| Zusammenfassung |
| In this paper we show, in terms of Fisher information and approximate
entropy, that the two strong impulsive kHz electromagnetic (EM) bursts
recorded prior to the Athens earthquake (EQ) (7 September 1999, magnitude
5.9) present compatibility with the radar interferometry data and the seismic
data analysis, which indicates that two fault segments were activated during
Athens EQ. The calculated Fisher information and approximate entropy content
ratios closely follow the radar interferometry result that the main fault
segment was responsible for 80 % of the total energy released, while the
secondary fault segment for the remaining 20 %. This experimental finding,
which appears for the first time in the literature, further enhances the
hypothesis for the seismogenic origin of the analyzed kHz EM bursts. |
