The seismic streaming page at EPD Laboratories just got a serious upgrade. Go check it out — it doesn’t look like anything else on the internet.
The EPD-SM1 Seismic Stream Monitor is a custom-built audio player styled after vintage broadcast equipment — complete with a live VU meter showing signal level in real time, and a full signal chain display showing the path from the antenna field through cellular uplink to the Icecast server to your monitor. Hit play and you’re listening to the electrical signals between the ionosphere and the interior of the earth, picked up by an above ground Beverage Antenna at EPD Laboratories in Tonopah, Nevada — 4,800 ft above sea level. Try out the volume slider — it’s fully interactive.
Below it sits the EPD-CR1 Earth Signals Chart Recorder — a real-time scrolling waveform display with adjustable gain (1x, 3x, 5x, 7x). This is a mock recorder for now to show the effect — we’ll be getting into logging the earth signal data and analyzing it with AI and other tools. Coming soon. Play with the gain button and experiment.
There’s also a working spectrum analyzer on the page. You can see the frequencies coming through in real time — the active frequency shows in yellow and the green trace is an RMS average over 60 seconds. Look around the 12-14 kHz range and you’ll notice consistent signals being picked up. Those are the Russian Alpha Navigation System (RSDN-20) broadcasts — a long-range military navigation network operating at approximately 11.905 kHz, 12.649 kHz, and 14.881 kHz.
The pops and clicks are lightning strikes. When those strikes produce pitches — chirps and squeaks — those are responses to lightning creating standing wave situations in the earth. More options are coming — some free and some by subscription.
Special thanks to Hakasays (who will be presenting at ESTC 2026) for streaming the earth signals live. One of his many contributions is that he pays for the cellular data plan to stream it from the shack in Tonopah to the internet. Thank you. And special thanks to Simon Davies of teslascientific.com for help in making the system look better and making the spectrum analyzer more useful.
