Full-text available
An innovative method of estimating the relative risk of buildings exposed to seismic and tsunami hazards in volcanic islands is applied to Stromboli (Italy), a well-known stratovolcano affected by moderate earthquakes and mass-flow-induced tsunamis. The method uses a pre-existing quali-quantitative analysis to assess the relative risk indices of bu...
Conference Paper
Full-text available
Pyroclastic density currents (PDCs) at Stromboli are typically associated with Strombolian paroxysms. The main mechanisms originating the currents include the eruptive column collapse (i.e. primary PDC), and the remobilization and avalanching of fresh pyroclastic deposits (i.e. secondary PDC). Whereas primary PDCs are commonly confined into the Sci...

Full-text available
Two paroxysmal explosions occurred at Stromboli on July 3 and August 28, 2019, the first of which caused the death of a young tourist. After the first paroxysm an effusive activity began from the summit vents and affected the NW flank of the island for the entire period between the two paroxysms. We carried out an unsupervised analysis of seismic a...

Muography represents a recent and innovative tool for investigating the interior of active volcanoes. However, when dealing with frequently erupting open‐vent volcanoes such as Stromboli, any result should take into consideration the structural and morphology changes caused by the eruptive activity. This may cause either summit collapses by magma w...

One of the most efficient and cost-effective tools for landslide risk mitigation is often the setup of an early warning system (EWS). Even if the latter encompass both technical-scientific and social-economic topics, the focus of this note is on the monitoring and forecasting components of a slope-scale landslide EWS. In this framework, a landslide...
Chapter
Volcano landslides or explosions-induced mass flows constitute an important trigger of tsunamis. Even if landslide-induced tsunamis can produce more local impacts comparable earthquake-induced tsunamis, large volume failure of volcanic edifice may cause tsunamis with widespread effects. Considering this, successful strategies for volcano slope inst...
