    Uncovering deformation processes from surface displacements (2016)
    Elsevier
    Details
    Publication Date: 2021-05-12
    Description: Today, satellite remote sensing has reached a key role in Earth Sciences. In particular, Synthetic ApertureRadar (SAR) sensors and SAR Interferometry (InSAR) techniques are widely used for the study of dynamicprocesses occurring inside our living planet. Over the past 3 decades, InSAR has been applied for mappingtopography and deformation at the Earth’s surface. These maps are widely used in tectonics, seismology,geomorphology, and volcanology, in order to investigate the kinematics and dynamics of crustal faulting,the causes of postseismic and interseismic displacements, the dynamics of gravity driven slope failures,and the deformation associated with subsurface movement of water, hydrocarbons or magmatic fluids.

    SAR and optical remote sensing for urban damage detection and mapping: case studies (2007)
    Details
    Publication Date: 2012-02-03
    Description: Remote sensing techniques have revealed a suitable monitoring tool to provide data useful for disaster studies. They allow the quick detection of damage and building collapses due to earthquakes, especially in remote areas or where the infrastructures are not well developed to ensure the necessary communication exchanges. In particular, Synthetic Aperture Radar (SAR) sensor is widely used in environmental studies due to its characteristics which allow a fairly synoptic view in almost completely weather and time independent conditions. The spatial resolution of satellite optical sensors is rapidly increasing in the last few years, reaching less than 1 meter (IKONOS and QuickBird satellites) and thus becoming a reliable tool for detecting changes of individual buildings. The combined use of optical satellite images, either at medium and high spatial resolution, and SAR data has been investigated. The results concerning the case studies of Bam and Izmit earthquakes are reported in this paper. Moreover, a comparison between the damage assessment obtained by satellite image analysis and ground survey is also shown.

    Space remote sensing for urban damage detection, mapping and mitigation (2007)
    Details
    Publication Date: 2017-04-04
    Description: In the last years the remote sensing techniques have been demonstrated a suitable monitoring tool for providing data useful for disaster mitigation. In particular, in case of strong earthquake, the rapid detection of damaged buildings and infrastructures has assumed an important role for the civil protection rescue activities. Moreover, the damage assessment can help the redevelopment process of the hit area. The Synthetic Aperture Radar (SAR) is widely used in environmental studies thanks to its peculiarities which allow a fairly synoptic view in almost completely weather and time independent conditions. SAR has been revealed a powerful instrument for change detection and damage evaluation purpose. In particular, interferometric features like the InSAR phase coherence and the intensity correlation of multi-look images collected before and after an earthquake have been used in previous works to detect and quantify changes in built-up area. On the other side, optical sensors have also been successfully used for damage estimation. Thanks to the strong increase of their spatial resolution, reaching to less than 1 meter per pixel, the new optical sensors have become reliable systems for detecting changes of single buildings. However, the presence of clouds, shadows, variation in Sun illumination and geometric distortions are critical for this type of sensors and prevent a fully automatic change detection approach. When both optical and SAR are available, a damage classification can also be obtained by combining the two data types, leading to a more reliable result. This work proposes an effective procedure oriented to the damage mapping. From data requirements (satellite images and auxiliary data) to product delivery the chain for damage mapping is described. This latter in order to provide new instruments useful to Civil Protection Departments and Administrations for disaster management.

    Co-seismic surface effects from very high resolution panchromatic images: the case of the 2005 Kashmir (Pakistan) earthquake (2011)
    Details
    Publication Date: 2017-04-04
    Description: The use of Very High Resolution (VHR) satellite panchromatic image is nowadays an effective tool to detect and investigate surface effects of natural disasters. We specifically examined the capabilities of VHR images to analyse earthquake features and detect changes based on the combination of visual inspection and automatic classification tools. In particular, we have used Quickbird (0.6m spatial resolution) images for detecting the three main coseismic surface features: damages, ruptures and landslides. The present approach has been applied to the 8 October 2005, Mw7.6 Kashmir, Pakistan, earthquake. We have focused our study in and around the main urban areas hit by the above earthquake specifically at Muzaffarabad and Balakot towns. The automatic classification techniques provided the best results wherever dealing with the damage to man-made structures and landslides. On the other hand, the visual inspection method demonstrated in addressing the identification of rupture traces and associated features. The synoptic view (concerning landslide, more than 190 millions of pixels have been automatically classified), the spatiotemporal sampling and the fast automatic damage detection using satellite images provided a reliable contribution to the prompt response during natural disaster and for the evaluation of seismic hazard as well.

    Satellite radar and optical remote sensing for earthquake damage detection: results from different case studies (2006)
    Taylor & Francis
    Details
    Publication Date: 2019-03-14
    Description: In case of a seismic event, a fast and draft damage map of the hit urban areas can be very useful, in particular when the epicentre of the earthquake is located in remote regions, or the main communication systems are damaged. Our aim is to analyse the capability of remote sensing techniques for damage detection in urban areas and to explore the combined use of radar (SAR) and optical satellite data. Two case studies have been proposed: Izmit (1999; Turkey) and Bam (2003; Iran). Both areas have been affected by strong earthquakes causing heavy and extended damage in the urban settlements close to the epicentre. Different procedures for damage assessment have been successfully tested, either to perform a pixel by pixel classification or to assess damage within homogeneous extended areas. We have compared change detection capabilities of different features extracted from optical and radar data, and analysed the potential of combining measurements at different frequency ranges. Regarding the Izmit case, SAR features alone have reached 70% of correct classification of damaged areas and 5 m panchromatic optical images have given 82%; the fusion of SAR and optical data raised up to 89% of correct pixel‐to‐pixel classification. The same procedures applied to the Bam test case achieved about 61% of correct classification from SAR alone, 70% from optical data, while data fusion reached 76%. The results of the correlation between satellite remote sensing and ground surveys data have been presented by comparing remotely change detection features averaged within homogeneous blocks of buildings with ground survey data.

    Una metodologia di indagine basata su tecniche NDT per la mitigazione del rischio sismico di beni storici soggetti a tutela (2015)
    AIPND - Associazione Italiana delle Prove Non Distruttive
    Details
    Publication Date: 2021-09-03
    Description: Sommario In questo lavoro viene presentata una metodologia di indagine NDT (acronimo inglese di Non Destructing Testing), basata su tecniche classiche di misura, telerilevamento prossimale e satellitare ad alta risoluzione spaziale, analisi sismogenetiche ed indagini geofisiche, per la mitigazione del rischio sismico di edifici storici monumentali soggetti a tutela. I risultati sperimentali, ottenuti per il caso di studio del complesso monumentale di Sant’Agostino ubicato nella città di Cosenza, dimostrano l’efficacia dell’approccio proposto sia per applicazioni correnti (il monitoraggio materiale e strutturale di un manufatto), sia per applicazioni emergenti (mitigazione del rischio sismico di beni storici).
    Description: Il presente lavoro è finanziato dal Ministero dell'Università, dell'Istruzione e della Ricerca (MIUR) nell'ambito del programma PON R&C 2007-2013 che finanzia al 100% il progetto PON "MASSIMO"-"Monitoraggio in Area Sismica di Sistemi Monumentali"
