Some science behind the scenes
Fault lines
Fault lines are a major source of change in the earth’s magnetic field. Over the years we have become used to the idea of the major faults lines in the earth’s crust, but there are hundreds of thousands of smaller fault lines over all the world, a great network of criss-crossed lines that generate a change in magnetic field when the faults slip. Thus there is only a change when there is movement, as such any alteration in strength or fluctuation will be very intermittent.

On the left is a map compiled by the British geological survey unit of the fault lines in the UK. As you can see there are hundreds and hundreds, some near the surface and some lower down. |
Puget Sound on the borders of Canada and the USA in the west is, not surprisingly riddled with fault lines because it lies on a major fault line. But, even ignoring this fault line, there are numerous other fracture points.

For example the map here shows the Southern Whidbey Island Fault (SWIF) and the Devils Mountain, Strawberry Point, and Utsalady Point faults (crossing northern Whidbey Island), Seattle Fault zone, southern part of Rattlesnake Mountain Fault Zone, and Tokul Creek Fault (striking NNE from RMFZ).

There is thus the potential, at any time, in numerous places on earth, to experience a change in magnetic field caused by slippage in the fault or movement in the earth’s surface. The movement does not have to be ‘felt’, it can be very minor, but of course its intensity will be very low. Earthquakes produce changes in the magnetic field of much higher intensity.
Where complex fault line patterns are found, with many criss-crossing lines at a centre, or where anomalies in the earth’s crust occur, you can find that there are far more continuous magnetic disturbances.
Dr Michael Persinger has even produced a theory – the ‘1975 Tectonic Strain Theory (TST)’ of how geophysical variables may correlate with sightings of unidentified flying objects (UFOs). Persinger has argued that strain within the earth's crust near seismic faults produces intense magnetic fields. These may create either bodies of light that some interpret as glowing UFOs or the magnetic fields generate hallucinations based on images from popular culture, of alien craft, beings, communications, or creatures. His findings are supported by the work of a number of other people.

Professor Richard Wiseman’s research into haunted houses has indicated that experiences of ghosts, paranormal presences and other strange feelings can be caused by unusual frequencies of electromagnetic levels. Indeed, British ophthalmologist and Fellow of the Royal Society of Medicine, Ann Silk, has investigated the many haunted houses on the Isle of Wight and claims all either lie on or are close to the geological fault line running east–west along the length of the island.
