Slope Hazard Monitoring Using High-Resolution Satellite Remote Sensing: Lessons Learned from a Case Study

ISPRS International Journal of Geo-Information, 2020
In this study, a highway slope monitoring project for a section of US highway I-77 in Virginia was carried out with the InSAR technique. This paper attempts to provide insights into the complete and practical solution for the monitoring project ...

Geodetic, teleseismic, and strong motion constraints on slip from recent southern Peru subduction zone earthquakes [PDF]

, 2007
We use seismic and geodetic data both jointly and separately to constrain coseismic slip from the 12 November 1996 M_w 7.7 and 23 June 2001 M_w 8.5 southern Peru subduction zone earthquakes, as well as two large aftershocks following the 2001 earthquake ...

Viscoelastic Relaxation Following the 2001 Mw 8.4 Arequipa Earthquake and Its Impact on the Interseismic Coupling of the South Peru Megathrust

Geophysical Research Letters, Volume 52, Issue 12, 28 June 2025.
Abstract Postseismic displacements associated with the 2001 Mw 8.4 Arequipa earthquake have been observed on a continuous GNSS timeseries in Arequipa for over two decades (∼30 cm on horizontal components). Using Finite Element Method (FEM), we explore the rheological properties of the South Peru subduction zone to model this temporal evolution, and we ...

Landslide Susceptibility Mapping with Integrated SBAS-InSAR Technique: A Case Study of Dongchuan District, Yunnan (China)

Italian National Conference on Sensors, 2022
Landslide susceptibility maps (LSM) are often used by government departments to carry out land use management and planning, which supports decision makers in urban and infrastructure planning. The accuracy of conventional landslide susceptibility maps is

Advanced InSAR atmospheric correction: MERIS/MODIS combination and stacked water vapour models [PDF]

, 2009
A major source of error for repeat-pass Interferometric Synthetic Aperture Radar (InSAR) is the phase delay in radio signal propagation through the atmosphere (especially the part due to tropospheric water vapour).

Inferring Tectonic Plate Rotations From InSAR Time Series

Geophysical Research Letters, Volume 52, Issue 12, 28 June 2025.
Abstract Interferometric Synthetic Aperture Radar (InSAR) provides constraints on lithospheric kinematics at high spatial resolution. Interpreting InSAR‐derived deformation maps at continental scales is challenged by long‐wavelength correlated noise and the inherent limitation of measuring relative displacements within the data footprint.

Phase Unwrapping in InSAR : A Review

IEEE Geoscience and Remote Sensing Magazine, 2019
Synthetic aperture radar (SAR) interferometry (InSAR) is primarily used in remote-sensing applications and has created a new class of radar data that has significantly evolved during the last couple of decades.

Monitoring Subsidence over the Planned Jakarta-Bandung (Indonesia) High-Speed Railway Using Sentinel-1 Multi-Temporal InSAR Data

Remote Sensing, 2022
Investigation of subsidence situations is important for the design of railway lines. Traditional geological investigations are expensive. Multi-temporal InSAR (MT-InSAR) analysis has shown great potential for detecting subsidence areas along large-scale ...

GPS source solution of the 2004 Parkfield earthquake [PDF]

, 2014
We compute a series of finite-source parameter inversions of the fault rupture of the 2004 Parkfield earthquake based on 1 Hz GPS records only. We confirm that some of the co-seismic slip at shallow depth (
