Crustal deformation in extensional regimes: Iceland, Nevada and SW Turkey [PDF]
, 1996 In 1991 a 23-point, 30 x 25 km, GPS geodetic network was established in the Hengill ridge-ridge-transform triple junction, SW Iceland. The GPS data were processed using the Bernese V3.2 software.

, 2022 We processed multi-temporal images taken by Sentinel-1 satellite via using the persistent scatterer InSAR (PSInSAR) technique. With the constraints of continuous GNSS data, we estimated 2D (E-W and vertical) postseismic deformation rates for 3 years ...

COSEISMIC DEFORMATION FIELD AND FAULT SLIP DISTRIBUTION OF THE 2015 CHILE Mw8.3 EARTHQUAKE [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2016 On September 16, 2015, a magnitude 8.3 earthquake struck west of Illapel, Chile. We analyzed Sentinel-1A/IW InSAR data on the descending track acquired before and after the Chile Mw8.3 earthquake of 16 September 2015.

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.Abstract Studies of postseismic creep often infer a strong reduction in upper‐mantle viscosity after large earthquakes, yet the microphysical mechanism responsible for this behavior remains subject of debate. Here, we present new gas‐medium apparatus experiments at 1100–1200°C on pre‐dried, annealed Åheim dunite (grain size of 400 μ ${\upmu }$m ...

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.Abstract Geodetic and seismic observations before the 2011 Mw 9.0 Tohoku‐oki earthquake indicate decadal‐scale acceleration of aseismic slip along the northern Japan Trench, but the mechanism remains debated. We show that this transient can be explained by creep‐front propagation that progressively erodes heterogeneously locked asperities.

Geophysical Research Letters, Volume 53, Issue 19, 16 October 2026.Abstract We investigate the role of the elasticity and density of the forearc mantle wedge corner on the stress distribution in the forearc region of subduction zones, using numerical quasi‐2D lithospheric deformation models for the Cascadia, Nankai, NE Japan, and Costa Rica subduction zones. We incorporate the forearc mantle wedge corner as an elastic

Measuring and Modeling Viscoelastic Relaxation of the Lithosphere with Application to the Northern Volcanic Zone, Iceland [PDF]
, 2010 Viscoelastic relaxation of the stress perturbation caused by an earthquake or diking event can produce measurable ground deformation over 100 km away from the source. We consider the role of viscoelastic relaxation in two different contexts.

The postseismic time series of the CMONOC GPS stations following 2015 Gorkha earthquake
, 2022 The postseismic time series of the CMONOC (Crustal Movement Observation Network of China projects) GPS stations resloved by Zhang et al. (2023) in the manuscript of " Weakened Indian lower crust inferred from postseismic deformation of the 2015 Mw 7.8 ...

Afterslip From the 2020 M 6.5 Monte Cristo Range, Nevada Earthquake
Geophysical Research Letters, 2022 We investigate postseismic deformation following the 15 May 2020, Mw 6.5 Monte Cristo Range, Nevada earthquake using geodetic and aftershock data. Seven months of Sentinel 1‐A/B SAR images were used to model deformation as afterslip on two subparallel ...
