Ground motion at 1 Hz detail (counts), high‑pass filtered. Spikes are distant earthquakes; slower swells are regional and cultural noise.

Ground motion power, last 24 hours, 0–2 Hz. Secondary microseism near 0.15 Hz, Lehman boom resonance near 0.08 Hz.

Earth’s magnetic field, last 24 hours (nT). The smooth daily curve is the solar quiet (Sq) variation; storms show as jagged swings. The Kp strip along the top colors each 3‑hour NOAA/SWPC planetary K index bucket: green = quiet, yellow/orange = unsettled to active, red/purple = storm.

Natural electric field in the ground, last 24 hours (mV/km, 135 ft dipole). Shown beneath the magnetometer for coherence comparison; the daily wave is driven by global thunderstorm activity and ionospheric currents.

ELF band from 0–14.5 Hz as detected by the Telluric E‑Field monitor via two buried Terracotta pots.
