1.  If you are active in Parallax propeller development, check out the Forums on parallax web site for the Discussion entitled "ADC Sampling Breakthrough" which is a part of the P2 development forums. in order that you may get some ideas with respect to what is involved in bringing up an entire DSP library from scratch., including ADC design, Verilog, etc. This is not for the faint of heart - and yet Parallax has been great, and most people, if they only knew - would probably say that they have the best tech support of any company, especially in that many of the features that are going into the forthcoming P2 are for all intents in purposes …. feature requests from the Hacktivist community, for things like HDMI, USB, high speed DSP, etc.

2.  If you are not convinced how signals from an deep pressurized aquifer can detect seismic signals, grab a Diet Coke from the fridge, shake it vigorously, but do not open the can - or you will get your own Geyser!  Now hold the bottom of the can up to your ear, and listen to the bubbles forming and be reabsorbed inside the can.  Interestingly enough, it is not necessary to open the can to "get some sounds", it just simply works that way.  Of course, with a few million acre feet of high pressure sub-terraranan carbon dioxide steam, what should be happening is that when CO2 bubbles form in response to weak P-wave interactions, the bubbles that form will begin to rise, and when they rise they will expand, so that the production of said bubbles will be irreversible, at least for the CO2 that reaches the surface.  Thus just like a sigma delta ADC, all we need to do is count the bubbles, so to speak - and thereby recover a replica of the original P-wave modulation.  Fortunately, for us - the USGS does this part for us!

3.  Viewing the spectrograms from Geyser Peak, among others, it is immediately obvious that prior to the July 4 and 5 earthquakes there was more a less a kind of "WOW" signal, for those that are familiar with that "other wow signal.", i.e., if yo know about that one.  One way to try to extract data from the spectrograms therefore is to just simply look at them and guess about what it might mean, or else we can try to turn the .png files that are available from USGS back into bitmaps, and then run some more additional analysis, other than what the government is already doing, such as looking at the signals as if we were trying to build a pitch to midi convertor for a Theremin or something similar.  

4.  If it continues to work into the future, i.e. whenever there is the right build up of oscillations with an increasing amount of phase noise, etc., with an increase in frequency followed by a decrease in frequency of associated sympathetic oscillations indicating something like a material yielding curve for a system undergoing visco-elastic failure, then the rate of change of frequency on the f-downslope can be used to compute-estimate-forecast-predict the near exact TIME of a major seismic event, hours or perhaps even days in advance.

5.  And if it doesn't work in general, elsewhere, when the method is applied correctly?  Well, hopefully I am going to be able to build some really interesting Euro-rack synth stuff for further adventures in dub-step, electro-punk, EDM, etc.
