    Notes: Abstract A priority task for correct environmental planningis to evaluate Natural Hazards, especially inhighly populated areas. In particular, thoroughinvestigations based on different Earth Sciencetechniques must be addressed for the Seismic HazardAssessment (SHA) in tectonically active areas. Notonly the management but also the multidisciplinaryanalysis of all the SHA-related data sets is bestperformed using a Geographic Information System. In this paper we show how a research-oriented GIS isbuilt and used in a practical case. The GeochemicalGeographic Information System (G2IS) wasdeveloped and applied to the Gargano promontory(southern Italy) in the framework of an EC researchproject, the Geochemical Seismic Zonation (GSZ)Project. This multidisciplinary – multiscalingpowerful tool is described in its structure, updatingprocedures and manipulation techniques. Preliminaryresults are presented on the detection of geochemically active fault zones and theircorrelation with remote sensing data and otherevidences of seismogenic structures.

    Investigation of the complex dynamics and structure of the 2010 Eyjafjallajökull volcanic ash cloud using multispectral images and numerical simulations (2013)
    Wiley
    Details
    Publication Date: 2013-03-20
    Description: [1]  We investigated the structure and evolution of the 2010 Eyjafjallajökull volcanic cloud and its dispersal over Iceland and Europe integrating satellite multispectral images and numerical simulations. Data acquired by MERIS and ASTER sensors have been analyzed in order to quantify the cloud extent and composition. The VOL-CALPUFF dispersal code was applied to reconstruct the transient and 3D evolution of the cloud. Source parameters estimated on the base of available a posteriori volcanological data sets have been used. Quantitative comparisons between satellite retrievals and modeling results were performed for two selected instants of time during the first and third eruptive phases on a regional-scale. Sensitivity of the model to initial volcanological conditions has been analyzed at continental-scale. Several complex non-intuitive features of cloud dynamics have been highlighted and strengths and limitations of the adopted methods identified. The main findings are: the level of quantitative agreement between satellite observations and numerical results depends on ash cloud composition (particle sizes and concentration) with better agreement for smaller particles and higher concentrations; the agreement between observations and modeling outcomes also depends on the temporal stability of volcanological conditions and the complexity of the meteorological wind field; the irregular dispersion of ash, as reconstructed from satellite data and numerical modelling, can be well explained by the different response of particle sizes to strong vertical wind-shear, as well as by resuspension processes acting at ground level; eruptive source conditions are the main source of uncertainty in modeling, especially during an ongoing crisis and at long-range scales.

    Correzioni atmosferiche e topografiche di immagini stellitari nell’ambito del progetto sistema rischio vulcanico (2021)
    Details
    Publication Date: 2021-01-14
    Description: Abstract This proposal presents two software procedures built in order to apply atmospheric and topographic corrections to spaceborne satellite images and based on radiative transfer models (6S and MODTRAN) and on DTM (Digital Terrain Model). These procedures are meant to be nested into the chain of the project ASI-Sistema Rischio Vulcanico. The first procedure results from a previous version built for atmospheric and topographic corrections for the VNIR (Visible Near Infrared) in the CIRILLO software. While the second one, for the TIR (Thermal InfraRed) spectral region, is in its testing phase. They are both written in the IDL language (ENVI environment) and they can elaborate images of all principal spaceborne sensors or of customized ones.

    Lava flow thermal analysis using three infrared bands of remote-sensing imagery: a study case from Mount Etna 2001 eruption (2008)
    Elsevier
    Details
    Publication Date: 2017-04-04
    Description: Infrared remotely sensed data can be used to estimate heat flux and thermal features of active volcanoes. The model proposed by Crisp and Baloga (1990) for active lava flows considers the thermal flux as a function of the fractional area of two thermally distinct radiant surfaces: the larger surface area corresponds to the cooler crust of the flow, the smaller one to fractures in the crust. In this model, the crust temperature Tc, the cracks temperature Th, and the fractional area of the hottest component fh represent the three unknowns to solve. The simultaneous solution of the Planck equation (“dual-band” technique) for two distinct shortwave infrared (SWIR) bands allows to estimate any two of the parameters Tc, Th, fh, if the third is assumed. The airborne sensor MIVIS was flown on Mount Etna during the July-August 2001 eruption. This hyperspectral imaging spectrometer offers 72 bands in the SWIR range and 10 bands in thermal infrared (TIR) region of the spectrum, which can be used to solve the dual-band system without any assumption. Therefore, we can combine three spectral MIVIS bands to obtain simultaneous solutions for the three unknowns. Here, the procedure for solving such a system is presented. It is then demonstrated that a TIR channel is required to better pinpoint solutions to the 2-components model. Finally, the spatial and statistical characteristic of the resultant MIVIS-derived temperature and flux distributions are introduced and statistics for each hot spot investigated.

    Una nuova procedura per le correzioni atmosferiche: applicazione sulla Solfatara di Pozzuoli. (2007)
    Details
    Publication Date: 2020-02-24
    Description: This paper describes CIRILLO, a new software for the correction of spaceborne images acquired in the VIS-SWIR spectral range. Moreover the capability to retrieve minerals composing the Solfatara di Pozzuoli surface using ASTER multispectral data is shown. In order to identify the mineralogical composition of the collected sample, mineralogy analysis (X-ray fluorescence and X-ray diffratometry) have been done. The reflectance spectra of the collected sample, obtained using a FieldSpec Pro spectrometer (INAF-LASF) has been compared with measurements performed directly on the Solftara di Pozzuoli using a portable ASD-Fieldspec spectrometer.

    Publication Date: 2020-05-29
    Description: La caldera risorgente dei Campi Flegrei è, insieme ai vulcani Somma-Vesuvio, Ischia e Procida, uno degli elementi dominanti dell’assetto geologico e morfologico dell’area napoletana. Si tratta di un sistema vulcanico ancora attivo la cui persistente attività è testimoniata dall’ultima eruzione, avvenuta nel 1538, dall’intensa attività fumarolica e idrotermale che perdura da millenni e dai frequenti eventi bradisismici, con deformazione del suolo accompagnata da sismicità e variazioni delle caratteristiche chimico-fisiche dei fluidi emessi dalle fumarole. La caldera comprende la parte occidentale della città di Napoli e si estende nel Golfo di Pozzuoli. La caratteristica principale dell’attuale attività vulcanica della caldera è il movimento lento del suolo a carattere episodico e di grande ampiezza (bradisismo), accompagnato da un’intensa e superficiale attività sismica che si verifica in generale durante la fase di sollevamento......

    The March 11th, 2011, M 9.0 earthquake offshore Honshu island (Japan): a synthesis of the Tohoku-Oki INGV Team research activities (2015)
    Details
    Publication Date: 2017-04-04
    Description: On March 11th, 2011 (at 05:46:23 UTC) a megaearthquake (M 9.0) occurred near the NE coast of Honshu island ( Japan), originated near the subduction plate boundary between the Pacific and the North America plates. The epicenter has been located at about 130 km East of Sendai city, at a depth of about 32 km. This seismic event has been followed by a devastating tsunami. The location, the geometric parameters, the focal mechanism, are in agreement with the occurrence of the earthquake along the subduction plate boundary. The initial seismological analysis indicated that a surface of about 300 km x 150 km over the fault moved upwards of 30-40 m. The Tohoku-Oki INGV Team has made available a wide and multisciplinary expertise to investigate the different scientific issues concerning the earthquake. Indeed from Seismology to Geomorphology, from Remote Sensing to GPS, from Tsunami to Source Modeling the INGV Team has completed a wide range of analysis, obtaining relevant outcomes that are summarized in this work.
