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.

Download or read book Volcanic Eruptions and Their Repose Unrest Precursors and Timing written by National Academies of Sciences, Engineering, and Medicine and published by National Academies Press. This book was released on 2017-07-24 with total page 135 pages. Available in PDF, EPUB and Kindle. Book excerpt: Volcanic eruptions are common, with more than 50 volcanic eruptions in the United States alone in the past 31 years. These eruptions can have devastating economic and social consequences, even at great distances from the volcano. Fortunately many eruptions are preceded by unrest that can be detected using ground, airborne, and spaceborne instruments. Data from these instruments, combined with basic understanding of how volcanoes work, form the basis for forecasting eruptionsâ€"where, when, how big, how long, and the consequences. Accurate forecasts of the likelihood and magnitude of an eruption in a specified timeframe are rooted in a scientific understanding of the processes that govern the storage, ascent, and eruption of magma. Yet our understanding of volcanic systems is incomplete and biased by the limited number of volcanoes and eruption styles observed with advanced instrumentation. Volcanic Eruptions and Their Repose, Unrest, Precursors, and Timing identifies key science questions, research and observation priorities, and approaches for building a volcano science community capable of tackling them. This report presents goals for making major advances in volcano science.

Download or read book Statistics in Volcanology written by Heidy M. Mader and published by Geological Society of London. This book was released on 2006 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: Statistics in Volcanology is a comprehensive guide to modern statistical methods applied in volcanology written by today's leading authorities. The volume aims to show how the statistical analysis of complex volcanological data sets, including time series, and numerical models of volcanic processes can improve our ability to forecast volcanic eruptions. Specific topics include the use of expert elicitation and Bayesian methods in eruption forecasting, statistical models of temporal and spatial patterns of volcanic activity, analysis of time series in volcano seismology, probabilistic hazard assessment, and assessment of numerical models using robust statistical methods. Also provided are comprehensive overviews of volcanic phenomena, and a full glossary of both volcanological and statistical terms. Statistics in Volcanology is essential reading for advanced undergraduates, graduate students, and research scientists interested in this multidisciplinary field.

Download or read book Volcanoes written by John P. Lockwood and published by John Wiley & Sons. This book was released on 2013-04-26 with total page 677 pages. Available in PDF, EPUB and Kindle. Book excerpt: Volcanoes are essential elements in the delicate global balance of elemental forces that govern both the dynamic evolution of the Earth and the nature of Life itself. Without volcanic activity, life as we know it would not exist on our planet. Although beautiful to behold, volcanoes are also potentially destructive, and understanding their nature is critical to prevent major loss of life in the future. Richly illustrated with over 300 original color photographs and diagrams the book is written in an informal manner, with minimum use of jargon, and relies heavily on first-person, eye-witness accounts of eruptive activity at both "red" (effusive) and "grey" (explosive) volcanoes to illustrate the full spectrum of volcanic processes and their products. Decades of teaching in university classrooms and fieldwork on active volcanoes throughout the world have provided the authors with unique experiences that they have distilled into a highly readable textbook of lasting value. Questions for Thought, Study, and Discussion, Suggestions for Further Reading, and a comprehensive list of source references make this work a major resource for further study of volcanology. Volcanoes maintains three core foci: Global perspectives explain volcanoes in terms of their tectonic positions on Earth and their roles in earth history Environmental perspectives describe the essential role of volcanism in the moderation of terrestrial climate and atmosphere Humanitarian perspectives discuss the major influences of volcanoes on human societies. This latter is especially important as resource scarcities and environmental issues loom over our world, and as increasing numbers of people are threatened by volcanic hazards Readership Volcanologists, advanced undergraduate, and graduate students in earth science and related degree courses, and volcano enthusiasts worldwide.

Available in PDF, EPUB and Kindle. Book excerpt: This impressive scientific resource presents up-to-date information on ten thousand years of volcanic activity on Earth. In the decade and a half since the previous edition was published new studies have refined assessments of the ages of many volcanoes, and several thousand new eruptions have been documented. This edition updates the book’s key components: a directory of volcanoes active during the Holocene; a chronology of eruptions over the past ten thousand years; a gazetteer of volcano names, synonyms, and subsidiary features; an extensive list of references; and an introduction placing these data in context. This edition also includes new photographs, data on the most common rock types forming each volcano, information on population densities near volcanoes, and other features, making it the most comprehensive source available on Earth’s dynamic volcanism.
Download or read book Volc n de Colima written by Nick Varley and published by Springer. This book was released on 2019-02-14 with total page 313 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book represents a comprehensive coverage of the current state of knowledge of Volcán de Colima: its history, its eruptive mechanism, the generation and interpretation of monitoring data, and the risk presented to the local population. The volume pulls together the results of the most important studies of recent years from many areas of volcanology: the geology of its eruptive products; geophysical and geochemical studies of the signals measured that relate to the generation and movement of magma; experimental analysis of its internal processes and the social complexities relating to the risk imposed by future eruptions. Volcán de Colima is an important volcano: it has frequent large Plinian or sub-Plinian eruptions; its activity frequently switches between various regimes, which provides the opportunity to study these transitions from their cause to their impact; and it is a volcano which poses a significant threat to a large population.
