  1. Recorded Aseismic Signals Mohamed ElGabry National Research Instutite of Astronomy and Geophysics Helwan, Egypt International Center for Theorticalhysics Trieste, Italy

  2. Spectrogram and spectrum of Cross correlation function between two Stations (AYT, FYM) It is clear that there is interference at about 1 HZ

  3. Time Series recorded from A) HRD24, B) Trident Arrows show a transit signal repeated every one second in HRD24

  4. A B Power Spectrum for the Time Series recorded from A) HRD24, B) Trident Arrow shows rapid changes in the spectrum curve of HRD24 at 1 Hz second in HRD24

  5. Time Series recorded from A) HRD24, B) Trident Arrows show a transit signal repeated every one second in HRD24
