A Statewide InSAR Velocity Map for California Produced by a Comprehensive Large Scale Analysis of ARIA Standard Products

Earth and Space Science, Volume 13, Issue 8, August 2026.
Abstract Routine Synthetic Aperture Radar (SAR) acquisitions from the Sentinel‐1 constellation enable monitoring of slow surface deformation (millimeters to centimeters per year), yet consistent and accessible pathways for producing validated, user‐ready velocity products remain limited.

Time series InSAR surface deformation monitoring in extremely difficult area based on track refining control points selection

Zhongguo dizhi zaihai yu fangzhi xuebao, 2021
The extremely difficult area has the characteristics of extremely rugged terrain, complex geographical environment and sparse permanent scatterers. Therefore, an improved SBAS-InSAR technology is designed to monitor the surface deformation. In this paper,

Impact of Heterogeneous Mantle Viscosity on the Glacial Isostatic Adjustment Correction for GRACE(‐FO): Implications for Surface Mass Trends

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 8, August 2026.
Abstract Accurate interpretation of time‐variable gravity from GRACE (‐FO) requires correction for glacial isostatic adjustment (GIA), which has a gravitational signal similar in magnitude to that of contemporary hydrological and cryospheric mass change.

Bayesian Inference of Complex Stress Evolution in Rate‐and‐State Governed Faults Constrained by Seismicity Rate Observations

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 8, August 2026.
Abstract Temporal changes in seismicity rates can be conceptually understood as a response and consequence of stress changes. Dieterich (1994, https://doi.org/10.1029/93JB02581) formalized this relationship using empirically derived rate‐and‐state friction laws, and Heimisson and Segall (2018, https://doi.org/10.1029/2018JB015656) later generalized the

Thaw Subsidence of Ice‐Rich Permafrost Near Umiujaq, Nunavik (Québec), Canada: 20 Years of Monitoring Using Ground‐Based Leveling Methods, LiDAR, and UAV Photogrammetry

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 8, August 2026.
Abstract Differential thaw subsidence is one of the main effects of ice‐rich permafrost degradation, especially in the discontinuous permafrost zone. Although thawing of ice‐rich permafrost can lead to thermokarst, water ponding, and major damage to critical northern infrastructure, thaw subsidence is not often monitored due to the lack of long‐term ...

Double Trouble: Two Active Magma Reservoirs Identified at Masaya Volcano, Nicaragua, Using Satellite Geodesy

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract We analyze and model ground deformation at Masaya volcano, Nicaragua, using Sentinel‐1 Interferometric Synthetic Aperture Radar (InSAR) time series spanning January 2018–February 2024. Time series show the Masaya Central Reservoir (MCR) experienced ∼3 cm of line of sight (LOS) displacement away from the satellite north of the Santiago crater ...
