Unravelling the contribution of early postseismic deformation using sub-daily GNSS positioning. [PDF]

Sci Rep, 2019
AbstractAfter large earthquakes, parts of the fault continue to slip for days to months during the afterslip phase, a behaviour documented for many earthquakes. Yet, little is known about the early stage, i.e., from minutes to hours after the mainshock.

Postseismic deformation following the 1991 Racha, Georgia, earthquake [PDF]

Geophysical Research Letters, 2007
The 1991, Ms = 7.0 Racha earthquake is the largest ever recorded in the Caucasus Mountains. Approximately three months after this thrust‐faulting earthquake, a GPS network was set up to measure postseismic surface deformation. We present an analysis of these data, which indicate accelerated postseismic motions at several near‐field sites. We model this

Realization approach of non-linear postseismic deformation model for Taiwan semi-kinematic reference frame

Earth, Planets and Space, 2020
Surface displacements associated with earthquake-cycle deformation of active faults significantly influence the accuracy of geodetic datum and reference frames, especially for the Taiwan area with high plate convergence and deformation rates.

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

Dizhi 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 ...
