    Abstract
    Abstract

    The indicator is defined as the number of volcanic eruptions that produced significant impacts on human activities during the year.
    In 2024, both Etna and Stromboli were active, with the most pronounced peaks occurring between July and August.

    Description

    The indicator is determined by the number of volcanic eruptions that have occurred in Italian territory and have had notable effects or consequences on the environment and human activities.

    Purpose

    To describe volcanic activity, its environmental effects, and its impact on human activities in Italian territory.

    Processing methodology

    The indicator was developed through in-depth bibliographic research of the necessary data. This research was conducted mainly online, using sources from the Istituto Nazionale di Geofisica e Vulcanologia (INGV - https://www.ingv.it) and the Civil Protection website (https://www.protezionecivile.gov.it).

    Year
    Data quality

    Data related to volcanic eruptions are derived from standardized procedures and are therefore reliable. The indicator is well-founded in technical and scientific terms and is comparable over time and space.

    State assessment/description

    In 2024, volcanic activity on Etna included eruptions that reached notable peaks between July and August.
    Routine activity at Stromboli also intensified during the same period, showing higher-than-usual eruptive peaks.

    Trend assessment/description

    A clear trend cannot be determined. It is worth noting that the years in which volcanic activity caused the greatest damage were 2002—when numerous injuries occurred due both to the eruption itself and to the anomalous wave generated by Stromboli—and 2019, when one person was killed and another injured during an eruption of Stromboli (Table 3).
    In 2003, 2006, 2009, 2012, and 2016, no eruptions occurred that significantly interfered with human activities, nor were any damages to people or property reported.
    Overall, volcanic activity has remained steady, punctuated by occasional intensity peaks.

    Comments

    ETNA

    Strombolian activity at the Voragine crater intensified progressively starting on 24 July, culminating on 4 August in a lava-fountain episode that produced an eruptive plume rising to about 10 km above sea level and dispersing toward the east and southeast.
    The fallout of pyroclastic material (lapilli and ash) over Etna’s eastern flank affected numerous settlements, including Fleri, Fornazzo, Zafferana, Milo, Santa Venerina, Giarre, Riposto, Stazzo, Torre Archirafi, San Giovanni La Punta, Viagrande, Aci Sant’Antonio, Aci Catena, Aci Castello, Aci Trezza, and Acireale. INGV-OE staff measured pyroclastic deposits ranging from 3.8 to 4.2 kg/m² between Milo, Santa Venerina, and Zafferana, and recorded lapilli with a maximum axis of about 4 cm in Milo.
    Catania Fontanarossa Airport was partially closed.

    STROMBOLI

    The eruption began on 4 July with the opening of a new effusive vent at around 700 meters above sea level, producing a lava flow down the Sciara del Fuoco. This flow in turn generated pyroclastic currents that reached the coastline and propagated into the sea (Figures 1 and 2).
    As activity intensified—especially on 4 July—Civil Protection authorities raised the alert level from orange to red, triggering the pre-alert operational phase. This ensured effective management of public safety but had significant economic and logistical consequences for the island, linked in particular to tourism.
