Initially Problems in Observing 0S0

Authors: Herbert Weidner
Comments: 5 Pages.

Superconducting gravimeters are overloaded by strong earthquakes and stop the measurement. Here it is shown that, in the first hours after restart, most of the SG deliver erroneous data, which prevents an accurate frequency measure­ment. Avoiding this disturbed region, the frequency can be determined much more accurately than before.

A Detailed Analysis of the 0S0 Resonance of the Earth

Authors: Herbert Weidner
Comments: 10 Pages.

Long-term spectrograms show that after strong earthquakes, the frequency of the 0S0 resonance of the earth varies with no apparent regularity. This also applies to the structure and the location of the side­bands. Measurements with the zero beat method show a frequency modulation of unknown cause, which can hardly be detected by FFT.

On the Antipodal Symmetry and Seismic Activity.

Authors: M. Kovalyov, N. Kovalyov, S. Kovalyov.
Comments: 8 Pages.

The article discusses the global aspects of the (almost) antipodal symmetry on Earth which should have been widely known by now but somehow managed to stay unnoticed.
