Telluric is a read-only observatory. It does not forecast earthquakes, eruptions, or geomagnetic storms beyond what NOAA already publishes.

110 m land polygons for the seismic map
Seismic energy uses the Kanamori relation E = 10^(1.5 Mw + 4.8) joules. Aurora ovals on the map are a Feldstein-style latitude of 75.5° − 2.4 Kp, drawn as a simple parallel — good enough to show how a storm pulls the oval equatorward, not a precipitation model.
The Schumann waterfall is a cavity model peaked at the first five observed modes. It is labeled as a model because it is one.
