Interseismic Slip and Coupling along the Haiyuan Fault Zone Constrained by InSAR and GPS Measurements [PDF]

Remote Sensing, 2021
The Haiyuan fault zone is an important tectonic boundary and strong seismic activity belt in northeastern Tibet, but no major earthquake has occurred in the past ∼100 years, since the Haiyuan M8.5 event in 1920.

Interseismic Coupling Along the Java‐Timor Subduction‐Collision Zone at East Indonesia

Geophysical Research Letters
The Java‐Timor subduction‐collision zone is one of the most tectonically complicated structures along the strike of the Indonesia‐Australia convergence. This complexity makes it difficult to interpret observations of interseismic deformation.

Interseismic coupling, segmentation and mechanical behavior of the central Chile subduction zone [PDF]

Journal of Geophysical Research: Solid Earth, 2012
Global Positioning System (GPS) measurements carried out in Chile over the last two decades showed that an entire portion of the Nazca‐South America subduction zone (38°S − 24°S) was locked over this period of time. The induced accumulation of elastic deformation in the upper‐plate was not released until the recent Maule earthquake of 27 February 2010 (

Inferring Interseismic Coupling along the Lesser Antilles Arc: a Bayesian Approach [PDF]

Journal of Geophysical Research: Solid Earth, 2020
AbstractThe Lesser Antilles subduction zone is a challenging region when it comes to unraveling its seismogenic behavior. Over the last century, the subduction megathrust has been seismically quiet, with no large thrust event recorded, which raises the question whether this subduction zone is able to produce large interplate earthquakes or not. However,

Interseismic Plate coupling and strain partitioning in the Northeastern Caribbean [PDF]

Geophysical Journal International, 2008
SUMMARY The northeastern Caribbean provides a natural laboratory to investigate strain partitioning, its causes and its consequences on the stress regime and tectonic evolution of a subduction plate boundary. Here, we use GPS and earthquake slip vector data to produce a present-day kinematic model that accounts for secular block rotation and elastic ...

A Global Set of Subduction Zone Earthquake Scenarios and Recurrence Intervals Inferred From Geodetically Constrained Block Models of Interseismic Coupling Distributions

Geochemistry, Geophysics, Geosystems, 2021
The past 100 years have seen the occurrence of five MW≥9 earthquakes and 94 MW≥8 earthquakes. Here we assess the potential for future great earthquakes using inferences of interseismic subduction zone coupling from a global block model incorporating both

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 ...

Interseismic coupling and refined earthquake potential on the Hayward‐Calaveras fault zone [PDF]

Journal of Geophysical Research: Solid Earth, 2015
AbstractInterseismic strain accumulation and fault creep is usually estimated from GPS and alignment arrays data, which provide precise but spatially sparse measurements. Here we use interferometric synthetic aperture radar to resolve the interseismic deformation associated with the Hayward and Calaveras Faults (HF and CF) in the East San Francisco Bay

Interseismic coupling, stress evolution, and earthquake slip on the Sunda megathrust [PDF]

Geophysical Research Letters, 2013
The extent to which interseismic coupling controls the slip distribution of large megathrust earthquakes is unclear, with some authors proposing that it is the primary control and others suggesting that stress changes from previous earthquakes are of first‐order importance. Here, we develop a detailed stress history of the Sunda megathrust, modified by

Megathrust Slip Behavior for Great Earthquakes Along the Sumatra-Andaman Subduction Zone Mapped From Satellite GOCE Gravity Field Derivatives

Frontiers in Earth Science, 2021
During the last two decades, space geodesy allowed mapping accurately rupture areas, slip distribution, and seismic coupling by obtaining refined inversion models and greatly improving the study of great megathrust earthquakes.
