Active interseismic shallow deformation of the Pingting terraces (Longitudinal Valley – Eastern Taiwan) from UAV high-resolution topographic data combined with InSAR time series

Geomatics, Natural Hazards & Risk, 2017
We focus herein on the location, characterization and the quantification of the most active structural feature of Taiwan: the Longitudinal Valley Fault that corresponds to the suture in between the Philippine and Eurasian Plates.

A 3D finite-element mesh for modeling large-scale surface deformation induced by subduction megathrust earthquakes: Application to Chile

Seismica
Megaearthquakes (Mw > 8) cause continental-scale, long-lasting surface deformation, mainly due to viscoelastic relaxation of the asthenosphere. To investigate the links between this deformation and the slip history along subduction interfaces—including ...

Assessing Slip Rates on the Xianshuihe Fault Using InSAR with Emphasis on Phase Unwrapping Error and Atmospheric Delay Corrections

Remote Sensing
Located on the southeastern periphery of the Tibetan Plateau, the Xianshuihe fault (XSHF) is an active left-lateral strike-slip fault renowned for its frequent and intensive seismic activities. This highlights the necessity of employing advanced geodetic

Interseismic deformation in the Nepal Himalaya from GPS data

, 2007
The velocity of interseismic convergence through the Nepal Himalaya - essential parameter in the study of the seismic cycle - is discussed since several years. To constrain this velocity, we have successfully combined geodetic data from campaign GPS surveys, cGPS stations and DORIS stations to determine the plate motion of India and contemporary ...

Overriding Plate Deformation Controls Inferences of Interseismic Coupling Along the Himalayan Megathrust

Journal of Geophysical Research: Solid Earth
AbstractThe seismic hazard along the Himalayan arc remains a focus of discussion due to its huge potential societal impact. Taking advantage of modern, dense geodetic observations, several attempts have been made to provide a clear picture of the present‐day rate of strain accumulation caused by interseismic coupling on the Main Himalayan Thrust (MHT).

A Sequential Quadratic Programming Approach to Coupling‐Bounded Non‐Inertial Earthquake Cycle Kinematics With Distance‐Weighted Eigenmodes

Earth and Space Science
Geologic and geodetic observations provide constraints on tectonic and earthquake cycle kinematics. Block models offer one approach to integrating the effects of plate rotations, elastic strain accumulation, applied basal displacements, internal block ...

An InSAR‐GNSS Velocity Field for Iran

Geophysical Research Letters
We present average ground‐surface velocities and strain rates for the 1.7 million km2 area of Iran, from the joint inversion of InSAR‐derived displacements and GNSS data.

Seismotectonic Setting of the Andes along the Nazca Ridge Subduction Transect: New Insights from Thermal and Finite Element Modelling

Geosciences
The structural evolution of Andean-type orogens is strongly influenced by the geometry of the subducting slab. This study focuses on the flat-slab subduction of the Nazca Ridge and its effects on the South American Plate.
