via the ARRL: VE7DXW’s “RF Seismograph” May Be Real Seismograph

Alex Schwarz, VE7DXW, in British Columbia, Canada, is exploring the possibility that “RF signatures” detected by the RF Seismograph propagation tool could also be indicating earthquakes, and may even be able to predict them shortly before they occur. A real-time HF propagation-monitoring tool developed by Schwarz and the MDSR team, the RF Seismograph shows both band noise and activity or band activity alone on six HF bands. It’s a project of the North Shore Amateur Radio Club (NSARC).

“We had been doing the solar eclipse experiment, and we developed the RF Seismograph software to look for changes in propagation during the eclipse,” Schwarz explained. “After the eclipse, we decided to leave the RF Seismograph running, and we have now collected 4 years of data.”
