Earthquakes and Radio propagation
MDSR & RF-Seismograph &
measuring shortwave propagation and possible correlation with
using your own transceiver or receiver!
do Earthquakes create Electromagnetic Fields?
effect of rocks sliding and vibrating on top of each other.
of rocks releasing vast amounts of free electrons.

fields start to emerge out of the earth crust and move upward towards
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.

hole in the Ionosphere?
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!
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.
What is visible on the RF-Seismograph
different stages of the quake as seen by the RF-Seismograph
study for M5.0 event, 256 km SW of Pt. Hardy - N-Vancouver Island,
buildup – noise increases on 80m (red).
of 40, 30 and 20m band – communication dropout.
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.
the energy releases, the ionosphere starts to rebuild slowly and
normal communication continues.
