Book Description

Digital signal processing has become an integral part of observational seismology. Seismic waveforms and the parameters commonly extracted from them are strongly influenced by the effects of numerous filters, both within the earth and within the recording system. With the advent of numerous software tools for the processing of digital seismograms, seismologists have unprecedented power in extracting information from seismic records. These tools are often based on sophisticated theoretical aspects of digital signal processing which, to be used properly, need to be understood. This book is aimed at observational seismologists and students in geophysics trying to obtain a basic understanding of those aspects of digital signal processing that are relevant to the interpretation of seismograms. It covers the basic theory of linear systems, the design and analysis of simple digital filters, the effect of sampling and A/D conversion, the calculation of `true ground motion', and the effects of seismic recording systems on parameters extracted from digital seismograms. It contains numerous examples and exercises together with their solutions. ... Read more

Of Poles and Zeros
This is an excellent introduction to modern seismic measurement systems. Basically all what you need to know is covered here. Starting from functioning of seismometer, analog-to-digital techniques and digital filtering. All from the point of view of seismological interests, i.e. everything is all the time nicely linked with seismological practices which other "signal and systems" books obviously lack. Also the CD included is very educative when learning what poles and zeros actually mean.

Pictures could be a bit better from time to time. It seems that straight window-captures have been used when some further image processing would have been required.

Nevertheless, this is a must for any seismologist dealing with measuring systems. ... Read more

Book Description

Hardbound. This book seeks to explore seismic phenomena in elastic media and emphasizes the interdependence of mathematical formulation and physical meaning. The purpose of this title - which is intended for senior undergraduate and graduate students as well as scientists interested in quantitative seismology - is to use aspects of continuum mechanics, wave theory and ray theory to describe phenomena resulting from the propagation of waves.

The book is divided into three parts: Elastic continua, Waves and rays, and Variational formulation of rays. In Part I, continuum mechanics are used to describe the material through which seismic waves propagate, and to formulate a system of equations to study the behaviour of such material. In Part II, these equations are used to identify the types of body waves propagating in elastic continua as well as to express their velocities and displacements in terms of the properties of these continua. To solve the equati ... Read more

Book Description

An Introduction to Mining Seismology describes comprehensively the modern methods and techniques used to monitor and study seismicity and rockbursts in mines. Key case histories from various worldwide mining districts clearly illustrate and skillfully emphasize the practical aspects of mining seismology. This text is intended as a handbook for geophysicists and mining and rock mechanics engineers working at mines. It will alsoserve as an essential reference tool for seismologists working at research institutions on local seismicity not necessarily induced by mining.

Key Features
* Presents a comprehensive description of seismicity induced by mining worldwide
* Provides information on optimum network planning and seismic event location procedures in deep mines
* Covers a broad array of topics including focal mechanism, moment tensor, and double-couple versus non-double-couple seismic events in mines
* Includes data on source parameters and scaling relations for seismic events in mines ... Read more

Book Description

In the past 500 years, the Caribbean region has had devastating tsunamis causing incalculable damage. It is an area of relatively high seismicity, and although tsunamis are not the chief natural hazard, they have the potential to produce catastrophic regional disasters.

Today the necessity for awareness is of paramount importance. Tectonic forces continually build stress - until the inevitable release of strain that may trigger a tsunamigenic earthquake. The lack of a major tsunami in the past 57 years is due to a relative lack of relief of built-up energy, and the potential extent of the stress release grows as time elapses. The long period without relief of seismic stress buildup only increases the ominous threat of a devastating tsunami that could result from a sudden seafloor cataclysm.Caribbean Tsunamis - A 500-Year History from 1498--1998 broadly characterizes the nature of tsunamis in the Caribbean Sea, while bearing in mind both scientific aspects as well as potential interest by the many governments and populations likely to be affected by the hazard. Comprehension of the nature of tsunamis and past effects is crucial for the awareness and education of populations at risk.Audience: This book provides a thorough, yet highly accessible review of tsunamis in the Caribbean. It is of interest not only to tsunami and natural hazards specialists at academia and governmental institutes, but also to policy makers and to the general public. ... Read more
