Deep Quake Dynamics: A Multimodal Fault‐Aware Approach to Earthquake Magnitude and Occurrence Time Forecasting

Geoscience Data Journal, Volume 13, Issue 2, April 2026.
EQMT integrates earthquake catalog data, fault‐network geometry, engineered features, and graph embeddings in a unified framework for forecasting earthquake magnitude and occurrence time. The framework is designed to reflect inter‐fault spatial dependencies together with temporal seismic patterns, addressing limitations of approaches based only on ...

Frictional Heterogeneity Governs Slip Partitioning and Seismic Hazard in the 2023 Turkey Earthquake Doublet

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract Quantifying fault frictional properties is fundamental to understanding slip behavior and seismic hazard. We analyze 2 years of Sentinel‐1 SAR data following the 2023 Turkey earthquake doublet using Independent Component Analysis‐enhanced Small Baseline Subset‐InSAR, to resolve postseismic deformation and invert for afterslip on the East ...

Retracking considerations in spaceborne GNSS-R altimetry

GPS Solutions, 2012
The European Space Agency Passive Reflectometry and Interferometry System In-orbit Demonstrator (IoD) aims to perform mesoscale altimetric observations by measuring the Global Navigation Satellite System (GNSS) opportunity signals reflected over the sea surface. Altimetry based on GNSS reflectometry (GNSS-R) is significantly

Global Long‐Term Trends in Ionospheric TEC From GNSS Observations With Local‐Time Dependence

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract Long‐term ionospheric changes are expected as a consequence of thermospheric cooling driven by increasing greenhouse gas concentrations. We analyze global ionospheric total electron content (TEC) derived from GNSS observations for 2000–2024 using the high‐resolution ISEE data set.

Upper Mantle Heterogeneity and Weak Subduction Boundaries Control Crustal Stress in the Korean Peninsula

Geophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract Most earthquakes occur at plate boundaries, but some also strike within stable continental interiors. Although dominant causes of such intraplate earthquakes remain elusive, a prevailing hypothesis attributes intraplate stress and seismicity to variations in lithospheric thickness.

Soil moisture retrieval using GNSS-R

, 2009
the UPC Passive Remote Sensing Lab (RSLab) has developed theoretical models exploiting this technique for soil moisture retrieval. These models are based on the interference pattern produced by interaction between the direct GPS signal and the reflected GPS signal coming from the soil surface.
