Earthquake Hazard Assessment


Book Description

This book represents a significant contribution to the area of earthquake data processing and to the development of region-specific magnitude correlations to create an up-to-date homogeneous earthquake catalogue that is uniform in magnitude scale. The book discusses seismicity analysis and estimation of seismicity parameters of a region at both finer and broader levels using different methodologies. The delineation and characterization of regional seismic source zones which requires reasonable observation and engineering judgement is another subject covered. Considering the complex seismotectonic composition of a region, use of numerous methodologies (DSHA and PSHA) in analyzing the seismic hazard using appropriate instruments such as the logic tree will be elaborated to explicitly account for epistemic uncertainties considering alternative models (for Source model, Mmax estimation and Ground motion prediction equations) to estimate the PGA value at bedrock level. Further, VS30 characterization based on the topographic gradient, to facilitate the development of surface level PGA maps using appropriate amplification factors, is discussed. Evaluation of probabilistic liquefaction potential is also explained in the book. Necessary backgrounds and contexts of the aforementioned topics are elaborated through a case study specific to India which features spatiotemporally varied and complex tectonics. The methodology and outcomes presented in this book will be beneficial to practising engineers and researchers working in the fields of seismology and geotechnical engineering in particular and to society in general.




Natural and Anthropogenic Disasters


Book Description

The major challenges of the 21st century faced by human beings are how to achieve water security, food security, energy security and environmental security. Owing to enhanced natural/anthropogenic disasters worldwide, these challenges become much more complicated and daunting especially for developing countries. Therefore, it is important to highlight the risk of different disasters as well as the modern tools and techniques for minimizing disaster incidence and losses. Disaster management being highly multidisciplinary in nature, a comprehensive book dealing with different aspects of disaster management, and encompassing important disasters faced by humankind is presently not available. This book is an attempt to fulfill this gap. It provides clear, comprehensive, and up-to-date information about different facets of disaster management along with salient case studies. The book highlights the current status of disaster management focusing on developing nations, discusses vital issues such as climate change and sustainable development, modern approaches and tools/techniques, and the challenges of and future R&D needs for sustainable disaster management.




Microearthquake Seismology and Seismotectonics of South Asia


Book Description

This volume is the outcome of about 30 years of research in the field of earthquake seismology in various parts of South Asia. It comprehensively deals with topics raning from plate tectonics to seismic waves in general. State-of-the-art techniques in earthquake location/relocation, fault plane solution, waveform inversion, seismic tomography, fractals etc. are discussed, and the results are interpreted in terms of seismic source processes in the region.




Earthquakes


Book Description

The ultimate introduction to seismology, written by distinguished scholar and Professor Bruce Bolt, of the University of California, Berkeley, this newly updated edition will provide the best foundation in the field for your introductory students.







Earth-Shattering Events: Earthquakes, Nations, and Civilization


Book Description

"A truly welcome and refreshing study that puts earthquake impact on history into a proper perspective." --Amos Nur, Emeritus Professor of Geophysics, Stanford University, California, and author of Apocalypse: Earthquakes, Archaeology, and the Wrath of God Since antiquity, on every continent, human beings in search of attractive landscapes and economic prosperity have made a Faustian bargain with the risk of devastation by an earthquake. Today, around half of the world’s largest cities – as many as sixty – lie in areas of major seismic activity. Many, such as Lisbon, Naples, San Francisco, Teheran, and Tokyo, have been severely damaged or destroyed by earthquakes in the past. But throughout history, starting with ancient Jericho, Rome, and Sparta, cities have proved to be extraordinarily resilient: only one, Port Royal in the Caribbean, was abandoned after an earthquake. Earth-Shattering Events seeks to understand exactly how humans and earthquakes have interacted, not only in the short term but also in the long perspective of history. In some cases, physical devastation has been followed by decline. But in others, the political and economic reverberations of earthquake disasters have presented opportunities for renewal. After its wholesale destruction in 1906, San Francisco went on to flourish, eventually giving birth to the high-tech industrial area on the San Andreas fault known as Silicon Valley. An earthquake in Caracas in 1812 triggered the creation of new nations in the liberation of South America from Spanish rule. Another in Tangshan in 1976 catalysed the transformation of China into the world’s second largest economy. The growth of the scientific study of earthquakes is woven into this far-reaching history. It began with a series of earthquakes in England in 1750. Today, seismologists can monitor the vibration of the planet second by second and the movement of tectonic plates millimeter by millimeter. Yet, even in the 21st century, great earthquakes are still essentially "acts of God," striking with much less warning than volcanoes, floods, hurricanes, and even tornadoes and tsunamis.




The Indian World


Book Description




Earthquakes of the Indian Subcontinent


Book Description

This book highlights some of the interesting recent and historical earthquakes (1803 Uttarkashi, 1819 Kutch, 1897 Shillong, 1905 Kangra, 1934 Nepal-Bihar, 1950 Upper Assam, 1967 Koyna, 1993 Killari, 1997 Jabalpur, 2001 Bhuj, 2004 Sumatra-Andaman, 2005 Kashmir, and 2015 Nepal) that occurred in India and in the vicinity. The tectonic and geodynamic significance of the modern (after the advent of global network) earthquakes in relation to some of the historical earthquakes like the 1819 Kachchh and 1897 Shillong and 1934 Nepal-Bihar earthquakes in the light of newer understanding is discussed. It also contains detailed expositions of seismotectonics and mechanisms of each earthquake. It concludes with touching upon future earthquake hazard scenario in India in view of the present and past earthquakes.
