TerraSignal tracks eight geophysical data streams — magnetic field strength, pole drift velocity, abyssal ocean temperature, seismic activity, solar flux, and more — normalized into five scored components. When multiple independent systems deviate simultaneously, the anomaly index rises. No predictions. No interpretations. Just the data.
