Abstract:

Seismology is a key tool in the forecasting of volcanic eruptions. The onset of an eruption is often preceded and accompanied by an increase in local seismic activity, driven by fracturing within the edifice. For closed systems, with a repose interval of the order of a century or more, this fracturing must occur in order to create a pathway for the magma to reach the surface. Time-to-failure forecasting models have been shown to be consistent with seismic acceleration patterns prior to eruptions at volcanoes in subduction zone settings. The aim of this research is to investigate the patterns i

Abstract:

This thesis describes the investigation of fluid dynamic processes involved in maintained explosive volcanic eruptions. The thesis is divided into chapters relating to dynamical processes in a volcanic system: evolution and evacuation of a reservoir of molten rock, flow in a narrow conduit to the Earth's surface, and subsequent transport in the atmosphere. In chapter 2, we calculate the mass erupted, prior to caldera collapse, from a chamber as the pressure changes from a certain overpressure to a specified underpressure at which wall collapse occurs. The compressibility of the magma increases

Abstract:

Phreatomagmatic eruptions result from the explosive interaction between magma and some external source of water, and produce deposits which are usually distinctive in nature from those of magmatic eruptions. The widespread deposits of large-scale phreatomagmatic eruptions (usually termed Phreatoplinian) are poorly studied relative to their magmatic counterparts and, consequently, current models for large-scale phreatomagmatic volcanism remain speculative. The Hatepe ash and Rotongaio ash (units 3 and 4 of the 1.85 ka Taupo eruption) are two classical widespread phreatomagmatic fall deposits. T

Abstract:

The term “blue-sky eruption” (BSE) can be used to describe eruptions which are unexpected or have no detected precursory activity. Case study analyses indicate that they have a diverse range of characteristics and magnitudes, providing both direct and indirect hazards and occur in both under-developed and developed countries. BSEs can be a result of physical triggers (e.g. the lack of physically detectable precursors or a lack of understanding of the eruption model of the volcano), social triggers (such as an inadequate monitoring network), or a combination of the two.

Abstract:

Volatile elements play an important role in almost every aspect of sub-volcanic systems, from the generation and storage of magma, to the timing and style of volcanic activity. Currently, the most common method for assessing pre-eruptive magmatic volatile contents is through analysis of trapped melt inclusions. However, the reliability of this record is uncertain, necessitating development of new, independent petrologic methods for determining the pre-eruptive volatile contents of past eruptions. This thesis combines physical and chemical models with empirical analyses to develop the use of ap

Increasing rates of volcano-tectonic (VT) seismicity are one of the most common precursors before volcanic eruptions. Previous quantitative studies of VT precursors have focussed on volcanoes in subduction zones, with compressional background stress fields. To compare these studies with similar precursors observed before eruptions in extensional stress fields, VT seismicity was examined before ten flank eruptions at Mt Etna, in Sicily, between 1977 and 2008. Thirty percent of the eruptions were preceded by exponential increases in VT seismicity, with durations of months to years. Two exponenti

Abstract:

Large explosive volcanic eruptions inject SO2 into the stratosphere where it is oxidised to sulphate aerosols which reflect sunlight. This causes a reduction in global temperature and precipitation lasting a few years. Here the robust features of this precipitation response are investigated, using superposed epoch analysis that combines results from multiple eruptions. The precipitation response is first analysed using the climate model HadCM3 compared to two gauge based land precipitation datasets. The analysis is then extended to a large suite of state-of-the art climate models participating

Abstract:

'Natural' disasters have traditionally been viewed as the result of an extreme physical environment. A radical backlash against this dominant view, in the nineteen seventies and eighties, moved the debate to the opposite extreme and in doing so replaced physical with social determinism. Vulnerability analysis is proposed as a methodology that bridges these extremes. It takes into account individual decision making, social milieu and physical hazard when describing human habitation in areas of volcanic activity. It is argued that vulnerability should be defined in terms of universal human needs

Eruption dynamics are sensitive to ash aggregation, and ash aggregates (e.g. accretionary lapilli) are commonly found in eruptive deposits, yet few experiments have been conducted on aggregation phenomena using natural materials. Experiments were developed to produce a probabilistic relationship for the efficiency of ash aggregation with respect to particle size, collision kinetic energy and atmospheric water vapor. The laboratory experiments were carried out in an enclosed tank designed to allow for the control of atmospheric water vapor. A synthetic ash proxy, ballotini, and ash from the 20

The inner crater stratigraphy, exposed on the southern wall, is divided into seven lithostratigraphic units (A to G), while the northern stratigraphy is obscured by the inward collapse of the crater rim.

Abstract:

The evolution of rhyolitic lava from effusion to cessation of activity is poorly understood. Recent lava dome eruptions at Unzen, Colima, Chaiten and Soufrière Hills have vastly increased our knowledge on the changes in behaviour of active domes. However, in ancient domes, little knowledge of the evolution of individual extrusion events exists. Instead, internal structures and facies variations can be used to assess the mechanisms of eruption. Rhyolitic magma rising in a conduit vesiculates and undergoes shear, such that lava erupting at the surface will be a mix of glass and sheared vesic

First, I created a new numeric metric for statistically analyzing reproductive strategies in mammals and tested the impact of diet and body size on reproductive

Explosive magma-water interaction (MWI) during hydromagmatic eruptions generates substantially more fine-grained volcanic ash than equivalent 'dry' eruptions.

By developing new ways to characterise and interpret volcanic ash properties, this thesis shows that (a) magmatic vesiculation prior to MWI is the rule rather than the exception, (b) rapid
