ABSTRACT
This study illustrates
presents a set of the Long – Term Geoelectric Potential (LTGP) measurements
that are collected for experimental investigation in Western Greece during a
five–year period (1993 – 1997). During this period, many major destructive
earthquake events occurred that caused human casualties and extended material
damages. The collection and processing of geoelectric measurements was done by
an automated data acquisition system at the Seismological Laboratory of the
University of Patras, Greece. This novel study considers seismic activity of
this area as a typical linear dynamic system and the dynamic relationship
between the magnitude of earthquakes and Long – Term Geoelectric Potential
signals is inferred by the Recursive Least Square algorithm. The results are
encouraging and show that linear dynamic systems, which are widely used in
modern control theory, can describe efficiently the dynamic behavior of seismic
activity and become a useful interpretative tool of seismic phenomenon.
