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 ...

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 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

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, 2018SAR 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 ...

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.

Abstract In March 2021 three strong earthquakes with magnitudes (Mw) of 6.3, 6.0, and 5.2 occurred in Thessaly plain, Greece, on 3, 4, and 12 March, respectively. The modeling of all the three sources, by inversion of Interferometric Synthetic Aperture Radar and Global Positioning System data, indicates a northeast–southwest-trending ...

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.Rodrigo Cifuentes-Lobos +2 more

Coseismic Surface Deformation Characteristics of the 1915 M7.0 Sangri Earthquake in Tibet
The spatial distribution and deformation characteristics of coseismic surface rupture zones are fundamental to understanding the rupture behavior of strong earthquakes. They provide critical insights for predicting the extent, scale, and degree of deformation of future events, which is of great significance for assessing the magnitude of potential ...Junxiang Qiao, Haoyue Sun, Xin Wang

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 ...
