Association of the negative anomalies of the quasistatic electric field in atmosphere with Kamchatka seismicity
One hundred three cases of a bay-like depression in the strength of the <I>Ez</I> component of the quasistatic electric field in the near-Earth atmosphere, observed from 1997 to 2002 on Kamchatka, have been analyzed statistically. It has been shown that the most probable...

| Summary: | One hundred three cases of a bay-like depression in the strength of the <I>Ez</I> component of the quasistatic electric field in the near-Earth atmosphere, observed from 1997 to 2002 on Kamchatka, have been analyzed statistically. It has been shown that the most probable length of a bay is 40–60 min. The most probable drops in <I>Ez</I> are minus 106–300 V/m. The dependence of these values on an earthquake class and a distance to the epicenter was not found. The probability of earthquake prediction over 24 h before an earthquake based on the <I>Ez</I> anomaly is 36%. |
