Characterization of Crustal Deformation During the May 2021 Nyiragongo Eruption Using InSAR and GNSS Data

open access: yesGeophysical Research Letters, Volume 53, Issue 1, 16 January 2026.
Abstract We analyze Interferometric Synthetic Aperture Radar (InSAR) and Global Navigation Satellite System (GNSS) data to characterize ground deformation and dike opening associated with the May 2021 Nyiragongo eruption. Despite documented eruptions in 1977 and 2002, Nyiragongo's magmatic system and its interaction with regional rifting remain poorly ...

Geodetic Measurements and Numerical Models of Deformation at Coso Geothermal Field, California, USA, 2004–2016

open access: yesRemote Sensing, 2020
We measure transient deformation at Coso geothermal field using interferometric synthetic aperture radar (InSAR) data acquired between 2004 and 2016 and relative positions estimated from global positioning system (GPS) to quantify relationships between ...

Diagnosis of Xinmo (China) Landslide Based on Interferometric Synthetic Aperture Radar Observation and Modeling

open access: yesRemote Sensing, 2019
The Xinmo landslide occurred on 24 June 2017 and caused huge casualties and property losses. As characteristics of spatiotemporal pre-collapse deformation are a prerequisite for further understanding the collapse mechanism, in this study we applied the ...

Using Sentinel‐1 and Sentinel‐2 to assess the role of soil water content and vegetation cover in mitigating wind erosion in cultivated organic soil

open access: yesVadose Zone Journal, Volume 25, Issue 1, January/February 2026.
Abstract Wind erosion is a major threat to organic soils under intensive agriculture, reducing their productivity and long‐term sustainability. Up to 2.5 cm of soil can be lost in a single storm. This study examined how soil water content and vegetation cover influence wind erosion in cultivated organic soils of the Montérégie region, Quebec, using ...

Earthquake Swarms Triggered by Groundwater Extraction Near the Dead Sea Fault

open access: yesGeophysical Research Letters, 2019
In 2013 and 2018, earthquake swarms with a maximum moment magnitude of 4.5 occurred ~5 km from the northern section of the Dead Sea Transform Fault. Here we show that aquifer pressure data, interferometric synthetic aperture radar surface deformation ...
