SEMANTIC INTERPRETATION OF INSAR ESTIMATES USING OPTICAL IMAGES WITH APPLICATION TO URBAN INFRASTRUCTURE MONITORING [PDF]

The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2015
Synthetic aperture radar interferometry (InSAR) has been an established method for long term large area monitoring. Since the launch of meter-resolution spaceborne SAR sensors, the InSAR community has shown that even individual buildings can be monitored

Monitoring Flood Inundation Dynamics From Space

Reviews of Geophysics, Volume 64, Issue 1, March 2026.
Abstract With the increasing intensity and frequency of flood events worldwide, the need for accurate and timely inundation mapping has never been more critical. Large‐scale flood extent estimations are vital for coordinating effective disaster response, facilitating recovery, and building future resilience.

Detecting Morphological Change From DInSAR Data in Ephemeral, Braided, Gravel Bed Rivers. Application to the Ungauged Trionto River, Italy

Water Resources Research, Volume 62, Issue 3, March 2026.
Abstract Estimating morphological change in braided gravel bed rivers is important to determine the geometry of the active part of the braidplain, that is the width of the area where bed material is transported and the number of active branches during a certain time interval.

Co‐Seismic Deformation and Local Stress Evolution of the Philippines Earthquakes in July and October 2022 Revealed by InSAR and GNSS Observations

Earth and Space Science, Volume 13, Issue 2, February 2026.
Abstract On 27 July and 25 October 2022, an Mw 7.0 earthquake and an Mw 6.4 earthquake struck Abra, northwest of Luzon, Philippines, respectively, with a time interval of less than 3 months and a distance of about 16 km. In this research, interferometric synthetic aperture radar (InSAR) was utilized to retrieve the co‐seismic surface deformation field ...

Magma Storage Below Sabancaya Volcano (Southern Peru) Imaged by Broadband Magnetotellurics

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 2, February 2026.
Abstract Sabancaya volcano is one of the most active volcanoes in the Central Andes. Its ongoing eruptive process is accompanied by large‐scale deformation, with activation of the Huambo‐Cabanaconde fault system, marked by intense seismicity over an area of about 50 × 30 km2 ${\mathrm{k}\mathrm{m}}^{2}$.

Deformation analysis of the Lake Urmia causeway (LUC) embankments in northwest Iran: insights from multi-sensor interferometry synthetic aperture radar (InSAR) data and finite element modeling (FEM)

Journal of Geodesy, 2014
This paper presents deformation analysis of Lake Urmia causeway (LUC) embankments in northwest Iran using observations from interferometry synthetic aperture radar (InSAR) and finite element model (FEM) simulation. 58 SAR images including 10 ALOS, 30 Envisat and 18 TerraSAR-X are used to assess settlement of the embankments during 2003–2013.
