“…Each of these Vulcanian cycles is characterized by total fallout masses of 0.1-1×10 7 kg over durations of 3 weeks to 3 years. The most recent eruption of La Fossa in 1888-1890, described in detail by Mercalli and Silvestri (1891) and De Fiore (1922), was characterized by explosions occurring every 4 hours to 3 days and associated with plume heights of 1-10 km asl (Di Traglia 2011;Di Traglia et al 2013;Mercalli and Silvestri 1891). A detailed description of the probabilistic modelling of these eruption scenarios can be found in Biass et al (2016).…”

“…Second, La Fossa volcano was used to illustrate short-lasting sub-Plinian/Plinian eruptions and long-lasting Vulcanian cycles. The subPlinian eruptions were simulated using a One Eruption Scenario, whereas Vulcanian cylces were simulated using (1891), Bianchi (2007) and Di Traglia et al (2013). ESPs for Cordón Caulle are inferred from Bonadonna et al and Pistolesi et al (2015) based on the 2011 eruption.…”

“…Table 2 summarizes ESPs for both scenarios based on Mercalli and Silvestri (1891); Bianchi (2007) and Di Traglia et al (2013). Four variables need to be considered when displaying the probability of exceeding a given tephra accumulation, including geographic coordinates (Easting, Northing or longitude, latitude), a threshold of tephra accumulation and its associated exceedance probability.…”

TephraProb is a toolbox of Matlab functions designed to produce scenario-based probabilistic hazard assessments for ground tephra accumulation based on the Tephra2 model. The toolbox includes a series of graphical user interfaces that collect, analyze and pre-process input data, create distributions of eruption source parameters based on a wide range of probabilistic eruption scenarios, run Tephra2 using the generated input scenarios and provide results as exceedence probability maps, probabilistic isomass maps and hazard curves. We illustrate the functionality of TephraProb using the 2011 eruption of Cordón Caulle volcano (Chile) and selected eruptions of La Fossa volcano (Vulcano Island, Italy). The range of eruption styles captured by these two events highlights the potential of TephraProb as an operative tool when rapid hazard assessments are required during volcanic crises.

The intense explosive and effusive volcanic activity of the last 1000 years at La Fossa volcano (Vulcano Island, Italy) was characterized by the eruption of magmas ranging in composition from latites to trachytes and rhyolites, as well as K-rich trachytes. Evidence of syn-eruptive mixing among these magmas is frequently observed in the form of magmatic enclaves and bands in lava flows and pyroclastic products. The petrological and volcanological diversity of the erupted materials suggests that complex differentiation processes occurred in the shallow part of the plumbing system. With the aim to reconstruct the magmatic feeding system and to identify the differentiation processes behind such a petrologic complexity, we analysed lavas and pyroclastic products representative of the recent eruptive sequences at La Fossa and combined the petrochemical features with thermo-barometric calculations, geochemical modelling and temperature gradient experiments. Thermo-barometric calculations indicate that the K-rich trachytic magma crystallized at lower pressure (160 ± 54 MPa) compared to the latitic (307 ± 47 MPa) and trachytic (208 ± 30 MPa) magmas. Differentiation modelling suggests that both trachytic and rhyolitic compositions can be obtained through differentiation of a common latitic magma, essentially by varying the plagioclase/ sanidine ratio. Temperature gradient experiments, performed at the conditions inferred for the shallow plumbing system of La Fossa volcano (150 MPa and 1050-900 °C), indicate different paths of melt differentiation that overall produce an increase of the SiO 2 /K 2 O ratio with the increasing H 2 O in the system (from 0 to 4 wt.%). This is consistent with the origin of K-rich trachytes at lower pressure and lower H 2 O content. In turn, the formation of crystal-poor rhyolites is explained by the segregation of the interstitial melt formed in a latitic-trachytic crystal mush, favoured by the second boiling of the melt and consequent exsolution of a fluid phase.
