[1] Between 2007 and early 2008, the Istituto Nazionale di Geofisica e Vulcanologia (INGV) monitoring networks on Etna volcano recorded a recharging phase that climaxed with new effusive eruption 13 May 2008 lasted about 14 months. A dike-forming intrusion was accompanied by violent seismic swarm, more than 230 events in first 6 h, largest being ML = 3.9. In meanwhile, marked ground deformation permanent tilt GPS networks, sudden changes summit area were detected five continuously recording...
The 8th International Comparison of Absolute Gravimeters (ICAG2009) took place at the headquarters Bureau Weights and Measures (BIPM) from September to October 2009. It was first ICAG organized as a key comparison in framework CIPM Mutual Recognition Arrangement Committee for (CIPM MRA) 1999). ICAG2009 composed Key (KC) defined by MRA, Consultative Mass Related Quantities (CCM) designated CCM.G-K1. Participating gravimeters their operators came national metrology institutes (NMIs) or (DIs)...
Improving lava flow hazard assessment is one of the most important and challenging fields volcanology has an immediate practical impact on society. Here, we present a methodology for quantitative hazards based combination field data, numerical simulations probability analyses. With extensive data available historic eruptions Mt. Etna, going back over 2000 years, it been possible to construct two maps, flank other summit eruptions, allowing analysis likely future courses flows. The effective...
We present a new method that uses cooling curves, apparent in high temporal resolution thermal data acquired by geostationary sensors, to estimate erupted volumes and mean output rates during short lava fountaining events. The 15 minute of the allows phases waxing peak activity be identified (150‐to‐810 minute‐long) Cooling which decay over 8‐to‐21 hour‐periods following event, can also identified. Application 19 events recorded at Etna MSG's SEVIRI sensor between 10 January 2011 9 2012,...
We are grateful to EUMETSAT for SEVIRI data, NASA MODIS data, and toNOAAfor AVHRR data. The authors thank one anonymous reviewer V. Acocella their helpful constructive comments. This study was performed with the financial support from V3‐LAVA project (INGV‐DPC 2007‐2009 contract).
Abstract. One of the most important tasks modern volcanology is construction hazard maps simulating different eruptive scenarios that can be used in risk-based decision making land-use planning and emergency management. The first step quantitative assessment volcanic hazards development susceptibility (i.e., spatial probability a future vent opening given past activity volcano). This challenging issue generally tackled using probabilistic methods use calculation kernel function at each data...
Abstract Satellite remote sensing techniques and lava flow forecasting models have been combined to enable a rapid response during effusive crises at poorly monitored volcanoes. Here we used the HOTSAT satellite thermal monitoring system MAGFLOW emplacement model forecast hazards 2014–2015 Fogo eruption. In many ways this was one of major eruption recent years, since flows actually invaded populated areas. Combining data modeling allowed mapping probable evolution fields while ongoing...
Twenty-one years of ASTER global thermal infrared (TIR) acquisitions provide a large amount data for volcano monitoring. These data, with high spatial and spectral resolution, enable routine investigations volcanoes in remote inaccessible regions, including those no ground-based However, the dataset is too to be manually analyzed on basis. Here, we systematically process over several using deep learning algorithm automatically extract volcanic anomalies. We explore application Convolutional...
Spaceborne remote sensing of high-temperature volcanic features offers an excellent opportunity to monitor the onset and development new eruptive activity. To provide a basis for real-time response during events, we designed developed volcano monitoring system that call HOTSAT. This multiplatform can elaborate both Moderate Resolution Imaging Spectroradiometer (MODIS) Spinning Enhanced Visible Infrared Imager (SEVIRI) data, it is here applied Etna volcano. The main advantage this approach...
Abstract The statistical analysis of volcanic activity at Mt Etna was conducted with the twofold aim (1) constructing a probability map for vent opening future flank eruptions and (2) forecasting expected number eruptive events summit craters. spatiotemporal new volcano is based on spatial locations frequency starting from 1610. Thanks to completeness accuracy historical data over last four centuries, we examined in detail temporal distribution showing that effusive follow nonhomogenous...
Estimates of lava volumes provide important data on the flooding history and evolution a volcano. For mapping these volcanic deposits, advancement satellite remote sensing techniques offer great potential. Here we characterize eruptive events occurred at Mt Etna between January 2011 December 2015 leading to emplacement numerous flows formation new pyroclastic cone (NSEC) eastern flank South East Crater. The HOTSAT system is used analyze acquired by SEVIRI sensor in order detect thermal...
Mature volcanoes usually erupt from a persistent summit crater. Permanent shifts in vent location are expected to occur after significant structural variations and seldom documented. Here we provide such an example that recently occurred at Etna. Eruptive activity Mount Etna during 2007 focused the Southeast Crater (SEC), youngest (formed 1971) most active of four craters, consisted six paroxysmal episodes. The related erupted volumes, determined by field-based measurements radiant heat flux...
The Etna flank eruption that started on 24 December 2018 lasted a few days and involved the opening of an eruptive fissure, accompanied by seismic swarm shallow earthquakes, significant SO2 flux release, large widespread ground deformation, especially eastern volcano. Lava fountains ash plumes from uppermost fissure stage, causing disruption to Catania International Airport, were followed quiet lava effusion within barren Valle del Bove depression until 27 December. This was first occur at...
Explosive volcanic eruptions inject a variety of particles and gases into the atmosphere, forming clouds that significantly impact human health, climate, aviation safety. Accurately capturing temporal evolution these is essential for understanding their dynamics improving predictive capabilities. Due to rapid unpredictable nature explosive eruptions, can form, expand, disperse in short timeframes. For this reason, high-temporal-resolution geostationary satellite data are indispensable...
Lava flows are complex, non-Newtonian fluids with visco-thermal dependencies that can overcome barriers, form tunnels, and significantly impact surrounding areas. Understanding predicting these critical for quantifying volcanic hazards. Computational Fluid Dynamics (CFD) models indispensable tools simulating lava dynamics, but they often entail high computational costs, limiting their real-time applicability. To address challenges, we propose an AI-enhanced CFD emulator flows, designed to...
Identifying changes in a volcano's unrest and tracking the evolution of its eruptive activity are crucial for effective volcanic surveillance monitoring. Variations gas composition amount can be associated with pre-eruptive volcano plumbing system. When combined petrological studies, emitted Sulphur dioxide (SO2) reflects magma involved (erupted or degassed), making it useful parameter constraining processes, dynamics, volume magma. This work proposes an Artificial Intelligence (AI) strategy...
