Hi Charlie, Most interesting, I also, would be interested to see the data
prior to the event. Anyhow, this may be of interest to you, I'm putting
together a fluxgate magnetometer , and the supplier of the fluxgate
devices sent me this article.

Long-term ELF background noise measurements, the existence
of window regions, and applications to earthquake precursor
emission studies.

You probably aware of the article, but,  if you or a PSN reader is unable
to obtain a copy through your library then email me and I'll "PDF" the
document or fax it to you.

I'm taking a stand alone digital approach to recording the earths magnetic field

but with the aid of a simple circuit (F/V converter) you can record the magnetic

field as analogue signal. Maybe another channel on SDR or EMON.
