Schumann resonances

Live data from CUMIANA (TO), NW Italy, south Europe

VLF monitoring

Here below the first LIVE spectrogram, updated 30 minutes.
It shows the last 8 hours VLF activity, as received by Marconi antenna (vertical electric field).

Marconi Antenna + Geophone

Amplitude scale: two channels listed below.

  • Channel 1, seismic monitor. Frequency range: 1 to 30 Hz for the top spectrogram. Signals coming from geophone I/O SENSOR Nederland b.v. model SM-4/UB8 (see at SM-4_Brochure.pdf) 40 dB amplified with a very low noise preamplifier.
  • Channel 2, electric field. Frequency range: 1 to 105 Hz for the bottom one. Signals coming from Marconi antenna, with a low noise current preamplifier, placed at the bottom of it  (LNVA_20-24).

Picture, every 30 minutes, shows last 8 hours. All date and times are in UTC.
The scroll time is 40 s, and FFT frequency resolution 21 mHz.
As the receiving station is placed not too far from an industrial area, sometimes strong tones are detected by geophone sensor, caused by mechanical machine (1 km far from here).

Electric filed multistrip daily representation, useful for comparing anomalies from day to day:

Scroll time 110 sec, updated every 30 minutes, FFT frequency resolution 10.5 mHz.

Geophone Multistrip hourly representation, useful for local seismic events correlation:

Scroll time 4.6 sec, updated every 60 minutes, FFT frequency resolution 112 mHz

Here below the same data elaborated as plotting traces. The picture shows the last 30 hours, and values are detected every 150 s.

Picture, updated every 30 minutes. Four traces are reported:

  • Geophone trace , it shows the average and peak signals coming from the geophone sensor, in 1-20 Hz range.
  • ULF noise 10 Hz , it shows the medium value between 3 and 30 Hz.
  • ELF noise 100 Hz , it shows the medium value between 30 and 300 Hz.
  • 2th SR freq. , it shows the frequency of second Schumann resonance (in Hz).

What Are The Schumann Resonances?

The Schumann resonances (SR) are a set of spectrum peaks in the extremely low frequency (ELF) portion of the Earth’s electromagnetic field spectrum. Schumann resonances are global electromagnetic resonances, generated and excited by lightning discharges in the Earth’s electromagnetic cavity (The space between the Earth’s surface and the Ionosphere). The resonant frequencies are between 3-60 Hz and have distinct peaks around the following extemely low frequencies;

  • 7.83 Hz (fundamental)
  • 14.3 Hz
  • 20.8 Hz
  • 27.3 Hz
  • 33.8 Hz

Kennely and Heaviside first suggested than an ionosphere capable of trapping electromagnetic waves existed in 1902. 20 years later Edward Appleton and Barnett were able to prove the existence of the ionosphere.

Nikola Tesla

Tesla researched ways to transmit power and energy wirelessly over long distances (via transverse waves, to a lesser extent, and, more readily, longitudinal waves). He transmitted extremely low frequencies through the ground as well as between the Earth’s surface and the Kennelly-Heaviside layer. He received patents on wireless transceivers that developed standing waves by this method. In his experiments, he made mathematical calculations and computations based on his experiments and discovered that the resonant frequency of the Earth was approximately 8 hertz (Hz). In the 1950s, researchers confirmed that the resonant frequency of the Earth’s ionospheric cavity was in this range (later named the Schumann resonance).

“So astounding are the facts in this connection, that it would seem as though the Creator, himself had electrically designed this planet….” – Nikola Tesla describing the Schumann Resonance in “The Transmission of Electrical Energy Without Wires As A Means Of Furthering World Peace” Electrical World And Engineer, January 7, 1905, PP 21-24.

Winfried Otto Schumann

Winfried Otto Schumann who first studied the theoretical aspects of the global resonances of the earth–ionosphere waveguide system, known today as the Schumann resonances. In 1952–1954 Schumann, together with H. L. König, attempted to measure the resonant frequencies. However, it was not until measurements made by Balser and Wagner in 1960–1963 that adequate analysis techniques were available to extract the resonance information from the background noise. Since then there has been an increasing interest in Schumann resonances in a wide variety of fields.

How Does This Affect Me?

Effects on Humans

The Schumann Resonance signal provides a brain frequency range matching electromagnetic signal, providing the synchronization needed for intelligence

It’s been shown that Schumann Resonance is an important aspect in the modulation of human health and assists the sun and maintaing the circadian ryhthm

The diurnal cycle of the SR signal alters serotinin/melatonin which in turn affects canncer cells, cardiovascular health, neurlogical processes, and reproductive systems

It is interesting to note the close match between Schumann Resonance frequencies and the electrical activity recorded by an electroencephalograph (EEG) on the human brain.

Frequency range of the brain coincides with the SR signal (0-45hz)

Human brain waves have the following frequencies:

StateFrequency rangeState of mind
Delta0.5Hz–4HzDeep sleep
Theta4Hz–8HzDrowsiness (also first stage of sleep)
Alpha8Hz–14HzRelaxed but alert
Beta14Hz–30HzHighly alert and focused

The brain uses an ELF oscillating system, primarily making use of calclium-ions to control neurotransmitters

External ELF signals induce altered neuron calcium ion effluxes in brain tissue.

Animals and humans have evoleved in an environment saturated by the SR signal for roughly 3 billion years.

Stable synchronization of the brain by SR signals has led to thinking, emotion, memory, and intelligence

Environmental Effects

S/GMA (Solar/Geomagnetic Activity) has been shown to affect the SR signal amplitude (strength), and as we know the schumann resonance cycle effects human beings.

Correlations between sunpspot number and GMA activitity indices also coincide with certain health effects.

X-ray and gamma radiation rom solar winds have an impact on the SR signal strength and can alter the diurnal cycle. X-rays ionize the atoms it comes in contant with and enhances concentration of ions in the D-region of the ionosphere. Di-region is the top of the ionosphere cavity in which the SR signal exists.

Daily variation in the D-region produces the variation in the SR signal. Solar storms are also known to produce variations in the SR signal.
