a novel estimation methodology for estimating coseismic slip models from geodetic observations of coseismic surface deformation. We apply our method to observations from the August 9, 2020, M$_{w}$ 5.1 Sparta, North Carolina earthquake captured by ALOS-2 and Sentinel 1A/B interferograms, along with differential LiDAR.

Coseismic surface deformation caused by the Wenchuan M8 earthquake from InSAR data analysis
2009 IEEE International Geoscience and Remote Sensing Symposium, 2009The 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, 2014The 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 ...
