Our Science

This work led to the discovery of peroxy defects. After some 40 years of research 

combining solid-state and semiconductor physics, material science, electrochemistry and various forms of spectroscopy 

Friedemann Freund and his scientific team succeeded characterizing these peroxy defects and their properties.


By the late 1990 s and early 2000s, it became clear that most rocks, especially those deeper into the Earth’s crust, contain minerals that are laced with peroxy defects and stress is able to activate these peroxy defects, causing highly mobile electronic charge carriers to be released, including “positive holes”, which produce an array of secondary and tertiary reactions inside the Earth crust, at the Earth surface, in bodies of water, in the atmosphere all the way up to the ionosphere.

Diagram A contains on the left the boxes in the oval red circle. We do not plan to study those except that Gerassimos Papadopoulos may be interested in recording the microseismicity as part of this supportive analysis of seismological records.

Diagram A contains on the right parameters pertaining to changes in the water. We plan to deploy cation/anion sensors and fluorescence sensors in all stations that have access to ground or well water.

1)        Ionospheric anomalies are typically detectable days to weeks before major seismic events. They express themselves as increases in the Total Electron Content (TEC), best recorded at night when the effects of the solar radiation on the ionosphere are less than during the day. TEC anomalies can be recorded by (i) GPS technology to reconstruct tomographic images of the ionosphere over seismically active regions; (ii) “over-the-horizon” FM radio wave transmission to detect changes in the morning or evening terminator times; and (iii) long-distance AM radio waves reflected off the ionosphere over the seismically active region.

(2)        Thermal Infrared (TIR) anomalies express themselves as (i) radiative temperature increase of the Earth surface and (ii) radiative temperature increase at the top of the clouds, also known as Long Wavelength Infrared anomalies. TIR anomalies mark the epicentral region and become detectable days to weeks before major earthquakes. They can be detected by satellite-borne infrared imagers.  Medium resolution images can be obtained from MODIS on the NASA satellites TERRA and AQUA, each providing one data point during the day and one during the night per each 24-hour period. Detection is also possible using geostationary weather satellite images, every 15-30 min, to record night time cooling curves .
(3)        Anomalous CO release from the ground is currently retrievable from the MOPPIT sensor on board the NASA TERRA satellite providing daily global data

Diagram B contains the green boxes. We expect to place ground potential sensors and tree potential sensors at all stations in rural areas.

Diagram B contains the light blue boxes. Stations with soil conductivity sensors will be placed at stations, maybe 20 out of 120, where we can install the necessary ground electrodes in a similar manner like the Chinese have been doing it for decades.  The trace gas sniffers for CO emission are to be combined with the ozone sniffers and air ionization sensors shown on Diagram C. As to the radon emission, we’ll wait until we hear to what extent we may be able to revitalize the network of radon sensing stations originally set up by Sedat Inan. Don’t pay attention to the last box with CO2, H2, He which require mostly lab analysis.

(4)        Increase in positive and negative air ion concentrations using networks of ground stations to measure air ionization, typically 100-200 km apart.

(5)        Changes in the total magnetic field intensity, x, y, z-components to be measured by ground stations typically less than 100 km apart.

(6)        Emission of ultralow frequency (ULF) electromagnetic (EM) waves from the ground. Both of these unipolar pulses typically last between 100 msec and 1-2 sec. Continuous ULF wave trains last minutes to hours, and their x, y, z-components can be measured by ground stations preferentially about 50 km apart.

(7)        Regional changes in radio frequency noise at different frequencies from very low to medium low (VLF-LF).

(8)        Soil resistivity changes can be detected 1-2 m deep as measured by 4-point ground electrode systems, typically less than 100 km apart.

(9)        Radon emanation from the soil by stations, typically less than 100 km apart.


(10)      Changes in water chemistry at commercial n natural spring water bottling companies or from ground water wells, typically 1-2 for every watershed.

Diagram C contains most boxes, but only a few refer to local ground station needs.


The most important is the blue box for positive (and negative) air ionization, which we plan to measure at as many stations as possible. Linked to air ionization are the orange boxes for corona discharges which lead to ozone formation, TV signal perturbations and more. Ozone sniffers with be co-located with CO sniffers on Diagram B. Corona discharges lead to broad-band radio noise and, hence, TV signal perturbations.  To detect those it will be enough to equip maybe 20 sensors out of 120 total network.

The yellow box for the Thermal Infrared Emission and all purple boxes refer to information to be retrieved from satellite data – except for the Chromatic Shifts, for which it will be enough to deploy a camera with fish-eye lens and sensitivity into the near-infrared at one or two locations.  


All other satellite information can be monitored at any location in California, Switzerland, Turkey or anywhere else around the globe.

  The following list describes the cascading effects of how the signals are generated:

  • 1. All igneous and high-grade metamorphic rocks contain electrically inactive, dormant peroxy defects in the matrix of their constituent minerals.

  • 2. When rocks are stressed, peroxy defects become activated, generating electrons and defect electrons, the latter known as positive holes.

  • 3. Positive holes flow out of the stressed rock volume, spreading along stress gradients into and through the surrounding less stressed or unstressed rocks.

  • 4. Positive holes propagate at initial speeds on the order of 100 m/s over distances of kilometres to tens of kilometres, probably even hundreds of kilometres.

  • 5. As positive holes flow, they form electric currents generating magnetic fields.

  • 6. If positive hole currents fluctuate, they generate electromagnetic (EM) waves, of which those in the ultralow frequency range can travel through the rock column.

  • 7. ULF waves may occur in the form of single bursts, so-called unipolar pulses, or of wave trains that can last a few minutes to hours, sometimes days or even weeks.

  • 8. When positive holes arrive at the ground-water interface, they oxidize H2O to H2O2, affecting groundwater chemistry.

  • 9. When positive holes travel through the soil on their way to the surface, they oxidize organic matter generating CO and aid in the release of radon.

  • 10. The positive holes also affect the electric field distribution across the ground-air interface, which can be assessed by tree potentials and ground potential sensors.

  • 11. When positive holes arrive at the Earth’s surface, they will seek out topographic highs and accumulate at the ground-air interface.

  • 12. At the ground-air interface positive holes recombine to return to the peroxy state.

  • 13. Because the recombination is exothermal, excess energy is radiated off as IR photons, a process causally linked to the Thermal Infrared (TIR) anomalies.

  • 14. When more positive holes arrive at the ground-air interface, electric (E) fields at the surface begin to field-ionize air molecules, producing positive airborne ions.

  • 15. Positive airborne ions have a pronounced physiological effect and are implicated in pre-earthquake changes in animal behavior.

  • 16. The air bubbles laden with positive airborne ions, rise to stratospheric heights.

  • 17. The rising positive air ions polarize the ionospheric plasma, causing electrons to be pulled downward, causing measurable Total Electron Content (TEC) anomalies.

  • 18. As the positive air ions continue to rise through the mesosphere, they organize into columnar cells, which arrive at the ionosphere at vertical speeds of 20-30 m/s, confirmed by Doppler broadening.

  • 19. The cells of the rising ions cause a "bumpiness" of the E-field as recorded by satellites from above and by Very Low Frequency (VLF) radio scatter from below.

  • 20. At the ground-air interface, increasing numbers of positive holes arriving from below cause corona discharges, leading to broad-band radio noise (in the 500 MHz range), the instant formation of ozone and of negative airborne ions.

Depiction of the basic process, the build-­‐up of tectonic stresses (thrust, strike-­‐slip, normal), Which causes rock deformation and thereby activates electrons and positive holes. Flowing out of the stressed rock volume, the positive holes lead to a positive charge at the Earth’s surface, which in turn lead to follow-­‐on reactions that have consequence throughout the atmospheric column up to the ionosphere.
