Re: Towards a Unified Theory for Pre-Earthquake Signals, Friedemann Freund, NASA Ames

thanks, Emily, for the fascinating PP. Finally - an apparently reliable forecasting tool. Does the IR effect occur for every earthquake?

I didn't go back and check each quake mentioned, but I wonder if they're all surface horizontal movements and how many are plates sliding at great depths.

The one Alaska quake (6.7 Nenana Mts. 2002) has IR effect showing in the same general area as that effected by the HAARP antena array near Gakona - designed to disturb the ionisphere. Interesting coincidence, eh?

Do you know if there were IR photos taken prior to the Indonesian earthquake that generated the current volcanic eruption?

I'm glad you're interested in this, AD. The ionosphere research looks hopeful, but you are way ahead of me as far as your questions indicate. I noticed that Friedemann Freund has a page at NASA and seems to encourage questions. And I noticed that NOAA is into this and invites questions here:

You might be interested in this article, too.

It says that the 1964 Alaska earthquake is what got research into relationships between the ionosphere and seismic events going. I saw a comment, (anonymous unverified, though), about people near Homer seeing strange lights in late September, and this article describes what sounds like EQL's seen in the area in 2007.

So some of the ionosphere research might be fruitful for Alaskan predictions. USGS scientists are becoming interested in the field, too.

And here is the article in the Journal of Zoology by Dr. Grant on the unusual toad behavior prior to the L'Aquila earthquake. It ties into all this.
