A Schumann Resonance

What is a Schumann Resonance?
Believe it or not, the Earth behaves like an enormous electric circuit. The atmosphere is actually a weak conductor and if there were no sources of charge, its existing electric charge would diffuse away in about 10 minutes. There is a ‘cavity ‘defined by the surface of the Earth and the inner edge of the ionosphere 55 kilometers up. At any moment, the total charge residing in this cavity is 500,000 Coulombs. There is a vertical current flow between the ground and the ionosphere of 1 – 3 x 10^-12 Amperes per square meter. The resistance of the atmosphere is 200 Ohms. The voltage potential is 200,000 Volts. There are about 1000 lightning storms at any given moment worldwide. Each produces 0.5 to 1 Ampere and these collectively account for the measured current flow in the Earth’s ‘electromagnetic’ cavity.
The Schumann Resonances are quasi standing wave electromagnetic waves that exist in this cavity. Like waves on a spring, they are not present all the time, but have to be ‘excited’ to be observed. They are not caused by anything internal to the Earth, its crust or its core. They seem to be related to electrical activity in the atmosphere, particularly during times of intense lightning activity. They occur at several frequencies between 6 and 50 cycles per second; specifically 7.8, 14, 20, 26, 33, 39 and 45 Hertz, with a daily variation of about +/- 0.5 Hertz. So long as the properties of Earth’s electromagnetic cavity remains about the same, these frequencies remain the same.
For many years this resonance frequency has hovered at a steady 7.83 Hz with only slight variations. In June 2014 that apparently changed. Monitors at the Russian Space Observing System showed a sudden spike in activity to around 8.5 Hz. Since then, they have recorded days where the Schumann accelerated as fast as 16.5 Hz.
These emerging resonances are naturally correlated to human brainwave activity. A 7.83 Hz frequency is an alpha/theta state. 

Relaxed, yet dreamy—sort of a neutral idling state waiting for something to happen. A 8.5 – 16.5 Hz frequency moves one out of the theta range into more of a full calmer alpha state with faster more alert beta frequencies starting to appear.
