Available in PDF, EPUB and Kindle. Book excerpt: This thesis focuses on using spectroscopic gas emissions data to understand degassing processes occurring during low-intensity explosive activity at Santiaguito lava dome, Guatemala. It results in a refinement of the ultra violet camera spectroscopic technique; the proposal of a trigger mechanism for low-intensity explosions during lava dome growth; and the first successful modelling of an unsteady explosion plume. The ultra violet camera provides high spatial and temporal resolution spectroscopic measurements of volcanic 802, However, data collection is difficult under the non-ideal conditions typically encountered at silicic volcanoes. A new processing protocol is developed that corrects for plume-instrument distance and in-plume ash/aerosols, permitting data collection at 8antiaguito. The resulting dataset is used to constrain the trigger mechanism of 8antiaguito explosions. The lava dome is found to be continuously permeable, whilst explosions contain as little as 150 kg 802 - characteristics incompatible with gas pressurisation beneath an impermeable plug. Rather, the data support a model in which transient explosive degassing pathways are generated at the conduit margins through shear-driven fracturing. Rheological modelling shows that this process is likely to occur during even extremely slow extrusion of high-crystallinity intermediate magma, on account of the very high viscosity of such magma. This model is further supported by the discovery of tuffisite veins in Santiaguito dacite. Santiaguito explosions form short-duration plumes that may be used as observable proxies for larger Vulcanian plumes. Ultra violet camera data have been used to define time-varying boundary conditions for a cutting-edge unsteady plume model. This represents a first attempt to compare field observations of a volcanic plume with model predictions using field-derived boundary conditions. The resulting simulation closely recreates the observed plume ascent, in contrast to approximations made using steady and instantaneous plume models. This explicitly shows that unsteady effects are critical to understanding Vulcanian plume dynamics.

This book was released on 2017 with total page 175 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cerro Quemado and Volcan de Almolonga are two Quaternary volcanoes located in southwestern Guatemala, approximately 5 km from the large city of Quetzaltenango. Both volcanoes neighbor Santa Maria which produced an explosive and catastrophic eruption in 1902 and subsequently created the Santiaguito dome. Cerro Quemado's most recent eruption in 1818 produced a dacite lava flow that contains abundant mafic inclusions. An undated Volcan de Almolonga eruption produced an andesitic lava. Pre-eruptive intensive variables using various geothermometers and geohygrometers were calculated to determine magmatic temperatures and water contents for each lava flow. Two liquids were involved in the 1818 lava flow. The first is a rhyolite liquid with a temperature of 793--915°C and a water content of 4.3--5.1 wt.%, and the second is a mafic liquid with a temperature of 1009--1057°C. Plagioclase equilibrium from a Volcan de Almolonga lava flow also suggests two liquids existed prior to eruption, a rhyolite liquid with a temperature of 872--918°C and a water content of 4.3--5.0 wt.%, and an andesite liquid with a temperature of 941--1015°C and a water content of 2.9--5.1 wt.%. Models of magmatic evolution are proposed for each lava flow. The 1818 Cerro Quemado flow is thought to have erupted because of an influx of mafic magma that injected into a static rhyolite magma. At Volcan de Almolonga, two eruptive models are proposed. The first model is a single reservoir model, where the andesite magma exists within a crystal mush zone that is overlaid by a rhyolite magma. An unidentified mechanism triggered the eruption of both magmas to create the lava flow seen at the surface. The second model is a two reservoir model, where each liquid exists as a magma in its own reservoir. An unidentified mechanism triggers the eruption that incorporates magma from the oval reservoir.
