Interpretation of the coseismic surface deformation of Wenchuan earthquake based on the theory of disclination and dislocation

IOP Conference Series: Materials Science and Engineering, 2019
Abstract A combination model of disclination-dislocation which can describe the three-dimensional translational and rotational motion of the fault is given. We used the combined model and the dislocation model to calculate the coseismic horizontal displacement of 102 points of Wenchuan earthquake respectively.

Three-Dimensional Deformation of the 2023 Turkey Mw 7.8 and Mw 7.7 Earthquake Sequence Obtained by Fusing Optical and SAR Images

Remote Sensing, 2023
In February 2023, Mw 7.8 and Mw 7.7 earthquakes struck southeastern Turkey. Generating a coseismic 3D deformation field that can directly reflect the characteristics of surface deformation is important for revealing the movement mode of a seismogenic ...

Impact of topography and three-dimensional heterogeneity on coseismic deformation [PDF]

, 2019
Knowledge of deformation at plate boundaries has been improved greatly by the development of observational techniques in space geodesy. However, most theoretical and numerical models of coseismic deformation have remained very simple and do not include ...

Slip distributions on active normal faults measured from LiDAR and field mapping of geomorphic offsets: an example from L'Aquila, Italy, and implications for modelling seismic moment release [PDF]

, 2015
Surface slip distributions for an active normal fault in central Italy have been measured using terrestrial laser scanning (TLS), in order to assess the impact of changes in fault orientation and kinematics when modelling subsurface slip distributions ...

Improved SAR Amplitude Image Offset Measurements for Deriving Three-Dimensional Coseismic Displacements [PDF]

, 2015
Offsets of synthetic aperture radar (SAR) images have played an important role in deriving complete three-dimensional (3-D) surface displacement fields in geoscientific applications. However, offset maps often suffer from multiple outliers and patch-like
