Seismicity observed, at Methoni seismogenic area, Greece, after the analysis of the recorded Earth_s electric field of 21/2/2008_ 22/2/2008, at PYR, ATH and HIO monitoring sites, Greece

Abstract

The seismicity, which took place at the Methoni seismogenic area, in the time period of 20/2/2008 - 10/4/2008, is analyzed in terms of its location, time of occurrence and magnitude. Furthermore, it is compared to the tidal (T=14 days, T=1 day) lithospheric oscillation and to the epicentral area suggested by the analysis of the Earth_s electric field registered on 21-22/2/2008 by PYR, ATH and HIO monitoring sites. Moreover, a comparison is made between the actual seismic energy released, during the same time period (20/2/2008 - 10/4/2008) in this specific seismogenic region and the suggested one by the probabilistic single seismic event suggested that could occur in the time period of 28/2_ 1/3/2008. The overall analysis of the Methoni seismic event reveals the validity of the used physical models: of the lithospheric oscillation, of the lithospheric seismic energy release and the one of the homogeneous Earth used for the azimuthal intensity vector analysis of the preseismic electric signals (Thanassoulas, 2007).
