Ebook: Methods and Applications of Signal Processing in Seismic Network Operations

Methods and applications of signal processing in seismic network operations are described by the specialists in the fields of signal processing problems in seismology, in particular in the the current seismological networks world. This book addresses successful applications of signal processing in the seismic networks and the time series analysis. The practices included in this book are also related to various stages of development of seismic networks and time series analysis. This book is a valuable handbook for seismologists and engineers working in the seismic network as well as being a reference book for university level researchers in the field of signal processing in seismology.

This book deals with various theoretical and practical methods for real-time automatic signal processing in local (and regional) seismic networks and associated software developments, including extraction of small seismic signal from noisy observation by piecewise modeling and self-organizing state space modeling, determination of arrival time of S wave by locally multivariate stationary AT modeling, automatic interpretation of seismic signal by combining cumulativ sum and simulative annealing (CUSUM-SA), AR-filtering for local and teleseismic events, the currently high sensitivity seismic network running in Japan (Hi-net), PC-based computer package for automatic detection and location of earthquakes, real-time automatic seismic data-processing in seismic network running in eastern Sicily (Italy), the SIL (South Iceland Lowland) seismological data acquisition system and routine analysis in Iceland and Sweden.
