Numerical simulation of coseismic and postseismic deformation through a node-splitting algorithm: A case study of the Wenchuan earthquake

open access: yesDizhi lixue xuebao, 2021
The coseismic and postseismic effects are crucial elements in analyzing fault interactions and the regional seismic risk. In this paper, we developed a three-dimensional viscoelastic finite element code to simulate the coseismic and postseismic ...

The effects of normal and shear stress wave phasing on coseismic landslide displacement [PDF]

open access: yesJournal of Geophysical Research: Earth Surface, 2015
Predictive models used to assess the magnitude of coseismic landslide strain accumulation inresponse to earthquake ground shaking typically consider slope-parallel ground accelerations only andignore both the influence of coseismic slope-normal ground accelerations and the phase relationshipbetween dynamic slope-normal and slope-parallel accelerations ...

Local interpolation of coseismic displacements measured by InSAR

open access: yesInternational Journal of Applied Earth Observation and Geoinformation, 2013
Abstract Coseismic displacements play a significant role in characterizing earthquake causative faults and understanding earthquake dynamics. They are typically measured from InSAR using pre- and post-earthquake images. The displacement map produced by InSAR may contain missing coseismic values due to the decorrelation of ASAR images.

Coseismic Gravity and Displacement Signatures Induced by the 2013 Okhotsk Mw8.3 Earthquake [PDF]

open access: yesSensors, 2016
In this study, Gravity Recovery and Climate Experiment (GRACE) RL05 data from January 2003 to October 2014 were used to extract the coseismic gravity changes induced by the 24 May 2013 Okhotsk Mw8.3 deep-focus earthquake using the difference and least square fitting methods.

Coseismic surface displacement variability in relation to lithology

open access: yesBulletin of the Geological Society of Greece, 2017
The variability of coseismic surface displacement along reactivated normal faults in the Aegean region is investigated. Seismotectonic data of past earthquakes associated with ground deformation and surface rupturing have been collected and analysed.

Coseismic displacements: 1992 Landers, California, Earthquake

open access: yesGeophysical Research Letters, 1993
The rupture associated with the 1992 Landers earthquake (Ms = 7.5) extended along the west edge of a 60 × 50 km trilateration network that had been surveyed two months before the earthquake and was resurveyed a month after it. The coseismic displacement field within the network was calculated from the changes observed in the trilateration network ...
