Zusammenfassung |
Here, we check the obedience of new data, derived from the Mw =
5.4 earthquake on 7 August 2013 in Central Greece, to a previously found
power law relation by the author between the stress drop of an earthquake and
the lead time of its precursory seismic electric signal (SES). An exponent
value α =0.329 has been found which is in excellent agreement with
previous ones reported in a series of articles by the author. This value
falls in the range of critical exponents suggested by various models for
fracture and is very close to a reported one which interconnects the
amplitude of the SES and the magnitude of the impending earthquake. The
stability of this exponent confirms the credibility of the above-mentioned
power law and probably implies that real physical dynamic processes evolving
to criticality are present in the pre-focal area when the SES is emitted. |
