Radio noise levels before earthquakes

A story in the Fall 1990 WHOLE EARTH REVIEW #68, pp. 101-104, documents a 1984-1987 USGS study which showed a 70% correlation between radio signals on 200 Hz - 100 KHz (signals which BPL, if permitted by the FCC, will largely block).

Multiple citations are included to other research at the end of the article.

I think I will build one, even though when I bought my new home, it was built in Zone Green.
