| Zusammenfassung |
| In the present work, phenomena in the ionosphere are studied, which are
connected with earthquakes (16 events) having a depth of less than 50 km and a
magnitude M larger than 4. Analysed are night-time Es-spread effects using
data of the vertical sounding station Petropavlovsk-Kamchatsky
(φ=53.0°, λ=158.7°) from May 2004 until August 2004
registered every 15 min. It is found that the maximum distance of the earthquake from the
sounding station, where pre-seismic phenomena are yet observable, depends on
the magnitude of the earthquake. Further it is shown that 1–2 days before the
earthquakes, in the pre-midnight hours, the appearance of Es-spread
increases.
With a probability of more than 0.95, this increase of Es-spread
observations before midnight is not casual. |
