Takanami T., Kitagawa G. Methods and Applications of Signal Processing in Seismic Network Operations

Springer, 2003. — 266 p.This book should prove useful for seismologists and engineers involved in seismic network operations. Recent pro~ess in the measurement and digital signal processing devices has made it possible to obtain a vast amount of earthquake data on seismic networks. Since 1979 several areas in Japan have been specified as priority observation areas and well-equipped nation-wide seismological network systems have been installed. The advances in earthquake monitoring and seismic network operation are expected have a significant effect on the realization of earthquake prediction. In practice, however, the earth's surface is under the continuous influences of natural forces such the effect of the past earthquakes, wave, wind, tide, air pressure, precipitation and variety of human induced sources. Therefore it is almost impossible to describe response to these noise inputs precisely. The development of a proper methodology, particular a statistical method, is indispensable for a vast amount of seismic data in and reliable automatic processing.Extraction of Small Seismic Signal by State Space Modeling
