The earth’s crust is in continuous motion due to seismic and tectonic forces. This movement generates discontinuities or fractures in the subsurface rocks. Among these discontinuities, the most problematic are faults and diaclases, popularly known as geopathic stress because of their effects on health.


Faults are the scars of break movements between two blocks. Diaclases are fractures in rocks that lack any visible or measurable movement parallel to the surface.

There are different types of fissures depending on how the two blocks move between them: downward, lateral or rotating. However, our interest in terms of health effects focuses on whether groundwater flows through these scars, taking advantage of the lower resistance offered by the fractures. According to this criterion, faults can be:

  • Wet faults, if water flows through its interior.
  • Dry faults, no watercourse, and more critical to health.

In nature, they can usually be detected by observing the landscape. On the other hand, in the civilized environment they are always covered and hidden from human sight.


Faults or fissures are openings through which there is a lower resistance of the ground to the escape of radiation and gases, specifically:

  • Radon gas finds an easier escape route to the outside and houses built on top of fissures tend to accumulate higher doses of this carcinogenic gas.
  • Natural radioactivity, such as the gamma rays, also finds an easier escape to the outside, increasing the cellular stress of the people above them.
  • The Earth’s magnetic field increases just above the vertical of fissures.


Among the most common effects on people living above faults are the following:

  • insomnia
  • Affections to the circulatory system
  • nervousness
  • irritability
  • hyperactivity
  • emotional hypersensitivity

It is precisely at night, when the body rests, that higher levels of radiation are measured in the vertical of faults and diaclases. For this reason, it is important not to place the bed on the vertical of a fissure.


Under house faults may be suspected if vertical cracks are observed in the building. You may also suspect their presence under the bedroom if you sleep better in another room.

They can be detected by means of technical devices that measure increases in the earth’s natural radioactivity and the earth’s magnetic field, or by means of dowsing instruments, such as pendulum or “Y” rods.

Geobiology studies the effects of this natural energy from the Earth on human health. A geobiological study measures all the natural and artificial radiation at home and proposes actions to live in a healthier space.

Usually, the simplest solutions are the most effective, and simply moving the bed away from the vertical fault line can greatly improve sleep.
