have discovered in many instances, there are certain electromagnetic frequencies
that propagate very easily through the earth's interior, before, during,
and immediately after, a large seismic movement.
The data shown
on the following pages is a research effort by the Elfrad Group to determine
if there is a feasible method of detecting
these signals before the event, with enough reliability and timing,
to warn of an impending disaster.
a detection method suitable for recovering
these ULF signals, we have found it is sometimes possible to detect
an event up to 120 minutes before the actual occurrence.
This early warning could be very useful in
determining if the seismic anomaly is going to occur in a populated area.
Ultra low and extremely
low electromagnetic transmissions, by their nature, have the ability to
penetrate the earth but have a very huge wavelength making it difficult
to determine the source. It has been found however, that the amplitude
of the signals will vary in proportion to the distance. With many
receive stations placed in strategic locations we are then able to determine
the location and strength.
For instance, our
equipment regularly detects seismic activity and other low frequency anomalies
daily, on a global, rather than a local scale. There are a group of frequencies
which vary in amplitude, in proportion to seismic occurrences around the
world. This spectrum is monitored constantly and when the detection threshold
is exceeded, it is compared with the other Elfrad sites. The receive
site with the higher amplitude would be the closest to the suspected event.
Our detection sites
are staffed by volunteers who have dedicated their equipment, time, effort,
and expense to help in this research effort. Our goal, is to be able to
be an asset in this pioneering field, and to help develop the technology
necessary to prevent tragic loss of life.
