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.

Download or read book Merapi Volcano written by Ralf Gertisser and published by Springer Nature. This book was released on 2023-02-02 with total page 581 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides the first comprehensive compilation of cutting-edge research on Merapi volcano on the island of Java, Indonesia, one of the most iconic volcanoes in the world. It integrates results from both the natural (geology, petrology, geochemistry, geophysics, physical volcanology) and social sciences, and provides state-of-the-art information on volcano monitoring, the assessment of volcanic hazards, and risk mitigation measures. As one of Indonesia’s most active and dangerous volcanoes, Merapi is perhaps best known for its pyroclastic density currents, which are produced by gravitational or explosive lava dome failures (commonly referred to as Merapi-type nuées ardentes). Merapi’s eruptions have posed a persistent threat to life, property and infrastructure within the densely populated areas on the volcano’s flanks, as demonstrated most recently by catastrophic eruptions, which attracted worldwide media interest.

Available in PDF, EPUB and Kindle. Book excerpt: Fractional crystallization, magma mixing, assimilation of continental crust, and how those processes modify volatile budgets, control the evolution of magma. As a consequence, the understanding of these processes, their magnitudes, and timescales is critical for interpreting ancient magma systems, their eruptions, and the potential future volcanic activity. In this dissertation I present the results of three projects. The first explores how magmatic processes affect magma reservoirs and eruption dynamics. The second explores where in the storage system and how often these processes occur. The third explores how volatile budgets are modified by processes such as crystallization, mixing, and assimilation. Volcán Popocatépetl (central México) erupted ~14100 14C yr BP producing the Tutti Frutti Plinian Eruption (TFPE). The eruption tapped two different silicic magmas that mixed just prior and during the eruption. The influx of mass and volatiles generated during the mixing of both magmas overpressured the reservoir, which was weakened at the top. The weakened reservoir relaxed while magma was tapped and collapsed to form a caldera at the surface. Although it is known that fractional crystallization, mixing, and assimilation can greatly modify magmas, the frequency and intensity of these events is not known. I investigated the magmatic processes responsible for the evolution of magmas erupted during five Plinian events of Popocatépetl volcano. Results show that during the last 23 ky magma was stored in two different zones, and was variably modified by replenishments of mafic magma. Interestingly, little evidence for large mafic inputs triggering explosive eruptions was found. Each of these processes alters the abundances of volatiles and introduces different types of volatiles to the system. Hence, the volatile budget of magma can have a rich and complex history. To investigate how volatile budgets evolve in active magma systems, I analyzed the abundances of volatiles (H2O, CO2, F, Cl, and S) in numerous glass inclusions trapped in phenocrysts. Results show that the magmas that produced the last five Plinian eruptions at Popocatépetl volcano evolved by crystallization and magma mixing, assimilation of the local carbonate basement is not chemically appreciable. Mixing with mafic magmas added substantial CO2 and S to the system, dewatered the magma, yet produced little change in the F contents of the magmas.

Available in PDF, EPUB and Kindle. Book excerpt: Physical Geology is a vast subject and it is not possible to cover all aspects in one book. This book does not invent the wheel but merely put together sets of updated but concise material on Physical Geology with lots of illustrations. All illustrations are created by hand and give a real classroom feel to the book. Students or readers can easily reproduce them by hand. This is a book, where a diagram says it all. The book is divided into four parts. The first part “The Solar System and Cosmic Bodies” deals with elements of our Solar System and the cosmic bodies around it (like meteorites, asteroids, etc.). The second part “The Earth Materials” deals with Earth and its internal structure. The third part “The Hydrologic System” is more exhaustive and deals with the hydrological system of the Earth including Weathering and Mass Wasting, Streams, Groundwater, Karst, Glaciers, Oceans and Aeolian Processes and Landforms. The fourth and the final part “The Tectonic System” deals with different aspects of Plate Tectonics, Earthquakes and Volcanoes.

Download or read book Basaltic Volcanism written by Lindsay Ann Szramek and published by . This book was released on 2010 with total page 628 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mafic magma is the most common magma erupted at the surface of the earth. It is generated from partial melting of the mantle, which has been subdivided into end-members based on unique geochemical signatures. One reason these end members, or heterogeneities, exist is subduction of lithospheric plates back into the mantle. The amount of elements, such as Cl and K, removed during subduction and recycled into the deep mantle, is poorly constrained. Additionally, the amount of volatiles, such as Cl, that are recycled into the deep mantle will strongly affect the behavior of the system. I have looked at Cl and K in HIMU source melts to see how it varies. Cl/Nb and K/Nb suggest that elevated Cl/K ratios are the result of depletion of K rather than increased Cl recycled into the deep mantle. After the mantle has partially melted and mafic melt has migrated to the surface, it usually erupts effusively or with low explosivity because of its low viscosity, but it is possible for larger eruptions to occur. These larger, Plinian eruptions, are not well understood in mafic systems. It is generally thought that basalt has a viscosity that is too low to allow for such an eruption to occur. Plinian eruptions require fragmentation to occur, which means the melt must undergo brittle failure. This may occur if the melt ascends rapidly enough to allow pressure to build in bubbles without the bubbles expanding. To test this, I have done decompression experiments to try to bracket the ascent rate for two Plinian eruptions. One eruption has a fast ascent, faster than those seen in more silicic melts, whereas the other eruption is unable to be reproduced in the lab, however it began with a increased viscosity in the partly crystallized magma. After fragmentation and eruption, it is generally thought that tephra do not continue to crystallize. We have found that crystallinity increases from rim to core in two basaltic pumice. Textural data along with a cooling model has allowed us to estimate growth rates in a natural system, which are similar to experimental data.

Download or read book Volcanic Successions Modern and Ancient written by R. Cas and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 532 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of our aims in the book is to provide geologists with a sound basis for making their own well founded interpretations. For that reason we cover not only concepts about processes, and the nature of the products, but also methods and approaches that may be useful in analysing both modern and ancient successions. Most importantly, we treat the diversity of products in volcanic terrains as facies, and we use the method of facies analysis and interpretation as a means of constructing facies models for different volcanic settings. These models will, we hope, be useful as norms for comparison for workers in ancient terrains. The idea for this book came into being between 1981 and 1982 when J. V. W. came to Monash University to take up a Monash Postdoctoral Fellowship. During this period a short course on facies analysis in modern and ancient successions was put together, integrating J.V.W.'s extensive volcanological experience in numerous modern volcanic terrains with R.A.F.C.'s extensive sedimentological and volcanological experience in older volcanic and associated sedimentary successions in the Palaeozoic and Precambrian of Australia. The enthusiastic response from the participants to the first short course, taught in May 1982, and to subsequent annual re-runs, encouraged us to develop the short course notes into this book. The idea for both the short course and the book arose because we felt that there was no single source available that comprehensively attempted to address the problems of analysing, interpreting and understanding the complexity of processes, products and stratigraphy in volcanic terrains.

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 Volcanic Debris Avalanches written by Matteo Roverato and published by Springer Nature. This book was released on 2020-11-16 with total page 358 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents an overview of volcanic debris avalanche deposits, which are produced by partial volcanic edifice collapse, a catastrophic natural phenomenon. It has been 40 years since the volcanic debris avalanche associated with the 1980 eruption of Mount St. Helens, and our understanding of these events has grown considerably in the interim. Drawing on these advances, the book addresses all aspects of volcanic debris avalanches. Though previously overlooked in field-based geological and volcanological studies, these deposits are now known to be associated with most volcanoes and volcanic areas around the world. The book presents state-of-the-art ideas on the triggering and emplacement mechanisms of these events, supported by field and analogue studies, as well as new simulations tools and models used to determine their physical characteristic and hazards.
