[1] We carry out long‐period surface wave centroid moment tensor (CMT) inversions using various global tomographic models and two different forward modeling techniques for 32 large earthquakes previously studied using interferometric synthetic aperture radar (InSAR) data. Since InSAR methods provide an alternative and independent way of locating and characterizing shallow continental earthquake...

The detection of active rock glacier and the quantification of the observed surface movement as well as its temporal change using the D-InSAR method are presented. An average deformation rate of -7.7 mm/35 days in the radar lineof-sight, in the summer of 1992, was estimated. Whereas, the corresponding geodetic measurement, vertical component of 3D flow velocity, was about –8.0 mm/35 days. Addit...

Differential SAR Interferometry (D-InSAR) is an effective tool in monitoring land subsidence because of its greater coverage area and better resolution of height change. A series of Japanese Earth Resources Satallite-1 (JERS-1) images from 1992 to 1998 has been used in monitoring the mine subsidence in the test site of this study, one of the important coal mining areas in China. D-InSAR procedu...

The City of Xian, China, has been experiencing significant land subsidence and ground fissure activities since 1960s, which have brought various severe geohazards including damages to buildings, bridges and other facilities. Monitoring of land subsidence and ground fissure activities can provide useful information for assessing the extent of, and mitigating such geohazards. In order to achieve ...

[1] Analysis and modeling of InSAR data covering the 2008 Reno-Mogul M 4.7 earthquake swarm indicate that the main event was produced by slip on a previously unrecognized strike-slip fault in the Reno basin. Deformation of 0.5– 2.5 cm in radar line-of-sight was produced by the main event and post-seismic slip over an area of more than 150 km. This earthquake is one of the smallest magnitude eve...

Multi-temporal Interferometric Synthetic Aperture Radar (MT-InSAR) technique has proven to be a powerful tool for the monitoring of time-series ground deformations along the line-of-sight (LOS) direction. However, the one-dimensional (1-D) measurements cannot provide comprehensive information for interpreting the related geo-hazards. Recently, a novel method has been proposed to map the three-d...

An L band geosynchronous synthetic aperture radar (GEO SAR) differential interferometry system (D-InSAR) will be obviously impacted by the background ionosphere, which will give rise to relative image shifts and decorrelations of the SAR interferometry (InSAR) pair, and induce the interferometric phase screen errors in interferograms. However, the background ionosphere varies within the long in...

To monitor and detect the events of landslide, rock-fall along the banks of the Yangtze River in the Three Gorges area, the differential INSAR technique with corner reflectors (CR-Based INSAR) might be more effective than the conventional geological, and discrete GPS measurement techniques, conventional D-INSAR, as well as nature persistent scatterers method. Unfortunately, in most places of th...

Differential synthetic aperture radar interferometry (D-InSAR), is a remote sensing technique that could measure earth surface deformation and has gained extensive use along with its development as a technique and subject, from classical to advanced DInSAR. The main principles of both were concisely depicted and the differences and relations between highlighted. Then an introductive review conc...

The mud receiving area is an important sand storage for dredging sea reclamation and sand-dumping in the waterway. sediment accumulation generated process of dumping has impact on surrounding transportation facilities normal use entire area. From 6 August 2021 to 9 May 2022, Sentinel-1A 24-view SLC data covering sludge were used monitor safety around seawall road by InSAR technology. Synthetic ...
