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 ...

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.

Impact of Ambiguity of Physical Properties of Three-Dimensional Crustal Structure Model on Coseismic Slip and Interseismic Slip Deficit in the Nankai Trough Region

GeoHazards, 2022
Since huge earthquakes are expected along plate subduction zones such as the Japan Trench and Nankai Trough, the estimation of coseismic slip and interseismic slip deficit is essential for immediate response and preliminary measures to reduce damage ...

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.

An asperity model for fault creep and interseismic deformation in northeastern Japan [PDF]

Geophysical Journal International, 2012
We explore the potential geodetic signature of mechanical stress shadows surrounding inferred major seismic asperities along the Japan-Kurile subduction megathrust. Such stress shadows result from a decrease in creep rates late in the interseismic period.

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.

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 ...

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.
