About

Earth Frequency Index is an independent monitoring publication tracking global electromagnetic frequency data. We aggregate readings from monitoring stations worldwide and publish weekly analysis for researchers, wellness practitioners, and the scientifically curious.

Our focus is the Schumann Resonance — the natural electromagnetic frequency of the Earth-ionosphere cavity, with a fundamental mode at approximately 7.83 Hz. First described by physicist Winfried Schumann in 1952, this frequency has been continuously monitored by scientific institutions globally for over seven decades.

Our editorial team reviews all data before publication. Earth Frequency Index does not represent any government, academic, or commercial institution.

What We Monitor

The Schumann Resonance is excited primarily by global lightning activity within the Earth-ionosphere waveguide. Variations in intensity and frequency are influenced by solar activity, ionospheric conditions, and other geophysical factors. We track these variations and publish analysis accessible to both scientific and general audiences.

Our monitoring draws on data from established networks of extremely-low-frequency (ELF) detection stations distributed across multiple continents. We present this data alongside contextual analysis to help readers understand what the readings mean and why they matter.

Editorial Standards

We distinguish clearly between established scientific findings and emerging research. Where the evidence is uncertain, we say so. Our goal is accuracy before accessibility — we will not oversimplify the science to the point of misrepresentation.
