Abstract The 2025 MW ${M}_{W}$7.0 Dingri earthquake, which struck southern Tibet on 7 January 2025, provides kinematic insights into extensional tectonics in the region. We use Sentinel‐1 and Lutan‐1 Synthetic Aperture Radar (SAR) data sets to analyze the coseismic displacement fields of this event.

InSAR Modeling of Geophysics Measurements
In the present work, the geometry and basic parameters of interferometric synthetic aperture radar (InSAR) geophysics system are addressed. Equations of pixel height and displacement evaluation are derived. Synthetic aperture radar (SAR) signal model based on linear frequency modulation (LFM) waveform and image reconstruction procedure are suggested ...

Semantic interpretation of InSAR point clouds [PDF]
This paper presents a step towards a better interpretation of the scattering mechanism of different objects and their deformation histories in SAR interferometry (InSAR). The proposed technique traces individual SAR scatterer in high resolution optical images where their geometries, materials, and other properties can be better analyzed and classified.

Abstract The southern San Andreas fault is in its interseismic period, occasionally releasing some stored elastic strain during triggered slow slip events (SSEs) at <2.5 km depth. A distinct, shallowly exhumed gouge defines the fault and is present at SSE depths.

A Multimethod Investigation of the Lake Agnes Rock Glacier, Colorado, USA
ABSTRACT Rock glaciers are important headwater landforms that play a key role in alpine hydrology. North American rock glaciers are estimated to contain the third largest water volume equivalent globally, and over 3800 rock glaciers have been mapped in Colorado alone. However, these features are often overlooked in alpine water budgets.

On the monitoring of surface displacement in connection with volcano reactivation in Tenerife, Canary Islands, using space techniques [PDF]
Geodetic volcano monitoring in Tenerife has mainly focused on the Las Cañadas Caldera, where a geodetic micronetwork and a levelling profile are located.

Improving InSAR geodesy using global atmospheric models [PDF]
Spatial and temporal variations of pressure, temperature and water vapor content in the atmosphere introduce significant confounding delays in Interferometric Synthetic Aperture Radar (InSAR) observations of ground deformation and bias estimatesof ...

ABSTRACT Research in geocryology is currently principally concerned with the effects of climate change on permafrost terrain. The motivations for most of the research are (1) quantification of the anticipated net emissions of CO2 and CH4 from warming and thaw of near‐surface permafrost and (2) mitigation of effects on infrastructure of such warming and

Distribution of slip from 11 M_w > 6 earthquakes in the northern Chile subduction zone [PDF]
We use interferometric synthetic aperture radar, GPS, and teleseismic data to constrain the relative location of coseismic slip from 11 earthquakes on the subduction interface in northern Chile (23°–25°S) between the years 1993 and 2000.
