We 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.
By developing 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.
