Frequent updating of existing interpretation codes and routines is a prerequisite for modern seismogram interpretation and research. The primary goal of this book is to present in a rather tutorial form all the necessary information and techniques pertinent to essential seismogram interpretation. The treatment is descriptive rather then mathematical, and emphasis is placed on practical aspects, especially for the benefit of students and junior seismogram interpreters affiliated to seismographic stations and observatories. Those workers more knowledgeable in seismology, and curious enough in the detailed deciphering of seismogram peculiarities, will also find the presentation useful. The book is divided into two parts: a verbal description (Chapters 1-6) and a collection of 55 plates (Chapter 7) with interpretations. The verbal description explains in a rather elementary form the most fundamental physical phenomena relevant to seismogram appearance. The collection of plates exhibits a large variety of seismogram examples, and the corresponding interpretations cover different seismic sources (tectonic and volcanic earthquakes, underground explosions, cavity collapse, sonic booms), wave types, epicentral distances, focal depths and recording instruments (analog, digital, short- and long-period, broad band). The book compliments older manuals in that both analog and digital records are considered. Seismograms from more traditional narrow-band as well as from modern, broad-band instruments are displayed. Tectonic and volcanic earthquakes are represented, and the exhibited seismograms form a worldwide collection of records acquired from seismographic stations located in North and Central America, Asia, Europe and New Zealand, i.e. in various geological and tectonic environments. Terminology and usage of definition does vary among agencies in different parts of the world; that used in this book is common to Europe.

"The Wenchuan Earthquake of 2008: Anatomy of a Disaster" gives a detailed account of the damage, seismology and tectonics of the event and discusses earthquake prediction, seismic hazard and risk management, the creation and implementation of building codes, and new practices used in rescue, relief and reconstruction. It will be of significant interest to researchers and practitioners engaged in seismology, geophysics, engineering, the social sciences, and disaster management and recovery. It also offers a valuable new and unique Chinese perspective with many insights for future mitigation of earthquake risk. Professor Yong Chen works for the China Earthquake Administration; Dr David C. Booth works for the British Geological Survey.

A comprehensive overview of a catastrophic earthquake which occurred at Tangshan in northeastern China in l976. In addition to a presentation of various aspects of the earthquake, including the geological structures of the area, a history of the seismicity, and the various hazards from an engineering viewpoint, the sociological problems are also discussed. The book presents the results of 20 years research by Chinese scientists, in the field of earthquake prediction, and notes the difficulties they are still facing.

Developments in Earthquake Engineering have focussed on the capacity and response of structures. They often overlook the importance of seismological knowledge to earthquake-proofing of design. It is not enough only to understand the anatomy of the structure, you must also appreciate the nature of the likely earthquake. Seismic design, as detailed in this book, is the bringing together of Earthquake Engineering and Engineering Seismology. It focuses on the seismological aspects of design – analyzing various types of earthquake and how they affect structures differently. Understanding the distinction between these earthquake types and their different impacts on buildings can make the difference between whether a building stands or falls, or at least to how much it costs to repair. Covering the basis and basics of the major international codes, this is the essential guide for professionals working on structures in earthquake zones around the world.

The New Madrid earthquakes of 1811–12 were the strongest temblors in the North American interior in at least the past five centuries. From the Great Plains to the Atlantic Coast and from the Great Lakes to the Gulf of Mexico, a broad cast of thinkers struggled to explain these seemingly unprecedented natural phenomena. They summoned a range of traditions of inquiry into the natural world and drew connections among signs of environmental, spiritual, and political disorder on the cusp of the War of 1812. Drawn from extensive archival research, Convulsed States probes their interpretations to offer insights into revivalism, nation remaking, and the relationship between religious and political authority across Native nations and the United States in the early nineteenth century. With a compelling narrative and rigorous comparative analysis, Jonathan Todd Hancock uses the earthquakes to bridge historical fields and shed new light on this pivotal era of nation remaking. Through varied peoples' efforts to come to grips with the New Madrid earthquakes, Hancock reframes early nineteenth-century North America as a site where all of its inhabitants wrestled with fundamental human questions amid prophecies, political reinventions, and war.

An Introduction to Seismology, Earthquakes and Earth Structures is an introduction to seismology and its role in the earth sciences, and is written for advanced undergraduate and beginning graduate students. The fundamentals of seismic wave propagation are developed using a physical approach and then applied to show how refraction, reflection, and teleseismic techniques are used to study the structure and thus the composition and evolution of the earth. The book shows how seismic waves are used to study earthquakes and are integrated with other data to investigate the plate tectonic processes that cause earthquakes. Figures, examples, problems, and computer exercises teach students about seismology in a creative and intuitive manner. Necessary mathematical tools including vector and tensor analysis, matrix algebra, Fourier analysis, statistics of errors, signal processing, and data inversion are introduced with many relevant examples. The text also addresses the fundamentals of seismometry and applications of seismology to societal issues. Special attention is paid to help students visualize connections between different topics and view seismology as an integrated science. An Introduction to Seismology, Earthquakes, and Earth Structure gives an excellent overview for students of geophysics and tectonics, and provides a strong foundation for further studies in seismology. Multidisciplinary examples throughout the text - catering to students in varied disciplines (geology, mineralogy, petrology, physics, etc.). Most up to date book on the market - includes recent seismic events such as the 1999 Earthquakes in Turkey, Greece, and Taiwan). Chapter outlines - each chapter begins with an outline and a list of learning objectives to help students focus and study. Essential math review - an entire section reviews the essential math needed to understand seismology. This can be covered in class or left to students to review as needed. End of chapter problem sets - homework problems that cover the material presented in the chapter. Solutions to all odd numbered problem sets are listed in the back so that students can track their progress. Extensive References - classic references and more current references are listed at the end of each chapter. A set of instructor's resources containing downloadable versions of all the figures in the book, errata and answers to homework problems is available at: http://levee.wustl.edu/seismology/book/. Also available on this website are PowerPoint lecture slides corresponding to the first 5 chapters of the book.
