Seismic Instrumentation

Here is unique and comprehensive coverage of modern seismic instrumentation, based on the authors’ practical experience of a quarter-century in seismology and geophysics. Their goal is to provide not only detailed information on the basics of seismic instruments but also to survey equipment on the market, blending this with only the amount of theory needed to understand the basic principles. Seismologists and technicians working with seismological instruments will find here the answers to their practical problems. Instrumentation in Earthquake Seismology is written to be understandable to the broad range of professionals working with seismological instruments and seismic data, whether students, engineers or seismologists. Whether installing seismic stations, networks and arrays, working and calibrating stationary or portable instruments, dealing with response information, or teaching about seismic instruments, professionals and academics now have a practical and authoritative sourcebook. Includes: SEISAN and SEISLOG software systems that are available from http://extras.springer.com and http://www.geo.uib.no/seismo/software/software.html

This book is a collection of three papers authored by Dr. Raman K Attri between 1999 to 2001. The book presents early-career scientific work by the author as a scientist at a research organization. The book provides a theoretical and conceptual understanding of concepts and principles for detection and measurements of the seismic signals. The earthquake phenomenon is one of the most unpredictable and often devastating natural events. Sophisticated and advanced technologies are being used for monitoring the seismic activities across the world and efforts are being put in place to develop prediction models. The theory behind the design of sensors, instrumentation and monitoring system is usually not known to electronics and software engineers upfront. The papers included in this book provide such basic guidance to electronics and software design engineers and equip them with the key computational and algorithmic principles based on the underlying theory of seismic activities. These design techniques are fundamental to designing sophisticated seismic instrumentation and earthquake monitoring systems. The first paper presents a simplified mathematical framework of the seismic events and backend computational software logic that will enable software engineers to develop a customized seismic analysis and computation software. The second paper presents a simplified description of various earthquake parameters of interest to a seismologist and how these complex parameters are computed using equations. In the third paper, a visionary concept is presented to integrate geo-scientific instrumentation equipment such as seismic measurement systems to information technology network that would create a centralized web-enabled database that would allow transmitting the data acquired by geographically distributed but networked observatories to better predict or alert about the phenomena like earthquakes.

Seismic instrumentation systems are important elements for plant safety. They provide crucial information for the assessment of safety required to restart a plant after a shutdown caused by an earthquake. This publication presents information and experience related to the development of seismic instrumentation systems and the utilization of data recorded by them, based on recent seismic events. The publication is intended to be a reference for developing effective post-earthquake actions/procedures. It describes the typologies of seismic instrumentation systems and their application for obtaining 'earthquake levels' and 'damage indicating parameters' that are used to predict the extent of seismic damage caused by the recorded earthquake motions. It complements IAEA Safety Standards Series No. NS-G-1.6, Seismic Design and Qualification for Nuclear Power Plants, and Safety Reports Series No. 66, Earthquake Preparedness and Response for Nuclear Power Plants, as a technical publication relevant to seismic safety for new and existing nuclear installations.

This Safety Guide provides recommendations on how to meet the applicable safety requirements in relation to the design aspects of new nuclear installations subjected to seismic hazard. These recommendations focus on the consistent application of methods and procedures, in accordance with best practice, for seismic analysis, design, testing and qualification of structures, systems and components. New recommendations include applications of seismic isolation systems, the seismic margin to be achieved by the design and application of the graded approach. This Safety Guide is intended for use by organizations involved in the seismic design of nuclear installations, in analysis, verification and review, and in the provision of technical support, as well as by regulatory bodies.
