Monitoring of Merapi Volcano Deformation Using Interferometry Synthetic Aperture Radar (InSAR) Technique [PDF]
, 2014 The Merapi volcano is the most active volcano in Indonesia until now, because of eruption occur every two or five years. To minimize the impact of volcanic eruptions need to monitor the volcanic activity, one effort in monitoring is to monitor the ...

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 ...

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 1, January 2026.Abstract From 2019 to 2024, gravity surveys were conducted at the Three Sisters volcanic cluster (TSVC), measuring 246 gravity sites using a spring relative gravimeter. We calculated the residual Bouguer anomaly and identified three main zones with negative anomalies, ranging from −4 to −8 mGal, located southwest and west of South Sister, within an ...

InSAR Ground Deformation and Pumping Energy Consumption Reveal Urban Water Security
Water Resources Research, Volume 62, Issue 1, January 2026.Abstract Water resource assessments are critical for ensuring water security (WS), particularly in rapidly urbanizing regions with increasing water demand and limited water monitoring capabilities. Earth observations and indirect indicators of surface and groundwater changes are valuable tools for developing such assessments.
