What is this?

The Schumann Resonances are natural electromagnetic waves trapped between Earth's surface and the ionosphere. They are mainly generated by global lightning activity and resonate at:

Fundamental: 7.83 Hz
Harmonics: ~14, 20, 26, 33 Hz

This viewer displays the live spectrogram from the SOS70 Observatory (Tomsk, Russia), updated every few minutes.

What is this used for?

Schumann Resonance monitoring is used by researchers, hobbyists, and atmospheric watchers to observe changes in Earth's electromagnetic environment. These signals can reflect:

Global lightning activity
Changes in the ionosphere
Solar activity effects
Geomagnetic disturbances
Atmospheric electrical conditions

While not a direct “earthquake predictor,” Schumann data is often watched alongside space weather, geomagnetic indices, and atmospheric sensors for broader situational awareness.
