1.)How do Earthquakes create Electromagnetic Fields?

• Piezoelectric effect of rocks sliding and vibrating on top of each other.
  
  
• Micro-Fractures of rocks releasing vast amounts of free electrons.
  
  
• Electrons move up towards the surface or sea-floor and circulate around the quake area.
  
  
• Electromagnetic fields start to emerge out of the earth crust and move upward towards the ionosphere.
  
  
• Since the ionosphere contains charged particles, the magnetic field interacts with the ions and creates a hole or a dome of charged particles, affecting radio waves passing through.

2.)A hole in the Ionosphere?

• The magnetic field lines reach into the ionosphere and disturb or bend the layers, breaking existing radio paths. The signals that the Seismograph receives drop out!

•  The equivalent of a magnetic field shooting out of the surface of the sun. Because of the hot plasma, the field lines are visible. This process on the sun is much more energetic than an earthquake here on earth, but the physics are the same.

3.) What is visible on the RF-Seismograph

      The different stages of the quake as seen by the RF-Seismograph

                (case study for M5.0 event, 256 km SW of Pt. Hardy  - N-Vancouver Island, BC)

• Energy buildup – noise increases on 80m (red).
• Disruption of 40, 30 and 20m band – communication dropout.
• Quake releases.
• The energy buildup and blackout continues with most quakes for approx the same time as the before the quake (2 to 8h) for at total of 4 to 16h.
• After the energy releases, the ionosphere starts to rebuild slowly and normal communication continues.
