“…Terranes of Cambrian age and Cretaceous age constitute the basement rocks of this peninsula. Tertiary semi-consolidated sandy clay and Quaternary unconsolidated Interferometric Synthetic Aperture Radar (InSAR), a satellite based technique, offers high precision (cm even to mm), high spatial resolution, and wide coverage measurements of surface deformation, reducing the use of in-situ traditional techniques [5,6]. Furthermore, with the development of the SAR satellite missions, more and more newly acquired TerraSAR, COSMO-SkyMed, Sentinel-1, ALOS-2 and archived SAR data (ERS1/2, JERS-1, ENVISAT, ALOS1) can be used to analyze the spatial-temporal characteristics of large area surface deformation with the temporal InSAR technique [7].…”

Abstract:Over the past two decades, the Leizhou Peninsula has suffered from many geological hazards and great property losses caused by land subsidence. However, the absence of a deformation map of the whole peninsula has impeded the government in making the necessary decisions concerning hazard prevention and mitigation. This study aims to provide the evolution of land deformation (subsidence and uplift) in the whole peninsula from 1992 to 2010. A modified stacking procedure is proposed to map the surface deformation with JERS, ENVISAT, and ALOS1 images. The map shows that the land subsidence mainly occurs along the coastline with a maximum velocity of 32 mm/year and in a wide range of inland arable lands with a velocity between 10 and 19 mm/year. Our study suggests that there is a direct correlation between the subsidence and the surface geology. Besides, the observed subsidence in urban areas, caused by groundwater overexploitation for domestic and industrial use, is moving from urban areas to suburban areas. In nonurban areas, groundwater extraction for aquaculture and arable land irrigation are the main reason for land subsidence, which accelerates saltwater intrusion and coastline erosion if regular surface deformation measurements and appropriate management measures are not taken.

“…The deformation in the LA test site is composed of strong periodical and long-term vertical displacement, which is triggered by both tectonic and hydrogeological sources, e.g., displacement from fault zones and ground water usage [27,48,[51][52][53]. The Okmok test site has a dominant deformation source from the underlying volcanic pressure system [54][55][56], but also contains localized surface subsidence in a limited region inside the caldera due to the contraction of a lava flow post-emplacement [54,57].…”

“…Given the previously suggested strong periodical ground deformation in the Los Angeles Basin [27,48,[51][52][53]65], a temporal evolution model consisting of periodic and linear functions has been used in G-TimeFun and G-NSBAS modules. To demonstrate the results, the total displacement fields for the period 1995-2000 generated by the four SBI approaches are shown in Figure 6.…”

Abstract:The small Baseline Synthetic Aperture Radar (SAR) Interferometry (SBI) technique has been widely and successfully applied in various ground deformation monitoring applications. Over the last decade, a variety of SBI algorithms have been developed based on the same fundamental concepts. Recently developed SBI toolboxes provide an open environment for researchers to apply different SBI methods for various purposes. However, there has been no thorough discussion that compares the particular characteristics of different SBI methods and their corresponding performance in ground deformation reconstruction. Thus, two SBI toolboxes that implement a total of four SBI algorithms were selected for comparison. This study discusses and summarizes the main differences, pros and cons of these four SBI implementations, which could help users to choose a suitable SBI method for their specific application. The study focuses on exploring the suitability of each SBI module under various data set conditions, including small/large number of interferograms, the presence or absence of larger time gaps, urban/vegetation ground coverage, and temporally regular/irregular ground displacement with multiple spatial scales. Within this paper we discuss the corresponding theoretical background of each SBI method. We present a performance analysis of these SBI modules based on two real data sets characterized by different environmental and surface deformation conditions. The study shows that all four SBI processors are capable of generating similar ground deformation results when the data set has sufficient temporal sampling and a stable ground backscatter mechanism like urban area. Strengths and limitations of different SBI processors were analyzed based on data set configuration and environmental conditions and are summarized in this paper to guide future users of SBI techniques.

“…Zhang et al [26] developed an algorithm by constructing a local Delaunay triangulation network. In this algorithm, the temporarily coherent point (TCP) which remains reflectivity only for some time spans is used, and the TCPs in a regular patch are connected and some regular patches are placed over the image.…”

This article focuses on reviewing the technologies of persistent scatterer interferometry (PSI), which has been often used to monitor the deformation of Earth surface. Three critical steps in the implementation of PSI were introduced, i.e., (1) detection of persistent scatterer (PS), (2) construction of PS network, and (3) PSI modeling and solution. Finally, the main problems and outlooks on the PSI technique are discussed and given.
