Yushu earthquake Co-seismic deformation field extraction based on ALOS/PALSAR data

2011 International Conference on Remote Sensing, Environment and Transportation Engineering, 2011
Synthetic Aperture Radar Interferometry (InSAR) provides an invaluable approach to detect the substantial surface deformation due to the Yushu earthquake (Mw=7.1) on April 14, 2010. The crustal deformation that occurred on April 14, 2010 is recorded by the ALOS satellite in ascending passes. Co-seismic deformation field of Yushu earthquake is extracted

Measuring co-seismic deformation of the Sichuan earthquake by satellite differential INSAR

SPIE Proceedings, 2008
The Sichuan Earthquake, occurred on May 12, 2008, is the strongest earthquake to hit China since the 1976 Tangshan earthquake. The earthquake had a magnitude of M 8.0, and caused surface deformation greater than 3 meters. This paper presents the research work of measuring the co-seismic deformations of the earthquake with satellite differential ...

Co-seismic Deformation and Source Parameters of the Mw6.0 Düzce Earthquake by InSAR

2023
23 November, 2022 Mw 6.0 Düzce Earthquake occurred in the west of the North Anatolian Fault Zone (NAFZ) representing a nascent transform fault between the Eurasian Plate and Anatolian Plate. Well-documented seismic sequence along this fault zone started in the east with the 1939 M7.9 Erzincan Earthquake and migrated westward with M>7 ...

Methods to Study Co-seismic Deformations Detectable by Satellite Gravity Mission GRACE

2005
Co-seismic deformations cannot be compared directly with those observed by gravity satellite missions because of the spatial resolution limit of the missions and the signal attenuation of the gravity field. For this purpose, the conventional dislocation theory for a spherical earth model can be used because it is expressed in the form of a spherical ...

Effect of Thickness of Sediment Layer on the Co‐seismic Deformation

ce/papers
AbstractModels with different thicknesses of sediment layer were developed based on the finite element method and equivalent‐bodyforce approach. Taking the fault information of the 2013 Lushan County Ms 7.0 earthquake as an example, the co‐seismic deformation of the surface under different thicknesses of sediment layer is comparatively analyzed. It was

Co-seismic and ongoing land deformation at Mt. Lyford Village, North Canterbury

2018
The Mw 7.8 2016 Kaikōura earthquake caused considerable damage to land and buildings at Mt Lyford Village, north Canterbury. In light of this event, the Natural Hazards Research Platform (NHRP) along with the Hurunui District Council (HDC) and Environment Canterbury (ECan) have jointly funded a study of the earthquake damage caused to Mt Lyford Village.

Co-seismic deformation following the 2007 Bengkulu earthquake constrained by GRACE and GPS observations

Physics of the Earth and Planetary Interiors, 2018
Abstract Gravity changes caused by giant earthquakes can be detected by Gravity Recovery and Climate Experiment (GRACE), which provide new constraints on earthquake ruptures. However, detailed rupture, seismic moment and density/displacement-induced gravity changes are not clear for less than Mw = 8.5 earthquakes.

Investigating co-seismic deformation of the 2008 Wenchuan earthquake with ALOS SCANSAR interferometric observations

2010 IEEE International Geoscience and Remote Sensing Symposium, 2010
On May 12th, 2008, a destructive earthquake of magnitude 8.0 struck Wenchuan. The seismic region is located at the transition zone between Qinghai-Tibet Plateau and the Sichuan Basin, which has a complex geological tectonic background. In this paper, we intend to investigate the Wenchuan earthquake using the Differential Interferometric SAR(D-InSAR ...

ALOS PALSAR differential interferometry for mapping co-seismic deformation of the 2008 Wenchuan earthquake, China

SPIE Proceedings, 2009
Differential interferometric synthetic aperture radar (DInSAR) technique has been widely accepted as a powerful tool to map surface deformation. To quantitatively evaluate the surface displacement caused by Wenchuan Earthquake on 12 May 2008 in Sichuan Province, China, a series of interferograms were generated from 25 ALOS/PALSAR image pairs, and the ...

Co-seismic surface ruptures in Qiangtang Terrane: Insight into Late Cenozoic deformation of central Tibet

Tectonophysics, 2019
Abstract Recently large earthquakes mostly occurred at the plateau margins along major lithospheric faults. However, a co-seismic rupture has been discovered in central Tibet along the Burgar Co Fault (BGCF), a 150 km-long northwest-trending right-lateral strike-slip fault within the hinterland of the Qiangtang terrane, central Tibet. The activity of
