A method for extracting sub-regional deformation of mining subsidence based on SAR technology

Meikuang Anquan, 2022
Aiming at the problem of low applicability of differential interferometric synthetic aperture radar(DInSAR) and offset tracking(OT) technologies in the intersection area of small-scale and large-scale deformation in the edge and center of the subsidence ...

Beyond Rock Glaciers: Investigating Meltwater Contribution and Water Quality in High‐Mountain Springs From Different Landforms

Hydrological Processes, Volume 40, Issue 4, April 2026.
We investigated the water chemistry of springs from different landforms in high‐elevation Alpine catchments. Only in predisposing lithological settings, springs from landforms most likely influenced by ice had a poor water quality with high dissolved concentrations of metals.

Monitoring and early-warning of surface deformation in mine goaf based on InSAR

Meikuang Anquan, 2022
To study the monitoring and early warning ability of DInSAR and SBAS InSAR for mine earthquake collapse in goaf area, this paper uses the two InSAR techniques to process the 11 scene C-band Sentinel-1A SAR images before and after the mine earthquake to ...

Permafrost Terrain Disturbance Susceptibility in the Nacho Nyäk Tagé (Stewart River) Watershed, Yukon, Canada

Permafrost and Periglacial Processes, Volume 37, Issue 2, Page 203-226, April/June 2026.
ABSTRACT The Nacho Nyäk Tagé (Stewart River) watershed in central Yukon (Canada) is characterized by discontinuous permafrost that is locally highly sensitive to thaw. This study aims to map the spatial distribution of permafrost terrain disturbances (PTDs) in the watershed and model thaw susceptibility to support community‐led land‐use planning by the

Identification of Sea Level Rise and Land Subsidence Based on Sentinel 1 Data in the Coastal City of Pekalongan, Central Java, Indonesia

Jurnal Kelautan Tropis, 2023
Sea level rise is a pure impact of climate change. However, the process of studying sea level rise must include local factors that influence such as land subsidence.

Hydrometeorological and Topographic Controls on Rock Glacier Kinematics: A Case Study From Southeastern Alaska

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 4, April 2026.
Abstract Rock glacier kinematics are indicators of alpine climate change, yet the relative influence of thermal and hydrological processes on their motion remains poorly constrained. This uncertainty limits our ability to predict how these permafrost landforms will respond to ongoing climate change.

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.

Coulomb Pre‐Stress Changes Modulate Coseismic Rupture Kinematics of the 2025 Mw7.7 Myanmar Earthquake Revealed by Space Geodesy

Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract We estimate the fault geometry and coseismic slip of the 2025 Myanmar earthquake using multi‐source satellite observations, revealing a nine‐segment rupture structure that transitions from eastward‐dipping in the north to westward‐dipping in the south, with peak slip of ∼6 m and negligible shallow slip deficit.

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 ${\mathrm{k}\mathrm{m}}^{2}$.

Rupture Dynamics of the 2025 Mw 7.7 Myanmar Earthquake: A Bilateral Supershear Rupture on Unusually Long Fault Superhighway

Geophysical Research Letters, Volume 53, Issue 1, 16 January 2026.
Abstract The 2025 Mw 7.7 Myanmar earthquake ruptured the central Sagaing fault, a previously identified seismic gap with high seismic potential. Here, we perform hundreds of 3D dynamic rupture simulations to investigate the rupture dynamics, constrained by near‐fault strong‐motion waveforms, optical and SAR pixel offsets, and a kinematic source model ...
