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

TL;DR

This study analyzes seismic activity in the Methoni area, Greece, from February to April 2008, correlating it with Earth's electric field data and lithospheric oscillations to validate physical models of earthquake precursors.

Contribution

It integrates seismic, electric field, and lithospheric oscillation data to validate models predicting earthquake timing and location in the Methoni region.

Findings

Seismic activity correlates with lithospheric oscillations and electric field signals.

The models used successfully predicted the seismic event timing and location.

Seismic energy release aligns with the probabilistic seismic event analysis.

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).
