- PublicationOpen AccessImproving natural risk management by means of virtual surveys through hazardous volcanic contexts by using Augmented and Virtual Reality(EGU, 2019-04-07)
; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; To ensure an efficient natural risk management, we need an in-depth understanding and assessment of risk as well as the adoption of effective prevention measures. Modern techniques such as Augmented Reality (AR) and Virtual Reality (VR) offer the opportunity to explore our environment for professional as well as educational purposes, conveying useful information not only to scientists, but also to at-risk populations. “Virtual navigation on volcanoes by Augmented Reality and 3D-headset” was a geoevent we organized in the framework of the 6th edition of the Italian “Settimana del Pianeta Terra” (Week of Planet Earth) in October 2018. The geoevent featured AR and Virtual Reality exhibits, highlighting the benefits of these tools in applications for Earth monitoring, also with positive contributions in mitigation actions to reduce the impact of natural hazards. We proposed virtual 3D models of volcanic regions in Iceland and Italy (at Etna volcano), which guided the visitors in a virtual survey through hazardous contexts like landslide prone areas and fault zones. The event was supported as part of the 3DTeLC project funded through the Erasmus+ Key Action 2 Strategic Partnerships for Higher Education scheme (Project Reference: 2017-1-UK01-KA203-036719).106 39 - PublicationRestrictedThe 2002–03 Etna explosive activity: Tephra dispersal and features of the deposits(2008-04-23)

Etna’s 2002–03 eruption was marked by intense explosive activity beginning on 27 October 2002 and persisting until 30 December. This phase of activity produced abundant ash emission that impacted the local economy and air traffic. Thereafter, explosive activity declined with the eruption ceasing on 28 January 2003. In this paper, we present field data collected during the eruption and use these to obtain input data for tephra dispersal model. This was applied, after validation, to extrapolate the total distribution of the deposits emplaced during the explosive activity. Detailed sampling of fallout deposits was completed on 27, 28, 31 October and 4 November. This enabled construction of isomass maps and calculation of the erupted mass. Grain-size analysis of all collected samples was used to reconstruct the total grain-size distribution which displays a peak at 0.5 F. Column height was estimated at 3.3–7 km by combining barometrical altimeter data during over-flights with the analysis of images and videos. This was used to estimate a total erupted mass of 4.4 ± 0.6 1010 kg. Simulations showed that the deposit was significantly affected by variations in wind direction and mass eruption rate, with deposits being dispersed mainly on the E sector of the volcano due to a dominant easterly wind. Our study underlines that basaltic volcanoes, such as Etna, can produce huge amounts of ash, as well as lava, and that an improvement in the knowledge of dispersal processes during prolonged explosive activity is required to better mitigate the associated hazards.218 32
