Live Earth Monitor: Schumann Resonance
Schumann resonance spectrograms track extremely-low-frequency electromagnetic activity in the Earth-ionosphere cavity. This feed is observational context only; local weather, instrumentation, and station noise can affect the display.
How to read it
Bright horizontal bands near the low-frequency resonance modes indicate stronger ELF signal energy. Sudden vertical flashes can be transient disturbances, lightning-driven bursts, instrument noise, or broader electromagnetic activity. Use it as a companion monitor next to seismic and geomagnetic data, not as a standalone hazard signal.

| 🌋 | Volcano (Static Location) |
| 💧 | Flood (NASA EONET active/recent events) |
| ☀ | Drought (NASA EONET current events if available) |
| 🌀 | Active Tropical Cyclone / Tropical Storm (NASA EONET open events) |
| 🔥 | Wildfire (NASA EONET events updated within 7 days) |
Live earthquake data can be loaded from USGS, EMSC, GFZ/GEOFON, or a combined deduplicated multi-agency option. ISC is not listed because its event service does not allow browser-side CORS fetches. Wildfire overlays use NASA EONET events updated within the last 7 days. Floods use active/recent EONET flood records because open flood events are not always exposed by the live endpoint. Drought appears only when EONET has current drought events available; when NASA has no current drought records, the overlay will report that clearly. Tropical events are filtered to hurricane, cyclone, typhoon, and tropical-storm style systems.
Important note: Volcano overlay is static and does not update in real-time. See Volcano Discovery live image on the Volcano Monitoring page for currently active volcanoes. Volcano map overlay is meant for reference only.
