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.

This book was released on 2013-04-28 with total page 185 pages. Available in PDF, EPUB and Kindle. Book excerpt: We live in a changing world with multiple and evolving threats to national security, including terrorism, asymmetrical warfare (conflicts between agents with different military powers or tactics), and social unrest. Visually depicting and assessing these threats using imagery and other geographically-referenced information is the mission of the National Geospatial-Intelligence Agency (NGA). As the nature of the threat evolves, so do the tools, knowledge, and skills needed to respond. The challenge for NGA is to maintain a workforce that can deal with evolving threats to national security, ongoing scientific and technological advances, and changing skills and expectations of workers. Future U.S. Workforce for Geospatial Intelligence assesses the supply of expertise in 10 geospatial intelligence (GEOINT) fields, including 5 traditional areas (geodesy and geophysics, photogrammetry, remote sensing, cartographic science, and geographic information systems and geospatial analysis) and 5 emerging areas that could improve geospatial intelligence (GEOINT fusion, crowdsourcing, human geography, visual analytics, and forecasting). The report also identifies gaps in expertise relative to NGA's needs and suggests ways to ensure an adequate supply of geospatial intelligence expertise over the next 20 years.

This book covers a number of key concepts and theories central to this field to equip readers with detailed information about the diverse aspects of volcanology. Various advancements in this field are glanced at and their applications as well as ramifications are looked at in detail. Coherent flow of topics, student-friendly language and extensive use of examples make this book an invaluable source of knowledge.
Download or read book Methodologies and Applications of Prestack Waveform Inversion Reverse Time Migration and Artificial Intelligence in Seismic Exploration written by Lingxiao Jia and published by . This book was released on 2021 with total page 136 pages. Available in PDF, EPUB and Kindle. Book excerpt: Seismic migration and inversion describe a class of closely related processes sharing common objectives and underlying physical principles. Reverse time migration (RTM) is a migration method that can provide high quality images for structures with steep dips and strong horizontal velocity variations. Prestack waveform inversion (PWI) is an inversion method that is a practical choice for subsurface reservoir description using the current computational resources. Although RTM and PWI provide a depth image and subsurface properties, interpreting subsurface structures from the seismic images can be challenging, especially when the geology is complex. Use of automated methods using the artificial intelligence (AI) recently became popular for interpreting such complex geology. This dissertation focuses on the applications of PWI, RTM, and AI for interpreting seismic data using three proposed methods. The first method is a new methodology and workflow for a nonlinear prestack isotropic elastic waveform inversion, which we call data driven inversion, meaning that we derive the initial model entirely from the seismic data without using any well information. The second method is a joint iterative workflow that combines RTM and PWI, where PWI is run on the common image gathers (CIGs) obtained from RTM, followed by another pass of RTM, taking the updated models from PWI as input. This method allows for automatic model updates to improve the accuracy of both depth image and subsurface elastic model. The third method is an AI based semi-supervised training workflow for salt recognition, which allows the predicted model to iteratively improve as more and more information is distilled from the unlabeled data into the model. For each iteration, the model obtained from previous iteration is used for generating pseudo labels for the unlabeled data. This automated consecutive data distillation allows the model prediction to improve with iteration, without any need for human intervention. All these methods were validated using synthetic data and then applied to real datasets.

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.
