Earth's Heartbeat & Vibration
Visualize the pulse of the planet in real-time through the Schumann Resonance.
Thursday, April 16
The Schumann Resonance measures the electromagnetic frequencies of the Earth's atmospheric cavity, vibrating at a fundamental frequency of 7.83 Hz. Many energy sensitive individuals report feeling heightened anxiety or fatigue during "power spikes" (white patches) on the spectrogram.
First predicted by physicist Winfried Otto Schumann in 1952, these resonances represent the "heartbeat" of our planet's electromagnetic field. Changes in intensity may correlate with global lightning activity, solar events, and geomagnetic disturbances.

What Am I Looking At?
New to Schumann Resonance spectrograms? Follow these three steps to read the display above.
The horizontal axis represents time (UTC). The left edge is the oldest data and the right edge is the most recent. Each spectrogram covers a 24-hour window.
The vertical axis is frequency (Hz). You should see faint horizontal lines at 7.83 Hz, 14.3 Hz, 20.8 Hz and higher harmonics. These are the Schumann Resonance frequencies.
Dark blue/black means low activity. Green and yellow indicate moderate energy. Bright orange, red, or white patches are power spikes — moments of significantly elevated electromagnetic intensity.
Brainwave Correlation
Each Schumann harmonic falls within the range of a human brainwave frequency band. Some researchers have proposed that these planetary rhythms may influence neurological activity, though direct physiological coupling has not been established.
| Schumann Harmonic | Brainwave Band | Range |
|---|---|---|
| 7.83 Hz | Alpha / Theta border | 4–8 Hz / 8–12 Hz |
| 14.3 Hz | Beta | 12–30 Hz |
| 20.8 Hz | Beta (high) | 12–30 Hz |
| 27.3 Hz | Beta / Gamma border | 25–35 Hz |
| 33.8 Hz | Gamma | 30–100 Hz |
Daily Rhythm
Schumann Resonance intensity follows a natural daily cycle driven by global lightning activity. Understanding this rhythm helps you distinguish normal fluctuations from genuinely unusual events.
Activity typically peaks when the African and European lightning centers are most active, roughly 14:00–18:00 UTC.
A second peak often appears around 19:00–22:00 UTC as the American lightning centers intensify.
The quietest period is typically 02:00–08:00 UTC. Bright activity during these hours is more likely to be anomalous.
Tip: If you see a power spike during a normally quiet period, check the Solar Activity page — a geomagnetic storm may be in progress.
Connection to Space Weather
The Schumann Resonance doesn't exist in isolation — it responds to activity far beyond Earth's atmosphere.
Coronal mass ejections and strong solar flares can compress the magnetosphere and alter the ionospheric cavity, potentially causing intensity spikes and frequency shifts in the Schumann bands.
Elevated Kp index values (5+) have been observed to correlate with broadband power increases across Schumann harmonics. During G2+ storms, the spectrogram may appear significantly brighter.
High-speed solar wind streams can disturb the ionosphere over days, producing sustained periods of elevated Schumann activity rather than short spikes.
During solar minimum with low geomagnetic activity, the Schumann Resonance tends to be calmer with cleaner, more defined harmonic bands.
