Interesting. In the US coverage of the Haiti disaster it was mentioned that there is a 99.7% chance of the San Andreas fault in Southern California producing an Earthquake of magnitude 6.7 or greater within the next 30 years. This would do substantial damage to several US cities, including to some extent or another the major coastal ones like San Fransisco and LA. If this research allowed the timing of the quake to be determined with adequate enough precision to prompt an evacuation we would so to speak be in your debt.

All you need to do is listen to the song of the planet and of course accurately map out the planets substrata. A stresses alter the loads on fault structures, so the sounds travelling through those fault structures is altered (not sound generated at the fault). Deeply buried microphones measuring and comparing background noise and it's fluctuation, together with a map detailing types of material with estimated load failure points. A whole lot of microphones over a large area with computer driven cross comparison statistical analysis. The more quakes in the area the more accurate it will become.
