This study presents a Probabilistic Tsunami Hazard Assessment for Stromboli, Italy, quantifying long-term risks from landslide-generated tsunamis. By combining new simulation databases with expert-derived probabilities, it introduces a method to model hazard uncertainty. Results show significant risk to coastal areas over 50 years, with high probabilities of inundation exceeding 0.5 m and notable chances of severe impacts at key locations.

This study examines tsunami hazards linked to volcanic activity at Stromboli volcano, Italy and is aimed at developing a first Probabilistic Tsunami Hazard Assessment. In particular, in this study a review identified 16 tsunamis (1879–2024), mostly linked to paroxysmal eruptions. Expert elicitation suggests tsunamigenic landslides may recur every 10–12 years, with high likelihood along the Sciara del Fuoco, especially at mid-elevations and moderate volumes, informing future hazard assessment.

Short summary
To better understand volcanic tsunamis, we simulated thousands of granular flows at Stromboli volcano. For flows starting above water, volume dictates the wave size. For underwater flows, volume and starting depth are equally important. These findings establish simple scaling rules to quickly predict tsunami sizes based on flow characteristics, vastly improving hazard assessments and emergency planning for coastal communities threatened by volcanic avalanches.

Water vapor makes up more than 70 % of volcanic gas emissions but accurate H2O flux measurements remain challenging. We developed a multi-band near-infrared camera system that directly measures volcanic water vapor. Testing and validating our approach at two different volcanic settings in Chile and Iceland we found underestimation of water vapor fluxes and provides data that improves our understanding of volcanic activity and gas release patterns.

We studied air pollution caused by volcanic emissions, a poorly understood hazard in populated areas. We present a large dataset of high-quality measurements of sulfur dioxide gas and fine aerosol particulate matter collected during ongoing series of eruptions in Iceland. We revealed rapid, localized changes in pollutant concentrations at ground level, with implications for assessing population exposure during volcanic eruptions.

We study the lahar hazard due to the remobilization of tephra deposits from reference eruptions at Somma–Vesuvius. To this end, we rely on the results of two companion papers dealing with field data and model calibration and run hundreds of simulations from the catchments around the target area to capture the uncertainty in the initial parameters. We process the simulations to draw maps of the probability of overcoming thresholds in lahar flow thickness and dynamic pressure relevant for risk.

We present a numerical model for lahars generated by the mobilization of tephra deposits from a reference size eruption at Somma–Vesuvius. The paper presents the model (pyhsics and numerics) and a sensitivity analysis of the processes modelled, numerical schemes, and grid resolution. This work provides the basis for application to hazard quantification for lahars in the Vesuvius area. To this end, we rely on results of the two companion papers (Part 1 on field data, Part 3 on hazard maps).

We study the distribution of two historical pyroclastic fall–flow and lahar deposits from the sub-Plinian Vesuvius eruptions of 472 CE Pollena and 1631. The motivation comes directly from the widely distributed impact that both the eruptions and lahar phenomena had on the Campanian territory, not only around the volcano but also down the nearby Apennine valleys. Data on about 500 stratigraphic sections and modeling allowed us to evaluate the physical and dynamical impact of these phenomena.

We present version 2 of the numerical code IMEX-SfloW2D. With this version it is possible to simulate a wide range of volcanic mass flows (pyroclastic avalanches, lahars, pyroclastic surges), and here we present its application to transient dilute pyroclastic density currents (PDCs). A simulation of the 1883 Krakatau eruption demonstrates the capability of the numerical model to face a complex natural case involving the propagation of PDCs over the sea surface and across topographic obstacles.

This work addresses a quantitative hazard assessment on the possible impact on air traffic of a future ash-forming eruption on the island of Jan Mayen. Through high-performance computing resources, we numerically simulate the transport of ash clouds and ash concentration at different flight levels over an area covering Iceland and the UK using the FALL3D model. This approach allows us to derive a set of probability maps explaining the extent and persisting concentration conditions of ash clouds.

The purpose of the EUNADICS-AV (European Natural Airborne Disaster Information and Coordination System for Aviation) prototype early warning system (EWS) is to develop the combined use of harmonised data products from satellite, ground-based and in situ instruments to produce alerts of airborne hazards (volcanic, dust, smoke and radionuclide clouds), satisfying the requirement of aviation air traffic management (ATM) stakeholders (https://cordis.europa.eu/project/id/723986).

Short summary
The lava eruption at Fagradalsfjall in 2021 was the most visited eruption in Iceland, with thousands of visitors per day for 6 months. To address the short- and long-term danger of lava inundating infrastructure and hiking paths, we used the lava flow model MrLavaLoba before and during the eruption. These simulations helped communicate lava hazards to stakeholders and can be used as a case study for lava hazard assessment for future eruptions in the area, which are likely to be more destructive.
The lava eruption at Fagradalsfjall in 2021 was the most visited eruption in Iceland, with...
