Methods and Applications of Signal Processing in Seismic Network Operations

Tetsuo Takanami, Genshiro Kitagawa (auth.)3540437185, 9783540437185

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.
