Schumann Resonance Live

A series of electromagnetic waves formed between the Earth surface and the ionosphere, sustained by continuous global lightning activity. Theoretically predicted by Winfried Otto Schumann in 1952 and measured in the 1960s, its fundamental mode is about 7.83 Hz.

The fundamental frequency remains ~7.83 Hz — a fixed physical property. Natural daily fluctuation is around ±0.1-0.5 Hz. The bright horizontal line in the 7-8 Hz band on the live chart is the first mode.

The color scale represents amplitude (signal strength): dark blue low, green-yellow medium, red-white high activity. The vertical axis shows frequency (Hz), the horizontal axis time (UTC).

Global lightning activity (especially tropical Africa, Asia and America), solar-driven ionosphere changes and day-night transitions continuously vary amplitude. Bright vertical stripes along the chart are usually strong thunderstorm clusters passing the station.

The time axis is UTC. Add +3 in Turkish summer time (UTC+3) and +2 in winter time (UTC+2). The "now" edge is always the rightmost point of the chart.

No. There is no repeatable, verified relationship between Schumann resonance and earthquakes that converts into prediction. Claims linking specific bands to quakes are not supported by the scientific literature.

The Schumann resonance is a natural, extremely weak electromagnetic background. Band amplifications observed in charts have no documented direct health effect; the field strength is many orders of magnitude below everyday artificial sources.

The window is 72 hours; as time advances the right edge may show the not-yet-received region. Station maintenance or data gaps freeze the edges; the freshest frame arrives when the page refreshes.

Our server checks the source spectrogram at most every 10 minutes; the image cache on the page refreshes automatically. The timestamp of the frame is stated in the source caption.
