Open AccessAssessing flank instability of Stromboli volcano (Italy) by reappraising the 30 December 2002 tsunamigenic landslides
Bearing in mind the destructive potential of tsunamis induced by volcanic landslides, the tsunamigenic event occurring at Stromboli volcano in Italy on 30 December 2002 has been re-examined here, by means of v...

Open AccessContinuous radon monitoring during seven years of volcanic unrest at Campi Flegrei caldera (Italy)
This is a seven-year study (1/7/2011-31/12/2017) of radon monitoring at two sites of Campi Flegrei caldera (Neaples, Southern Italy) that in the last 70 years experienced repeated phases of volcanic unrest. Th...

Insight into Vent Opening Probability in Volcanic Calderas in the Light of a Sill Intrusion Model
The aim of this paper is to discuss a novel approach to provide insights on the probability of vent opening in calderas, using a dynamic model of sill intrusion. The evolution of the stress field is the main f...

Tephra fallout hazard assessment at the Campi Flegrei caldera (Italy)
Tephra fallout associated with renewal of volcanism at the Campi Flegrei caldera is a serious threat to the Neapolitan area. In order to assess the hazards related with tephra loading, we have considered three...

Pyroclastic flow hazard assessment at Vesuvius (Italy) by using numerical modeling. I. Large-scale dynamics
The thermofluid dynamics of pyroclastic flows down the slopes of Vesuvius (Italy) were investigated using physical modeling of the magma ascent and pyroclastic dispersal processes. The expected properties and ...

Pyroclastic flow hazard assessment at Vesuvius (Italy) by using numerical modeling. II. Analysis of flow variables
The numerical simulations of pyroclastic flow propagation along the Vesuvius slopes, described in a companion paper (Todesco et al. 2002, this volume), are herein analyzed in terms of the local variables of th...

Transient dynamics of vulcanian explosions and column collapse
Several analytical and numerical eruption models have provided insight into volcanic eruption behaviour1,2,3,4,5, but most address plinian-type eruptions where vent conditions are quasi-steady. Only a few studies...
