Deep Learning Applied to Spaceborne SAR Interferometry for Detecting Sinkhole-Induced Land Subsidence Along the Dead Sea

Remote Sensing
The Dead Sea (DS) region has experienced a sharp increase in sinkhole formation in recent years, posing environmental and infrastructure risks. The Geological Survey of Israel (GSI) employs Interferometric Synthetic Aperture Radar (InSAR) to monitor ...

Landslide Activity in the European Alps ‐ Part 1: A Machine Learning Based Instrumental Catalog From the Analysis of Seismological Data

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 4, April 2026.
Abstract Landslides in the European Alps are a growing concern in the context of climate change. However, landslide catalogs for the European Alps remain incomplete, often lacking precise timing and containing few, if any, entries for remote areas.

Hydrometeorological and Topographic Controls on Rock Glacier Kinematics: A Case Study From Southeastern Alaska

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 4, April 2026.
Abstract Rock glacier kinematics are indicators of alpine climate change, yet the relative influence of thermal and hydrological processes on their motion remains poorly constrained. This uncertainty limits our ability to predict how these permafrost landforms will respond to ongoing climate change.

Satellite Monitoring of Railways using Interferometric Synthetic Aperture Radar (InSAR) [Elektronisk resurs]

, 2021
There is over 15,600 km of track in the Swedish railroad network. This network is vital for the transportation of people and goods across the country. It is important that this network is monitored and maintained to ensure good function and safety.

Ellipsoid‐Based Interval‐Type Uncertainty Model Updating Based on Riemannian Manifold and Gaussian Process Model

International Journal of Mechanical System Dynamics, Volume 6, Issue 1, Page 140-152, March 2026.
ABSTRACT Modern engineering systems require advanced uncertainty‐aware model updating methods that address parameter correlations beyond conventional interval analysis. This paper proposes a novel framework integrating Riemannian manifold theory with Gaussian Process Regression (GPR) for systems governed by Symmetric Positive‐Definite (SPD) matrix ...

Stress Barriers and Their Impact on Rupture Propagation

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 2, February 2026.
Abstract Earthquake ruptures often exhibit complex behaviors, including abrupt arrest followed by delayed re‐nucleation. While on‐fault stress heterogeneity is a recognized contributing factor, as it can arrest or slow down rupture propagation, its interaction with propagating ruptures remains complex and not fully understood. Here, we study frictional

Basal Melting Variability of the Ross Ice Shelf From Mixing Ratios of Simulated Water Masses (1993–2018) and Potential Climatic Drivers

Journal of Geophysical Research: Oceans, Volume 131, Issue 2, February 2026.
Abstract Several water masses circulate under the Ross Ice Shelf (RIS), the largest ice shelf in Antarctica, each causing basal melting with a specific spatio‐temporal pattern. To investigate these patterns and their variability, we applied a mixing ratio analysis to simulated water masses from a new numerical ocean model of the Ross Sea.

Effect of Land Cover Type on 3D Deformation Recovery From Synthetically Deformed High Resolution Satellite Optical Imagery

Earth and Space Science, Volume 13, Issue 1, January 2026.
Abstract The limits of detection for earthquake surface deformation in the spatial domain have improved with advances in remote sensing imagery data availability, resolution, and analysis. Sub‐pixel correlation and digital elevation model (DEM) differencing from sub‐meter, earthquake‐spanning satellite optical imagery has enhanced surface rupture ...

Ant-Colony-Based Multiuser Detection for MC DS-CDMA Systems [PDF]

, 2007
In this contribution we present a novel ant colony optimization (ACO) based multi-user detector (MUD) designed for synchronous multi-carrier direct sequence code division multiple access (MC DSCDMA) systems. The operation of the ACO-based MUD is based on
