; ; ; ; ; ; ;Ventura, G.; Istituto Nazionale di Geofisica e Vulcanologia, Sezione OV, Napoli, Italia ;Vilardo, G.; Istituto Nazionale di Geofisica e Vulcanologia, Sezione OV, Napoli, Italia ;Bronzino, G.; Istituto Nazionale di Geofisica e Vulcanologia, Sezione OV, Napoli, Italia ;Gabriele, G.; Istituto Nazionale di Geofisica e Vulcanologia, Sezione OV, Napoli, Italia ;Nappi, R.; Istituto Nazionale di Geofisica e Vulcanologia, Sezione OV, Napoli, Italia ;Terranova, C.; Istituto Nazionale di Geofisica e Vulcanologia, Sezione OV, Napoli, Italia; ; ; ; ; The first geomorphological map of the Somma-Vesuvius active volcano is presented. This map includes the volcanic and epivolcanic landforms at a 1:10.000 scale.The map is obtained combining the available geological information with data derived from: (a) Digital Terrain Model (DTM), (b) image analysis of aerial views and interpretation of topographic maps, (c) field surveys. At Somma-Vesuvius, epivolcanic landforms concentrated in the northern and eastern sectors of the volcano. Volcanic landforms characterize the caldera area, the western and the southern sectors, where the most recent (1631-1944) activity occurred.414 249 - PublicationRestrictedContribution of the SISCam Web-based GIS to the seismotectonic study of Campania (Southern Apennines): an example of application to the Sannio-area(2007)

WEB-GIS technologies greatly contribute to both the environmental monitoring and the disaster management of areas affected by high natural risks. Specifically the SISCam system has been developed with the aim of providing easy access and fast diffusion, through Internet technology, of the most significant geological, geophysical, and territorial data relative to the Campania Region. The Sannio area has been selected as our application example because it is among the most active seismic regions in Italy. This portion of the Southern Apennines which was hit by the June 5, 1688 strong earthquake (MW = 6.7, CPTI 1999) and by some low- and moderate-energy seismic sequences (1990–1992, 1997), is characterized by a complex inherited tectonic setting and low-tectonic deformation rates that hide the seismogenic sources position. Since this case study turned out to be complicated, the use of the SIScam WEB-GIS has become indispensable because it allowed us to visualize, integrate and analyze all the data available, in order to obtain an accurate and direct picture of the seismotectonic setting of the area. Moreover, a different approach of data analysis was necessary, due to the lack of up-todate neotectonic and structural data; therefore, the operation of this GIS system enabled us to process and generate some original informative layers, through image analysis, such as new structural lineaments represented on a map of the potential active faults of the area, which has been the final result of our application, as a contribution to new knowledge about the local seismic risk parameters.276 43 - PublicationOpen AccessThe permanent thermal infrared network for the monitoring of hydrothermal activity at the Solfatara and Vesuvius volcanoes(2008-04)

The system implementation was pursued by both acquiring and integrating all the technological instruments necessary to operate an instrumental system constituted by: a network of remote monitoring stations; a transmission system for the image data centralization; a control unit for both the remote stations control and the acquired data processing. The analysis of two-years long series of IR images collected at the Solfatara allowed us to evaluate, in the observation period, the main thermal features of the major fumarole field located in the SE inner slope of the Solfatara crater.223 247 - PublicationOpen AccessMultiple causes of ground deformation in the Napoli metropolitan area (Italy) from integrated Persistent Scatterers DinSAR, geological, hydrological, and urban infrastructure data(2015)
; ; ; ;Terranova, C.; Istituto Nazionale di Geofisica e Vulcanologia, Sezione OV, Napoli, Italia ;Ventura, G.; Istituto Nazionale di Geofisica e Vulcanologia, Sezione Roma1, Roma, Italia ;Vilardo, G.; Istituto Nazionale di Geofisica e Vulcanologia, Sezione OV, Napoli, Italia; ; This study presents a Differential SAR Interferometry (DinSAR) analysis and review of ERS (1992–2001) and Radarsat (2003–2007) data on the city of Napoli (Italy). These data are processed using the Persistent Scatterers Interferometric synthetic aperture radar (PSInSAR) technique and post-processed by statistical selection and filtering with the aimto obtain, by combining ascending and descending geometries, the spatial distribution of the vertical and horizontal (east–west) components of the ground displacement velocity.We identify fivemain areas of subsidence affecting residential districts and strategic infrastructures (transportations and industrial plants). These are: a) Vomero–Arenella district; b) Scudillo–Stella district, c) Municipio Square; d) Garibaldi Square; and e) Poggioreale district. In these areas, the ground deformation rate is between −1.3 and −10.5 mm/yr and varies through time. In particular, in the investigated time period, the subsidence rate (i) persistently increases in the Scudillo–Stella and Poggioreale districts, (ii) abruptly increases in correspondence of underground construction activities (Municipio and Garibaldi squares), and (iii) decreases following the ground deformation style of the Campi Flegrei caldera (Vomero–Arenella district). More restricted areas of subsidence also occur in the northeastern, less urbanized, sectors of the Napoli metropolitan area. The subsidence triggering factors are investigated through a reviewof the available geological geomorphological, hydrological, and urban network information. With respect to other urban contexts, where the cause of subsidence is of natural or anthropogenic origin, Napoli shows a multiple association of triggering factors. These factors are: sub-soil excavations for the construction of transport infrastructures, filling/emptying cycles of large underground water reservoirs, gravity instability related to local morphological factors, raise of the water table with consequent hydrocompaction due to the stop of ground water withdrawal, and re-activation of volcano-tectonic faults associated to the uplift and subsidence phases (bradyseism) of the neighboring, active Campi Flegrei caldera, whose western sector includes a part of the Napoli urban area. We conclude that in a complex urban and geological setting like that of Napoli, ground deformations induced by anthropic and natural processes may coexist and should be monitored for a correct evaluation of the associated hazard and the management of the city planning activities. Finally, the combined review of satellite and geological data available for different urban districts worldwide is essential to identify the sources of ground deformation and analyze the time evolution of the related anthropic and/or natural processes.457 85 - PublicationOpen AccessAnalisi multitemporale (2006-2010) di dati LiDAR da aereo sulla frana attiva di Montaguto (AV)(2011-04)

Napoli ;Ventura, G.; Istituto Nazionale di Geofisica e Vulcanologia, Sezione Roma1, Roma, Italia; ; ; ; Tecniche di monitoraggio Lidar multi temporale sono state sperimentate dalla Nuova Avioriprese S.r.l., azienda del Consorzio AeroSigma S.c.a.r.l., in stretta collaborazione con il Laboratorio di Geomatica e Cartografia (LGC) dell’Osservatorio Vesuviano, Sez. di Napoli dell’Istituto Nazionale di Geofisica e Vulcanologia – INGV, al fine di definire una procedura di monitoraggio delle frane attive basata su dati da Telerilevamento aereo di tipo ottico, termico e Lidar. La frana di Montaguto (AV), attualmente la frana attiva più lunga d’Europa (3.800 Km) che ha recentemente coinvolto importanti infrastrutture di collegamento tra Puglia e Campania con gravi danni economici e sociali, ha rappresentato il caso reale di applicazione della metodologia di monitoraggio aereo. Questo movimento gravitativo del suolo, la cui dinamica ed evoluzione risulta ascrivibile, con le dovute differenze di temperatura e viscosità ad una colata lavica incanalata, è iniziato nel 2004 su terreni agricoli fino ad invadere, nel 2006, il fondovalle del Fiume Cervaro; nel 2010 la frana ha raggiunto la SS 90 e successivamente la linea ferroviaria Caserta Foggia, interrompendo per mesi i collegamenti su uno dei principali assi di trasporto del Meridione. La complessità e l’estensione del fenomeno attivo, la sua velocità di movimento e deformazione, unitamente alle condizioni di elevata esposizione al rischio delle infrastrutture di trasporto presenti, richiedono il supporto di strumenti in grado di poter percepire in modo areale gli spostamenti e le modificazioni in atto con l’obiettivo di prevederne l’evoluzione in termini di dinamica, estensione e volumi potenzialmente interessati Le informazioni estratte dai dati Lidar multi temporali, integrate da dati ottici aerei e da dati cartografici hanno consentito la produzione di utili parametri di studio e monitoraggio del fenomeno franoso, verificando le condizioni di evoluzione dei fenomeno nel tempo e monitorando gli effetti degli interventi di messa in sicurezza e di mitigazione degli eventuali rischi di riattivazione del fenomeno.833 297 - PublicationOpen AccessPS-Insar data analysis: pre-seismic ground deformation in the 2009 L’Aquila earthquake region(2020)
; ; ; ; ; ; ; ; ; The accuracy of the millimetre-scale measurements made so far by the SAR systems, as well as the multi-temporal analysis methodologies, have provided impressive images of surface displacements in areas affected by strong earthquakes, and contributed to constrain the geometric and kinematic features of earthquake generating faults. The multi-temporal analysis of InSAR data is also being acknowledged as promising for the search of earthquake precursors. We have applied the multi-temporal PS-InSAR technique to the detection of pre- to post-seismic ground displacements in the region struck by the normal faulting 2009 L’Aquila earthquake. We have used ERS and ENVISAT PS-data sets from both ascending and descending orbits, covering a 20-year long time span. On the yearly-scale, we have identified a pre-seismic displacement pattern, which consists of opposite vertical motions that have affected the blocks in the hanging wall and footwall of the structure that is recognised as the surface trace of the earthquake-generating fault. In particular, we have highlighted a pre-seismic uplift for 4-5 years followed by subsidence (starting 6-8 months prior to the earthquake) of the hanging wall block, coeval to opposite vertical motions of the footwall block. We suggest that such a displacement pattern may represent an earthquake precursor signal.250 105 - PublicationRestrictedInSAR Permanent Scatterer analysis reveals fault re-activation during inflation and deflation episodes at Campi Flegrei caldera(2010-10)

The PSInSAR analysis, based on SAR data acquired by ERS-1/2 sensors during the 1992–2001 time interval and by the Radarsat sensor during 2003–2007, identifies displacement patterns over wide areas with high spatial resolution. GPS data acquired by the Neapolitan Volcanic Continuous GPS network provide detailed ground velocity information of specific sites. The satellite-derived data allow us to characterize the deformation pattern that affected the Campi Flegrei caldera during two recent subsidence (1992–1999) and uplift (2005– 2006) phases. PSInSAR results show the re-activation of the caldera ring-faults, intra-caldera faults, and eruptive fissures. We discuss the results in the light of the available volcanological, structural and geophysical data and propose a relationship between the structures activated during the recent unrest episodes and those responsible for the recent (b3.8–4 ka) volcanism. The combined interpretation of the collected data show that (a) the caldera consists of two sectors separated by a N–S striking faulting zone and (b) the intra-caldera NW–SE faults and eruptive fissures in the central-eastern sector re-activated during the studied unrest episodes and represent possible pathways for the ascent of magma and/or gas to the surface. In this sector, maximum horizontal strain, recent volcanism (3.8–4 ka), active degassing and seismicity concentrate. The fault re-activation is related to the dynamics of the caldera and not to tectonic stress. The deformation fields of the uplift and subsidence episodes are consistent with hydrothermal processes and degassing from a magmatic reservoir that is significantly smaller than the large (∼40 km3) magma chamber responsible for the caldera formation. We provide evidence that the monitoring of the horizontal and vertical components of deformation improves the identification of active, aseismic faults. Accordingly, we suggest that future ground deformation models should include the re-activation of the detected structures.461 37 - PublicationRestricted4D Monitoring of Active Landslides by Multi-Temporal Airborne LiDAR Data(Springer, 2013-06)

Digital Terrain Models are constructed from data acquired on May 2006, July 2009, April 2010 and June 2010. The spatial distribution of selected morphometric parameters and the statistical analysis of the temporal variations of such parameters allow us to reconstruct the evolution of the landslide. We recognize zones of uplift and subsidence, estimate the volumes of removed or accumulated material, and determine the average rate of vertical and horizontal displacement. We also map the deformations structures and provide new insights on the sliding mechanisms. Zones in which the topographic features change due to handling/removal work are also analyzed. The approach proposed here provides new insight on the use of airborne LiDAR in the surveillance strategies of landslides and other gravity-controlled processes.305 58 - PublicationRestrictedThermal monitoring of hydrothermal activity by permanent infrared automatic stations: Results obtained at Solfatara di Pozzuoli, Campi Flegrei (Italy)(2007-12-28)

After a positive in situ calibration of the IR camera, we analyze 2175 thermal IR images of the same scene from 2004 to 2007. The scene includes a portion of the steam heated hot soils of Solfatara. The experiment was initiated to detect and quantify temperature changes of the shallow thermal structure of a quiescent volcano such as Solfatara over long periods. Ambient temperature results as the main parameter affecting IR temperatures while air humidity and rain control image quality. A geometric correction of the images was necessary to remove the effects of slow movement of the camera. After a suitable correction the images give a reliable and detailed picture of the temperature changes, over the period October 2004 – January 2007, which suggests origin of the changes were linked to anthropogenic activity, vegetation growth and to the increase of the flux of hydrothermal fluids in the area of the hottest fumaroles. Two positive temperature anomalies were registered after the occurrence of two seismic swarms which affected the hydrothermal system of Solfatara in October 2005 and October 2006. It is worth noting that these signs were detected in a system characterized by a low level of activity with respect to systems affected by real volcanic crisis where more spectacular results will be expected. Results of the experiment show that this kind of monitoring system can be a suitable tool for volcanic surveillance.474 298 - PublicationOpen AccessThe permanent thermal infrared network for the monitoring of hydrothermal activity at the Solfatara and Vesuvius volcanoes.(2007)
