But there are apparently some theories that large seismic events *may* actually cause disturbances in the geo-magnetic spectrun, and thus may be detectable by radio-astronomers, though in a much much lower frequency spectrum. From the limited amount I understand, most of the "evidence" for the above is anecdotal at best, but there are various groups looking in to the possibility of being able to record such disturbances, with the possibility being that *maybe* such disturbances would also precede the actual earthquake event and thus give us some kind of warning.
Again, I'm a real n00b in this new hobby, but I'm looking forward to attending the
S.A.R.A conference in Green Bank, WV this summer, so hopefully I'll have gotten a bit more educated by then. This is really nifty stuff!
