Dune Crestline Mapping With Deep Learning Reveals Large‐Scale Dune Patterns in NW China

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract Dune crestlines encode sediment transport dynamics and atmospheric forcing, yet their large‐scale quantification has been constrained by labor‐intensive mapping or limited resolution. Here we develop an attention‐augmented U‐Net model to automatically extract crestlines from ∼1 m resolution satellite imagery.

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.

Supershear Transitions and Bilateral Asymmetric Rupture of the 2025 Sagaing (Myanmar) Earthquake Revealed by Geodetic and Seismic Observations

Geophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract The Sagaing Fault (SF) accommodates major plate motion in Myanmar, yet large earthquakes along it have rarely been captured by modern geodetic and seismic observations. The 2025 Sagaing earthquake generated an exceptionally long rupture (∼535 km), offering a rare opportunity to investigate rupture dynamics along continental transform fault. We

Coseismic Slip and Early Rapid Afterslip of the 2025 MW 7.7 Myanmar Earthquake Constrained by Space‐Based Geodetic Observations

Geophysical Research Letters, Volume 52, Issue 22, 28 November 2025.
Abstract The 2025 destructive Myanmar earthquake ruptured the previously recognized seismic gap along the Sagaing fault, with the longest ever recorded surface ruptures (∼ ${\sim} $500 km). Here, we use SAR and optical images to characterize coseismic and early postseismic deformation of this event.

Slowdown of Dune Migration in East Asia's Inland Deserts: A 35‐Year Response to Wind Stilling

Geophysical Research Letters, Volume 52, Issue 16, 28 August 2025.
Abstract Global terrestrial stilling, the recent decrease in near‐surface wind speeds, has significant environmental impacts, including reduced dust storms and vegetation recovery in East Asia's drylands. However, direct evidence of stilling effects on sand dunes is limited due to the lack of long‐term observational data.

Multi-Sensor Satellite Analysis for Landslide Characterization: A Case of Study from Baipaza, Tajikistan

Remote Sensing
Central Asia, and in particular Tajikistan, is one of the most geologically hazardous areas in the world, particularly in terms of seismicity, floods, and landslides. The majority of landslides that occur in the region are seismically induced.

Multidirectional Dune Dynamics Under Seasonal Winds on Mars

Geophysical Research Letters, Volume 52, Issue 12, 28 June 2025.
Abstract We present a systematic assessment of the complex aeolian bedforms across the western rim of Hellas Planitia, the largest impact basin on Mars. Repeat orbital imaging shows crescentic, transverse, and star dunes across the Hellespontus Montes region migrate, converge, and occasionally reverse course.

Spatial and Temporal Variability of the Surface Mass Balance of Debris‐Covered Glacier Tongues

Journal of Geophysical Research: Earth Surface, Volume 130, Issue 3, March 2025.
Abstract Himalayan glaciers often have a supraglacial debris layer that causes spatial heterogeneity in surface changes and mostly reduces melt. Despite this, debris‐covered glaciers lose mass at similar rates to debris‐free glaciers. Understanding related processes is crucial for assessing impacts on water resources and hazards.
