A Regional Intercomparison of Ice Sheet Mass Balance Estimates of the Northwest Greenland Ice Sheet

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 10, October 2026.
Abstract Changes in ice sheet mass manifest as changes in ice flow, ice thickness, and gravitational attraction. These parameters can be measured from space and used to track Greenland's contribution to sea level rise independently from each other. While an excellent level of agreement between these satellite techniques has been demonstrated at the ice

Erupted Volume During the 2014–2023 Semisopochnoi Unrest and Eruption Constrained by Multi‐Platform InSAR and Volcanic Gas Observations

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 10, October 2026.
Abstract Volcano deformation data provide important constraints on magma dynamics during volcanic unrest and eruptions. From these observations, we can estimate subsurface pressure changes and relate them to volume change in the reservoir. However, because magma and rock are compressible, this volume change cannot be directly equated with eruptive ...

MULTIBASELINE POLARIMETRIC SAR INTERFEROMETRY FOREST HEIGHT INVERSION APPROACHES [PDF]

, 2011
Polarimetric SAR interferometry (Pol-InSAR) is a radar remote sensing technique that is sensitive to the vertical distribution of scattering processes in volumes.

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.

Tectonic Model of the 2021 Haiti Earthquake Based on a Newly‐Formed Strike‐Slip Bypass Fault Across a Paired Restraining‐Releasing Bend

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 10, October 2026.
Abstract On 14 August 2021, the southern peninsula of Haiti was struck by an Mw 7.2 earthquake that killed more than 2,200 people. The 2021 epicenter is located 95 km west of the Mw 7.0 2010 Haiti earthquake and 7 km north of the main, geomorphic trace of the EW‐striking, left‐lateral strike‐slip Enriquillo‐Plantain Garden fault zone (EPGFZ) that forms

Synthetic aperture sonar imaging using compressive sensing and an ultrasound transducer array [PDF]

, 2013
Includes bibliographical references.Compressive sensing (CS) also known as compressive sampling is a technique used to reconstruct or recover the full-length of a signal with only a few non-adaptive measurements.

Microgravity Measurements Spanning 2019–2022 Indicate No Change in Magma Supply or Storage During Kīlauea's Reawakening

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 10, October 2026.
Abstract After more than 2 years of quiescence following its major 2018 flank lava effusion and summit caldera collapse, Kīlauea, Hawaiʻi, returned to frequent eruptive activity in late 2020. Microgravity measurements from the summit region in 2019 and 2022 span this reawakening and indicate a gravity increase of up to hundreds of microgals near the ...

High‐Resolution Body‐Wave Tomography of Kı̄lauea's Summit Magma Storage System From a Dense Passive and Active Source Experiment

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 10, October 2026.
Abstract Imaging magma storage beneath active calderas requires resolving crustal structure at scales comparable to those of individual reservoirs. To identify potential reservoirs beneath Kı̄lauea, Hawai'i, we conducted a hybrid seismic experiment at its summit for 37 days in 2023 that combined more than 1,800 three‐component nodal seismometers with ...

Feature Enhancement of Interferometric Synthetic Aperture Radar Image Formation Using Sparse Bayesian Learning in Joint Sparsity Approach

Leida xuebao, 2018
A novel sparse Bayesian learning approach with a joint sparsity model is proposed for Interferometric Synthetic Aperture Radar (InSAR) image formation to realize the feature enhancements of interferometric phase denoising and speckle reduction.

Tracking Slow‐Moving Landslide Responses to the 2023 Kahramanmaraş Earthquake With InSAR

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 10, October 2026.
Abstract Strong earthquakes can have a dual impact on the slow‐moving landslide budget of a landscape by either triggering new actively deforming hillslopes or stabilizing existing ones. However, their regional‐scale influence on hillslope processes remains poorly understood because of limited observational coverage and the masking effects of long ...
