Natural Hazards


Book Description

Over the years, the interactions between land, ocean, biosphere and atmosphere have increased, mainly due to population growth and anthropogenic activities, which have impacted the climate and weather conditions at local, regional and global scales. Thus, natural hazards related to climate changes have significantly impacted human life and health on different spatio-temporal scales and with socioeconomic bearings. To monitor and analyze natural hazards, satellite data have been widely used in recent years by many developed and developing countries. In an effort to better understand and characterize the various underlying processes influencing natural hazards, and to carry out related impact assessments, Natural Hazards: Earthquakes, Volcanoes, and Landslides, presents a synthesis of what leading scientists and other professionals know about the impacts and the challenges when coping with climate change. Combining reviews of theories and methods with analysis of case studies, the book gives readers research information and analyses on satellite geophysical data, radar imaging and integrated approaches. It focuses also on dust storms, coastal subsidence and remote sensing mapping. Some case studies explore the roles of remote sensing related to landslides and volcanoes. Overall, improved understanding of the processes leading to these hazardous events will help scientists predict their occurrence. Features Provides information on the physics and physical processes of natural hazards, their monitoring and the mapping of damages associated with these hazards Explains how natural hazards are strongly associated with coupling between land–ocean–atmosphere Includes a comprehensive overview of the role of remote sensing in natural hazards worldwide Examines risk assessment in urban areas through numerical modelling and geoinformation technologies Demonstrates how data analysis can be used to aid in prediction and management of natural hazards




Geomechanics and Geodynamics of Rock Masses


Book Description

Geomechanics and Geodynamics of Rock Masses contains contributions presented at EUROCK 2018, the 2018 International Symposium of the International Society for Rock Mechanics (ISRM 2018, Saint Petersburg, Russia, 22-26 May 2018). Dedicated to recent advances and achievements in the fields of geomechanics and geotechnology, the main topics of the book include: - Physical and mechanical properties of fractured rock (laboratory testing and rock properties, field measurements and site investigations) - Geophysics in rock mechanics - Rock mass strength and failure - Nonlinear problems in rock mechanics - Effect of joint water on the behavior of rock foundation - Numerical modeling and back analysis - Mineral resources development: methods and rock mechanics problems - Rock mechanics and underground construction in mining, hydropower industry and civil engineering - Rock mechanics in petroleum engineering - Geodynamics and monitoring of rock mass behavior - Risks and hazards - Geomechanics of technogenic deposits Geomechanics and Geodynamics of Rock Masses will be of interest to researchers and professionals involved in the various branches of rock mechanics and rock engineering. EUROCK 2018, organized by the Saint Petersburg Mining University, is a continuation of the successful series of ISRM symposia in Europe, which began in 1992 in Chester, UK.




Biological Effects of Electromagnetic Fields


Book Description

Reporting new results, this book covers the subject of biological effects of EMF in its entirety. Experimental verification of the theoretical results is given when at all possible, and the book is expected to open new areas of research, providing material for university course creation.







Natural Hazards


Book Description

This special volume contains a selection of papers that were presented as part of the Seventh International Symposium on Natural and Man-Made Hazards (HAZARDS-98), held in Chania, Crete Island, Greece, during May 1998. The Symposium attracted broad international interest because many cases of natural disaster events, such as earthquakes, tsunamis, storm surges, forest fires, etc., that occurred in several parts of the world during the 1990s were presented not only for their physics but also from the point of view of their impact on society and their environmental consequences. Among these cases are the 1997 Red River Valley flood in Canada and the large earthquake of 18 November 1997, in Zakynthos, Greece. In addition, the volume contains contributions that apply advanced statistical methods and artificial intelligence techniques, such as GIS, and systems analysis to approach the description of physical processes, the discrimination of experimental data and the assessment and management of risk. Audience: This volume forms an excellent reference for scientists, students, engineers, the insurance industry, authorities specializing in public safety and natural hazards preparedness and mitigation plans.
