Application of satellite radar interferometry (PSInSAR) in analysis of secondary surface deformations in mining areas. Case studies from Czech Republic and Poland [PDF]

open access: yes, 2018
Secondary deformations are ground movements occurring in areas of ceased underground mining. These are associated with delayed readjustment of rock mass resulting in subsidence, discontinuous deformations (sinks, cracks, etc.) due to destruction of ...

Modelling the Four‐Dimensional Power Line Sag Dynamics by Point Signature in Time‐Series Synthetic‐Aperture Radar Images

open access: yesHigh Voltage, EarlyView.
ABSTRACT Power lines in synthetic‐aperture radar (SAR) images are reflected as point signatures, which fluctuate annually in both the azimuth and range directions. A novel framework is proposed in this paper to evaluate the four‐dimensional dynamic status of power line sag using those point signatures in time‐series SAR images.

The 2009 L' Aquila Earthquake (Central Italy): a source mechanism and implications for seismic hazard [PDF]

open access: yes, 2009
We use InSAR and body-wave seismology to determine independent source\ud parameters for the 6th April 2009 Mw 6.3 L'Aquila earthquake and con¯rm\ud that the earthquake ruptured a SW-dipping normal fault with »0.6{0.8 m\ud slip.

Decoupling Hydroclimatic Controls on Displacement of Retrogressive Thaw Slumps in Qinghai‐Tibet Plateau

open access: yesGeophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract The retrogressive thaw slumps (RTS), a prevalent form of thermokarst hazard in permafrost regions, are increasing in both number and extent under contemporary changing environments. On the Qinghai‐Tibet Plateau, RTS threaten transportation infrastructure and disrupt ecosystems.

Estimating Forest Stand Height in Savannakhet, Lao PDR Using InSAR and Backscatter Methods with L-Band SAR Data

open access: yesRemote Sensing, 2021
Forest stand height (FSH), or average canopy height, serves as an important indicator for forest monitoring. The information provided about above-ground biomass for greenhouse gas emissions reporting and estimating carbon storage is relevant for ...

Buried shallow fault slip from the South Napa earthquake revealed by near-field geodesy. [PDF]

open access: yes, 2017
Earthquake-related fault slip in the upper hundreds of meters of Earths surface has remained largely unstudied because of challenges measuring deformation in the near field of a fault rupture.

Dual Role of a Subducted Seamount in Megathrust Rupture Initiation and Rupture Barrier

open access: yesGeophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract Using high‐resolution 3D tomography and a relocated 2010–2022 earthquake catalog, we identify a seamount at 20–25 km depth beneath the Mompiche–Cojimíes region in the coastal forearc of Ecuador. This provides a rare, well‐resolved example of seamount preservation at these depths. The seamount coincides with a low interseismic‐coupling corridor

Data-driven constraints on earthquake modeling and rupture segmentation from teleseismic multi-array backprojection and InSAR

open access: yes, 2021
Earthquakes have been observed to rupture in segments. A good understanding of rupture segmentation is important to characterize fault geometries at depth for follow-up tectonic, stress-field or ot...

Pre-2014 mudslides at Oso revealed by InSAR and multi-source DEM analysis

open access: yesGeomatics, Natural Hazards & Risk, 2015
The March 22, 2014 Oso mudslide at Washington was an extreme event costing nearly 40 deaths and damaging civilian properties. Historic record indicates that there have been serial events in decades.

Multi-Sensor InSAR Analysis of Progressive Land Subsidence over the Coastal City of Urayasu, Japan

open access: yesRemote Sensing, 2018
In earthquake-prone areas, identifying patterns of ground deformation is important before they become latent risk factors. As one of the severely damaged areas due to the 2011 Tohoku earthquake in Japan, Urayasu City in Chiba Prefecture has been ...
