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.

Historical coseismic surface deformation of fluvial gravel deposits, Schafberg fault, Lower Rhine Graben, Germany

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.

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.

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 ...

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

Acta Geologica Sinica - English Edition, 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.

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

Complicated Source Rupture Process and Induced Coseismic Surface Deformation of the Wenchuan Mw 7.9 Earthquake and Their Tectonic Implications

2020
The source rupture processes and coseismic surface rupture of the Wenchuan earthquake are recognized as having the complicated patterns of a great earthquake. In this article, we review some of the Wenchuan earthquake source studies conducted by scientists from Taiwan and mainland China under the scientific cooperation of both sides of the Taiwan ...

Coseismic deformations of the Earth’s surface in Sakhalin related to the August 2, 2007, M w = 6.2 Nevelsk earthquake

Russian Journal of Pacific Geology, 2009
The satellite radiointerferometry data revealed deformations of the coastal part of Sakhalin Island caused by the earthquake with M w = 6.2 that occurred in the Tatar Strait near Nevelsk. Based on the joint analysis of the satellite and seismological data, dislocation models were contrived for the main shock and its strong ...
