High‐Resolution Interseismic Strain Mapping From InSAR Phase‐Gradient Stacking: Application to the North Anatolian Fault With Implications for the Non‐Uniform Strain Distribution Related to Coseismic Slip Distribution

Geophysical Research Letters, 2023
High‐resolution interseismic strain mapping is important for studying faulting behavior and for assessing seismic hazards. Interferometric Synthetic Aperture Radar has been widely applied to measure interseismic deformation along active strike‐slip ...

Sensitivity Analysis for Seafloor Geodetic Constraints on Coseismic Slip and Interseismic Slip-Deficit Distributions

Frontiers in Earth Science, 2021
Estimating the coseismic slip distribution and interseismic slip-deficit distribution play an important role in understanding the mechanism of massive earthquakes and predicting the resulting damage.

Parameter estimation for interseismic surface deformation using data assimilation

, 2021
<p>Geodetic data provide an opportunity to improve our understanding of the processes and parameters controlling the dynamics of deformation during the earthquake cycle at subduction zones. However, the observations contain noise and are temporally and spatially sparse, whereas dynamical models are unequivocally imperfect.

The 8 January 2022, Menyuan Earthquake in Qinghai, China: A Representative Event in the Qilian-Haiyuan Fault Zone Observed Using Sentinel-1 SAR Images

Remote Sensing, 2022
On 8 January 2022, a Ms 6.9 earthquake occurred in Menyuan, Qinghai, China. This event provided important geodetic data before and after the earthquake, facilitating the investigation of the slip balance along the seismogenic faults to understand ...

Viscoelastic-cycle model of interseismic deformation in the northwestern United States [PDF]

Geophysical Journal International, 2010
SUMMARY We apply a viscoelastic cycle model to a compilation of GPS velocity fields in order to address the kinematics of deformation in the northwestern United States. A viscoelastic cycle model accounts for time-dependent deformation following large crustal earthquakes and is an alternative to block models for explaining the interseismic crustal ...

Three-dimensional viscoelastic interseismic deformation model for the Cascadia subduction zone [PDF]

Earth, Planets and Space, 2014
Contemporary deformation of the Cascadia forearc consists of an elastic interseismic strain build-up as part of the subduction earthquake deformation “cycle” anda secular deformation primarily in the form ofarc-parallel translation and clockwise rotationofforearc blocks.

Interseismic deformation and geologic evolution of the Death Valley Fault Zone [PDF]

Journal of Geophysical Research: Solid Earth, 2012
The Death Valley Fault Zone (DVFZ), located in southeastern California, is an active fault system with an evolved pull‐apart basin that has been deforming over the past 6 Myr. We present a study of the interseismic motion and long‐term stress accumulation rates to better understand the nature of both past and present‐day loading conditions of the DVFZ.

Constraints on interseismic deformation at Japan Trench from VLBI data

Geophysical Research Letters, 1993
We use space geodetic data from very long baseline interferometry to estimate the velocity relative to the plates of two sites near Tokyo. We use these results and elastic models of interseismic deformation to put constraints on the slip rate along the main thrust at the Japan subduction zone.

Interseismic Deformation and Earthquake Hazard along the Southernmost Longitudinal Valley Fault, Eastern Taiwan [PDF]

Bulletin of the Seismological Society of America, 2012
About half of the 8  cm/yr of oblique convergence across the active convergent plate boundaries of Taiwan occurs in eastern Taiwan, across the Longitudinal Valley. Significant shortening and left‐lateral slip occurs across the Longitudinal Valley fault there, both as shallow fault creep and as seismogenic fault slip.

Determination of Vertical Velocity Field of Southernmost Longitudinal Valley in Eastern Taiwan: A Joint Analysis of Leveling and GPS Measurements

Terrestrial, Atmospheric and Oceanic Sciences, 2012
In order to provide a detailed vertical velocity field in southernmost Longitudinal Valley where shows a complex three-fault system at the plate suture between Philippine Sea plate and Eurasia, we conducted leveling and GPS measurements, compiled data ...
