DATA MINING TECHNIQUES ON VOLCANO MONITORING
… where data mining techniques are applied for volcano data analysis and surveillance purpose. In particular, an application for clustering infrasound signals and another to index an thermal image database are presented.

Towards Improved Volcano Monitoring via Automatic Classification of Continuous Tremor
… means to detect previously unknown patterns in volcano-seismic signals. Some of these patterns may be precursors to eruption, or change of volcanic activity state. This is particularly interesting for ‘wet’ volcanic systems such as Whakaari (White Island), which regularly produce …

Experimental and Computational Approaches to Enhance the Gravimetric Monitoring of Volcanic Areas
… because it is the most intensively monitored volcano in the world but also because there was the possibility to perform directly in the field gravity measurements, both discrete and continuous, with the instruments owned by the Istituto Nazionale di Geofisica e Vulcanologia (INGV) - Sezione di …

INSIGHTS INTO ERUPTION DYNAMICS AND SHALLOW PLUMBING SYSTEM OF MT. ETNA BY INFRASOUND AND SEISMIC SIGNALS
… processes and the plumbing system of the volcano. Indeed, the eruptive styles are controlled by the interplay between magma dynamics and the plumbing system. In multi-vent volcanoes, such as Mt. Etna, where volcanic activity can rapidly vary over time and be simultaneously at the different …

Evolutionary data assimilation at Long Valley Caldera, CA
… modeling, the time-dependent evolution of volcanoes is still poorly understood. Of particular need are methods for combining extensive monitoring data sets with dynamic models. Sequential data assimilation has been shown to be powerful approach for linking models and data to improve the use …

Monitoring Erebus volcano's active lava lake; tools, techniques and observations
… Antarctica, the 3794-m-high crater of Erebus volcano has hosted a phonolite lava lake for decades. Previous studies have shown that many of the lake’s characteristics, such as surface velocity, gas flux and gas composition, exhibit a pronounced pulsatory behaviour on a time-scale of ∼10 min. …

Exploiting Artificial Intelligence in Volcanic Monitoring for Distributed Acoustic Sensing Analysis and GNSS-Based Source Inversion [L’Intelligenza Artificiale per il monitoraggio vulcanico: analisi di segnali DAS e modellazione della sorgente tramite inversione di dati GNSS]
Il rischio tangibile connesso alla pericolosità vulcanica ha suscitato un notevole interesse scientifico e sociale per il monitoraggio dei vulcani attivi. Negli ultimi anni, l'Intelligenza Artificiale (AI), in particolare il Machine Learning (ML), è emersa come uno strumento promettente per …

Towards monitoring volcanoes in Iceland and Hawai’i with seismic velocity variations
… is an exciting technique for studying volcanoes because it provides a continuous measurement of relative seismic velocity (dv/v), which is sensitive to magmatic processes that affect the physical properties of the surrounding crust. However, understanding the causal mechanisms …
