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.
