The role of Interferometric Synthetic Aperture Radar in Detecting, Mapping, Monitoring, and Modelling the Volcanic Activity of Piton de la Fournaise, La Réunion: A Review

open access: yesRemote Sensing, 2020
Synthetic Aperture Radar (SAR) remote sensing plays a significant role in volcano monitoring despite the measurements’ non real-time nature. The technique’s capability of imaging the spatial extent of ground motion has especially helped to ...

The worsening impacts of land reclamation assessed with Sentinel-1: The Rize (Turkey) test case [PDF]

open access: yes, 2019
Massive amounts of land are being reclaimed to build airports, new cities, ports, and highways. Hundreds of kilometers are added each year, as coastlines are extended further out to the sea.

Monitoring of a multi‐span prestressed concrete bridge using satellite interferometric data and comparison with on‐site sensor results

open access: yesStructural Concrete, Volume 26, Issue 5, Page 5430-5453, October 2025.
Abstract Satellite‐based Synthetic Aperture Radar Interferometry (InSAR) represents a promising supplement to traditional Structural Health Monitoring (SHM) methods, offering a non‐invasive solution that eliminates the need for sensor installations and provides extensive spatial coverage.

Evidence for postseismic deformation of the lower crust following the 2004 Mw6.0 Parkfield earthquake [PDF]

open access: yes, 2011
Previous studies have shown that postseismic relaxation following the 2004 Mw6.0 Parkfield, CA, earthquake is dominated by afterslip. However, we show that some fraction of the afterslip inferred from kinematic inversion to have occurred immediately ...

Impact of SRTM and ASTER Terrain Models on Geoid Determination: A Case Study in the High‐Mountainous Region

open access: yesEarth and Space Science, Volume 12, Issue 10, October 2025.
Abstract An accurate geoid has important consequences for many fields such as engineering applications, underground resource exploration, geophysical surveys, etc. Its precise determination relies on two key data sets: gravity measurements and high‐resolution elevation data, both of which are critical for achieving reliable results.

Assessment of Mitigation Strategies for Tropospheric Phase Contributions to InSAR Time-Series Datasets over Two Nicaraguan Volcanoes

open access: yesRemote Sensing, 2020
Interferometric Synthetic Aperture Radar (InSAR) studies of ground displacement are often plagued by tropospheric artifacts, which are phase delays resulting from spatiotemporal variations in the refractivity of air within the troposphere. In this study,

Normal fault earthquakes or graviquakes [PDF]

open access: yes, 2015
Earthquakes are dissipation of energy throughout elastic waves. Canonically is the elastic energy accumulated during the interseismic period. However, in crustal extensional settings, gravity is the main energy source for hangingwall fault collapsing ...

The First Three Months of Postseismic Deformation of the 29 July 2021 Mw 8.2 Chignik Earthquake Provides New Constraints on the Down‐Dip Extent of Coseismic Slip

open access: yesJournal of Geophysical Research: Solid Earth, Volume 130, Issue 10, October 2025.
Abstract Stress‐based postseismic deformation modeling including afterslip and viscoelastic relaxation usually assumes the coseismic slip distribution and the associated stress perturbation as known. However, that assumption biases the postseismic modeling results by the assumptions that underlie the coseismic models.

Quantifying Temporal Decorrelation over Boreal Forest at L- and P-band [PDF]

open access: yes, 2008
Temporal decorrelation is probably the most critical factor towards a successful implementation of Pol-InSAR parameter inversion techniques in terms of repeat-pass InSAR scenarios. In this paper the effect and impact of temporal decorrelation at L- and P-
