Dynamics of ash eruptions at Vesuvius
… analysis of the stratigraphic successions at Vesuvius revealed that such type of eruptions have occurred repeatedly in the last 4000 years of activity. This type of activity has been overlooked in the past and the mechanism of ash production in these eruptions is not yet clear. The detailed …

Elastic Propagation in random media: applications to the imaging of volcano structures
… to two volcanic areas: Campi Flegrei and Mt. Vesuvius. Volcanic and seismological active areas are often characterized by complex velocity structures, due to the presence of rocks with different elastic properties. I introduce some modifications to the original method in order to make it …

The Smallest Base and Precious Metal Deposits in the World: Vapor Transport and deposition of Co-Cu-Sn-Ag alloys in vesicles
… the mafic volcanoes of Kilauea in Hawaii and Vesuvius, Stromboli and Etna in Italy. It is inferred that the metals for these alloys were transported (in part) as chloride complexes, and that the metal ratios in the alloys may be a function of S/Cl. Alloy compositions in each system are …

Development of rate-dependent thermoplastic constitutive models for numerical analysis of ceramics at high-temperature
… is the outcome of the secondment period at the Vesuvius Group, within the framework of the IAPP European project HOTBRICKS (contract number PIAPP GA-2013-609758).

“The most popular humorist who ever lived” : Mark Twain and the transformation of American culture
… comedians, such as Artemus Ward and Petroleum Vesuvius Nasby; and clowns and minstrels, who were placed at the bottom of the hierarchy. I argue that Mark Twain muddied the hierarchical distinctions between class-appropriate leisure and burgeoning forms of mass entertainment, between uplifting …

Subaltern Spaces in the Ancient City: Cultural Identity, Spatial Memory, and Networks of Meaning in Roman Pompeii
… destroyed and preserved by the eruption of Vesuvius in 79 CE; one that has been widely studied for its preservation of a Roman urban environment that was ‘frozen in time’. The excellent preservation of the site reveals a colonial material record that has long encouraged terminal narratives …

Stratigraphic and Geochemical Insights into Explosive Volcanism in Northwestern Nicaragua: Case Studies from the Momotombo-Monte Galán Volcanic System and Cosigüina Volcano
… volcanoes since the fateful eruption of Vesuvius in 79 A.D. famously destroyed Pompeii, but there is still a great deal left to learn in order to properly forecast the timing and impact of explosive eruptions. This dissertation focuses on expanding our understanding of the eruptive …

Experimental Determinations and Modelling of the Viscosity of Multicomponent Natural Silicate Melts: Volcanological Implications
… style of phonolitic volcanoes (e.g. Vesuvius) and the dominantly effusive style of basalts. Variations in composition between the trachytes translate into differences in liquid viscosity of nearly two orders of magnitude in dry conditions, and less than one order of magnitude in …
