Monitoring Co-seismic Deformation Fields of Bam Earthquake Using D-InSAR Technique

2009 International Conference on Environmental Science and Information Application Technology, 2009
The Mw=6.5 Bam earthquake, taking place on 26th December 2003 in Iran, caused severe surface deformation. This paper described that it used the differential interferometric SAR (D-InSAR) technique and ENVISAT ASAR data to monitor the Bam co-seismic deformation fields.

A review of empirical orthogonal function (EOF) with an emphasis on the co-seismic crustal deformation analysis

Natural Hazards, 2021
An automatic, transparent, and regular way to investigate and analyze the spatiotemporal variations in a large, unstructured, and high-dimensional data set is highly desirable in almost every area of knowledge. In light of this, the present study concentrates on a versatile spatiotemporal technique, empirical orthogonal function (EOF), and provides a ...

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 ...

Ocean contribution to co-seismic crustal deformation and geoid anomalies: Application to the 2004 December 26 Sumatra–Andaman earthquake

Earth and Planetary Science Letters, 2011
Large earthquakes do not only heavily deform the crust in the vicinity of the fault, they also change the gravity field of the area affected by the earthquake due to mass redistribution in the upper layers of the Earth. Besides that, for sub-oceanic earthquakes deformation of the ocean floor causes relative sea level changes and mass redistribution of ...

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 ...

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.

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

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.

Pre- and co-seismic ground deformations of the 1999 Chi-Chi, Taiwan earthquake, measured with SAR interferometry

Computers & Geosciences, 2004
The 1999 M-w = 7.6 Chi-Chi earthquake was the strongest inland earthquake in Taiwan in the 20th century. Five radar images acquired with the C-band SARs onboard the ERS-1/2 satellites are combined to study the pre- and co-seismic surface deformations in the epicentral area of about 1500 km(2).
