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. Presumably there is some change due to the solar sunspot cycle as the Earth's ionosphere changes in response to the 11-year cycle of solar activity. Schumann resonances are most easily seen between 2000 and 2200 UT.

Given that the earth's atmosphere carries a charge, a current and a voltage, it is not surprising to find such electromagnetic waves. The resonant properties of this terrestrial cavity were first predicted by the German physicist W. O. Schumann between 1952 and 1957, and first detected by Schumann and Konig in 1954. The first spectral representation of this phenomenon was prepared by Balser and Wagner in 1960. Much of the research in the last 20 years has been conducted by the Department of the Navy who investigate Extremely Low Frequency communication with submarines.
Schumann Resonance?



Geophysical Condition #1: Earth's Rising Base Frequency


Earth's background base frequency, or "heartbeat," (called Schumann resonance, or SR) is rising dramatically. Though it varies among geographical regions, for decades the overall measurement was 7.8 cycles per second. This was once thought to be a constant; global military communications developed on this frequency. Recent reports set the rate at over 11 cycles, and climbing. Science doesn't know why, or what to make of it. Gregg Braden found data collected by Norwegian and Russian researchers on this; it's not widely reported in the U.S. (The only reference to SR to be found in the Seattle Library reference section, is tied to the weather. Science acknowledges SR as a sensitive indicator of temperature variations and worldwide weather conditions. Braden believes the fluctuating SR may be a factor in the severe storms, floods, and weather of recent years.)

Geophysical Condition #2: Earth's Diminishing Magnetic Field


While earth's "pulse" rate is rising, her magnetic field strength, on the other hand, is declining. According to Professor Bannerjee of the University of New Mexico, the field has lost up to half its intensity in the last 4,000 years. And because a forerunner of magnetic polar reversals is this field strength, Prof. Bannerjee believes that another reversal is due. Braden believes that because these cyclical Shifts are associated with reversals, Earth's geological record indicating magnetic reversals also marks previous Shifts in history. And, within the enormous time scale represented, there were quite a few of them.
