book coordinated by Olivier Cavalié and Emmanuel TrouvéLangues : Anglais (eng) Résumé : (auteur) This chapter presents the application of spaceborne synthetic aperture radar (SAR) interferometric techniques to ground surface deformation resulting from human activity. Subsurface anthropogenic activity can also amplify natural subsidence and can even trigger significant earthquakes. Interferometric SAR (InSAR), as a space-based geodetic tool, thus provides interesting imaging capability for the mapping and monitoring of land motion in response to anthropogenic activities. InSAR can be applied during all phases of tunneling projects: before, to identify pre-existing ground movements; during the work; and after the completion of the work for residual deformation monitoring. InSAR also plays a growing role in evaluating water-management practices and in implementing appropriate water-management strategies that may include subsidence mitigation. Spaceborne SAR interferometry can contribute to such monitoring by complementing and partially replacing ground-based measurements. Fluid extraction and cavity excavation are the main anthropogenic sources of subsidence.

[Termes IGN] séismeRésumé : (auteur) On 10 May 2018, an unprecedented long and intense seismic crisis started offshore, east of Mayotte, the easternmost of the Comoros volcanic islands. The population felt hundreds of events. Over the course of 1 yr, 32 earthquakes with magnitude greater than 5 occurred, including the largest event ever recorded in the Comoros (Mw = 5.9 on 15 May 2018). Earthquakes are clustered in space and time. Unusual intense long lasting monochromatic very long period events were also registered. From early July 2018, Global Navigation Satellite System (GNSS) stations and Interferometric Synthetic Aperture Radar (InSAR) registered a large drift, testimony of a large offshore deflation. We describe the onset and the evolution of a large magmatic event thanks to the analysis of the seismicity from the initiation of the crisis through its first year, compared to the ground deformation observation (GNSS and InSAR) and modelling. We discriminate and characterize the initial fracturing phase, the phase of magma intrusion and dyke propagation from depth to the subsurface, and the eruptive phase that starts on 3 July 2018, around 50 d after the first seismic events. The eruption is not terminated 2 yr after its initiation, with the persistence of an unusual seismicity, whose pattern has been similar since summer 2018, including episodic very low frequency events presenting a harmonic oscillation with a period of ∼16 s. From July 2018, the whole Mayotte Island drifted eastward and downward at a slightly increasing rate until reaching a peak in late 2018. At the apex, the mean deformation rate was 224 mm yr−1 eastward and 186 mm yr−1 downward. During 2019, the deformation smoothly decreased and in January 2020, it was less than 20 per cent of its peak value. A deflation model of a magma reservoir buried in a homogenous half space fits well the data. The modelled reservoir is located 45 ± 5 km east of Mayotte, at a depth of 28 ± 3 km and the inferred magma extraction at the apex was ∼94 m3 s−1. The introduction of a small secondary source located beneath Mayotte Island at the same depth as the main one improves the fit by 20 per cent. While the rate of the main source drops by a factor of 5 during 2019, the rate of the secondary source remains stable. This might be a clue of the occurrence of relaxation at depth that may continue for some time after the end of the eruption. According to our model, the total volume extracted from the deep reservoir was ∼2.65 km3 in January 2020. This is the largest offshore volcanic event ever quantitatively documented. This seismo-volcanic crisis is consistent with the trans-tensional regime along Comoros archipelago.

[Termes IGN] Réunion, île de laRésumé : (Auteur) In the study described here, the capability of space-borne high-resolution L-band synthetic aperture radar (SAR) images (ALOS-2/PALSAR2 data in StripMap SM1 mode) for deriving and mapping two components of the deformation of slow landslides has been investigated. The deformation characterization was carried out on the basis of sub-pixel correlation offset tracking techniques and differential SAR interferometry. On the Hell-Bourg landslide (located on La Réunion Island, with displacements up to about 1 m/year), the deformation maps produced performed significantly better than the C-band or lower-resolution SAR data used in previous studies. A comparison was carried out with Global Navigation Satellite System data acquired on the test site. Even with a reduced image set (seven acquisitions), detailed deformation maps and information on deformation evolution during 2014–2016 could be generated. The combination of L-band data and high resolution was the source of the improved performance provided by this new kind of data.

[Termes IGN] surveillance géologiqueRésumé : (auteur) Ground deformation phenomena can occur due to human activity related to underground works (mines, underground network construction) or the injection/extraction of fluids (water, salt, hydrocarbons). These ground movements are usually surveyed by in situ techniques. Differential interferometry of satellite radar images is an alternative and offers complementary measurements to the conventional monitoring methods. Through several examples, this article proposes an overview of application domains and contributions of this remote sensing technique for the detection, mapping and monitoring of such anthropic-due phenomena.

[Termes IGN] mouvement de terrainRésumé : (auteur) This article gives some explanations on the technique of interferometry of radar images: how to use it, which products are obtained and what are the constraints to use it. Since its beginnings in the late 1980s, this method, thanks to the multiplication of acquisitions of radar images, the consideration of different types of pixels and the variable image geometries, knows constant progress to make its use more automatic and more efficient. Here we present some of these advances, which allows us to better identify current and future uses.
