Land subsidence analysis using synthetic aperture radar data

Heliyon, 2023
Land subsidence is considered a threat to developing cities and is triggered by several natural (geological and seismic) and human (mining, groundwater withdrawal, oil and gas extraction, constructions) factors.

Mass movement susceptibility mapping using satellite optical imagery compared with InSAR monitoring: Zigui County, Three Gorges region, China [PDF]

, 2010
Mass movements on steep slopes are a major hazard to communities and infrastructure in the Three Gorges region, China. Developing susceptibility maps of mass movements is therefore very important in both current and future land use planning.

Integration PS-InSAR and MODIS PWV Data to Monitor Land Subsidence in Semarang City 2015–2018 [PDF]

, 2019
Land Subsidence is a slow on set disaster that can be found in coastal areas such as Semarang City. The cause is changing natural conditions and human activities. The observation method that is often done for this phenomenon is GNSS observation. The GNSS

Reply to Comment by Darwish on “Soaring Building Collapses in Southern Mediterranean Coasts: Hydroclimatic Drivers and Adaptive Landscape Mitigations”

Earth's Future, Volume 14, Issue 3, March 2026.
Abstract We are grateful for Darwish's interest in our paper, Fouad et al. (2025, https://doi.org/10.1029/2024EF004883). In this reply, we show that Fouad et al. (2025, https://doi.org/10.1029/2024EF004883) did not attribute building collapses in Alexandria solely to hydroclimatic factors, as stated in the comment.

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.

Vertical Land Motion and Human Exposure Across India's Coastal Regions

Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract In India, over 200 million people live within 100 km of the coastline, and many reside in low‐lying areas exposed to increasing flood risks associated with sea‐level rise. However, the role of vertical land motion (VLM)—particularly land subsidence—in shaping this coastal exposure remains poorly quantified. Here we present the first assessment
