Geotourism in volcanic areas attracts millions of visitors each year travelling to see and explore volcanic areas. One of the world’s most famous and visited volcanic areas is Somma-Vesuvius. Here, tourism is mainly concentrated around the central crater while the rest of the volcano, part of Vesuvius National Park, is largely unvisited. The volcano’s worldwide fame is primarily linked to its explosive activity, most notably t...

On 19 September 2021, the Cumbre Vieja volcano in the southern part of La Palma (Canary Islands) erupted after 50 years of quiescence. A northwest-southeast eruptive fissure opened on the west flank of the volcano, producing explosive and effusive activity that lasted until 13 December 2021. The explosive activity from the fissure built up a new cone named Tajogaite, and the discharge of high temperature and low viscosity magm...

The gravitational instability of hot material deposited during eruptive activity can lead to the formation of glowing avalanches, commonly known as deposit-derived pyroclastic density currents (PDCs). These currents can travel hundreds of metres to several kilometres from the source at exceptionally high temperatures, posing a catastrophic hazard to areas surrounding steep-slope volcanoes. The occurrence of deposit-derived PDC...

When a lava flow enters a body of water, either a lake, sea, river or ocean, explosive interaction may arise. However, when it is an 'a'ā lava flow entering water, a more complex interaction occurs, that is very poorly described and documented in literature. In this paper, we analysed the 2–4 ka San Bartolo lava flow field emplaced on the north flank of Stromboli volcano, Italy. The lava flow field extends from ~ 650 m a.s.l....
