Available in PDF, EPUB and Kindle. Book excerpt: This chapter discusses the unique characteristics of the volcanic eruptions in Indonesia. We know that Indonesia has 147 volcanoes and 76 of them are active volcanoes and spread along the islands of Java, Lesser Sunda, Sumatra, and Celebes. The characteristics of Indonesian volcanoes are quite unique in terms of the formation process, eruption phenomenon, and the resulting natural disasters. Most volcanoes in Indonesia consist of stratovolcanoes, but this does not mean that the resulting eruptions are always explosive and they have a long period. This can be seen from the activity of Semeru that always erupts effusively every day, Sinabung that has a very short eruption period, Tangkuban Perahu eruption that occurs suddenly with the lack of early signs, and Merapi and Kelud that have eruption period that is getting shorter. Based on the results of our study it can be known that the types of volcanic eruption are influenced by the structure of the constituent rocks of the volcanoes. However, the presence of external control factors in the form of large-scale earthquakes will affect their periodicity. The large earthquakes can affect the stability of the magma chamber that can trigger a premature eruption.

Book excerpt: This book contains 12 chapters dealing with the studies on volcanoes, their geological and geophysical setting, the theoretical aspects and the numerical modeling on volcanoes, the applications of volcanoes to the industry, and the impact of volcanoes on the human health, in different geological settings and using several techniques and methods, including the volcanology, the seismology, the statistical methods to assess the correlation between seismic and volcanic activity (modified Ripley's K-function to regional seismicity), the field geological survey of volcanic successions, the analytical methods of petrologic analysis, the petrography of the volcanic rocks with the individuation of the modal compositions of volcanic rocks and their comparison with major elements and trace elements in variation diagrams, and the argon isotopic measurements performed through the peak height comparison (unspiked) method. The oceanographic methods have also been applied to case studies of submarine volcanic edifices located in the Canary Islands (Atlantic Ocean), including the sampling of the water column with a conductivity-temperature-depth (CTD) sensor rosette with 24 Niskin bottles, in order to determinate key physical and chemical parameters, such as the total-scale pH, the total dissolved inorganic carbon (C), the total alkalinity (A), the temperature, the salinity, and the dissolved oxygen. Problems of volcanic risk mitigation have also been treated, regarding the eruption disasters in Indonesia, a country where a high number of people live next to the volcanoes, and characterized by the lack of public awareness of the eruption disasters. Petrographic methods have been successfully applied to the study of the Cretaceous magmatism of the layered gabbroids of the Chukotka region (Pekulney Ridge, Russia), and geodynamic implications have been successfully established through geological and petrographic studies. The relationships among the mantle wedge, the convective heat and mass transfer, the infiltration metasomatism, the zoning, and the mathematical models have been applied to the comprehension of complex volcanic areas through the theoretical aspects of volcanic studies on magmatic chambers coupled with numerical modeling, including finite element models (FEMs) in the individuation of volcanic deformations.
Download or read book Introduction to Volcanic Seismology written by Vyacheslav M Zobin and published by Elsevier. This book was released on 2011-12-08 with total page 501 pages. Available in PDF, EPUB and Kindle. Book excerpt: Volcanic seismology represents the main, and often the only, tool to forecast volcanic eruptions and to monitor the eruption process. This book describes the main types of seismic signals at volcanoes, their nature and spatial and temporal distributions at different stages of eruptive activity. Following from the success of the first edition, published in 2003, the second edition consists of 19 chapters including significant revision and five new chapters. Organized into four sections, the book begins with an introduction to the history and topic of volcanic seismology, discussing the theoretical and experimental models that were developed for the study of the origin of volcanic earthquakes. The second section is devoted to the study of volcano-tectonic earthquakes, giving the theoretical basis for their occurrence and swarms as well as case stories of volcano-tectonic activity associated with the eruptions at basaltic, andesitic, and dacitic volcanoes. There were 40 cases of volcanic eruptions at 20 volcanoes that occurred all over the world from 1910 to 2005, which are discussed. General regularities of volcano-tectonic earthquake swarms, their participation in the eruptive process, their source properties, and the hazard of strong volcano-tectonic earthquakes are also described. The third section describes the theoretical basis for the occurrence of eruption earthquakes together with the description of volcanic tremor, the seismic signals associated with pyroclastic flows, rockfalls and lahars, and volcanic explosions, long-period and very-long-period seismic signals at volcanoes, micro-earthquake swarms, and acoustic events. The final section discuss the mitigation of volcanic hazard and include the methodology of seismic monitoring of volcanic activity, the examples of forecasting of volcanic eruptions by seismic methods, and the description of seismic activity in the regions of dormant volcanoes. This book will be essential for students and practitioners of volcanic seismology to understand the essential elements of volcanic eruptions. Provides a comprehensive overview of seismic signals at different stages of volcano eruption. Discusses dozens of case histories from around the world to provide real-world applications. Illustrations accompany detailed descriptions of volcano eruptions alongside the theories involved.
Download or read book Volcanoes written by Alwyn Scarth and published by CRC Press. This book was released on 1994-06-30 with total page 288 pages. Available in PDF, EPUB and Kindle. Book excerpt: Why do volcanoes erupt, and in so many different ways? What happens when a volcano erupts in the sea? How can eruptions be predicted? These are a few of the questions addressed in this wide-ranging introduction to volcanoes. Assuming little background knowledge, and providing a comprehensive glossary explaining technical terms, this title deals with all aspects of volcanic features and processes. It examines them as distinctive, and often dramatic, features of the landscape, as well as potential sources of danger to human beings.; Volcanoes provide an exciting way in which to analyze some of the major geological processes. The author sets them in their world context and explains their formation, especially in relation to the many styles of eruption, and the multitude of volcanic landscape forms that result. Some major eruptions are selected to illustrate this eruptive variety and the impact on surrounding populations. Distinctive landscape forms, from flows to cones and calderas, are described with reference to the "biographies" of the volcanoes. There are chapters devoted to stratovolcanoes, hydrovolcanic features and erosional processes. A final chapter examines the latest methods of predicting volcanic eruptions and moderating their effects.; Drawing on an unusually wide range of sources in the French, Spanish and Portuguese literature, as well as English, the author presents examples and illustrations from around the world, including the Aegean, the French West Indies, the American West, the Azores and the Canary Islands, Italy and central France. He has also translated various eye-witness accounts of volcanic events and has included a revised version of Pliny's account of the eruption of Vesuvius.
Download or read book Observing the Volcano World written by Carina J. Fearnley and published by Springer. This book was released on 2018-07-14 with total page 771 pages. Available in PDF, EPUB and Kindle. Book excerpt: This open access book provides a comprehensive overview of volcanic crisis research, the goal being to establish ways of successfully applying volcanology in practice and to identify areas that need to be addressed for future progress. It shows how volcano crises are managed in practice, and helps to establish best practices. Consequently the book brings together authors from all over the globe who work with volcanoes, ranging from observatory volcanologists, disaster practitioners and government officials to NGO-based and government practitioners to address three key aspects of volcanic crises. First, the book explores the unique nature of volcanic hazards, which makes them a particularly challenging threat to forecast and manage, due in part to their varying spatial and temporal characteristics. Second, it presents lessons learned on how to best manage volcanic events based on a number of crises that have shaped our understanding of volcanic hazards and crises management. Third, it discusses the diverse and wide-ranging aspects of communication involved in crises, which merge old practices and new technologies to accommodate an increasingly challenging and globalised world. The information and insights presented here are essential to tapping established knowledge, moving towards more robust volcanic crises management, and understanding how the volcanic world is perceived from a range of standpoints and contexts around the globe.
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 Religious Responses to Earthquake and Volcanic Eruption Disasters written by David Chester and published by Taylor & Francis. This book was released on 2024-07-26 with total page 214 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book argues that, although secular and religious perspectives on disasters have often conflicted, today there are grounds for believing that the world’s major faiths have much to contribute to the processes of post-disaster recovery and future disaster risk reduction (DRR). It seeks to demonstrate how contemporary dialogues between theologians, disaster scholars and policymakers are defining new ways of working together. These explore how the resources of religious communities, e.g. buildings, human resources and finance, may be used to foster successful policies of DRR, particularly in the aftermath of earthquakes and volcanic eruptions. Musing on the relationships between religion and disasters has occurred for millennia and has affected many societies worldwide. In societies where the world’s major religions – Buddhism, Christianity, Hinduism, Islam, Judaism and Shinto – have been and remain dominant, attempting to find supernatural explanations for disasters has occurred throughout history and there have been many theologies seeking to explain why people suffer losses. It is argued that developments both within these traditions of faith and in how disasters are understood by the hazard research community of researchers and planners have allowed a new modus vivendi to emerge which emphasises both a recognition of religious worldviews by academic writers and disaster planners on the one hand, and a desire by people of faith and their leaders to be more fully committed to the goals of DRR. The book will appeal to those who are interested in the interface between disasters and theology across the principal religions of the world. This includes researchers and students in geology, geography, theology and religious studies. It will also be useful for specialist academic audience and the educated general reader.

Download or read book Encyclopedia of Modern Coral Reefs written by David Hopley and published by Springer Science & Business Media. This book was released on 2010-11-26 with total page 1226 pages. Available in PDF, EPUB and Kindle. Book excerpt: Coral reefs are the largest landforms built by plants and animals. Their study therefore incorporates a wide range of disciplines. This encyclopedia approaches coral reefs from an earth science perspective, concentrating especially on modern reefs. Currently coral reefs are under high stress, most prominently from climate change with changes to water temperature, sea level and ocean acidification particularly damaging. Modern reefs have evolved through the massive environmental changes of the Quaternary with long periods of exposure during glacially lowered sea level periods and short periods of interglacial growth. The entries in this encyclopedia condense the large amount of work carried out since Charles Darwin first attempted to understand reef evolution. Leading authorities from many countries have contributed to the entries covering areas of geology, geography and ecology, providing comprehensive access to the most up-to-date research on the structure, form and processes operating on Quaternary coral reefs.
