I like this idea of distributing the load, but what about a phone app that was able to use the sensors on your phone. I would think there would be some way of using the iPhone's internal sensors for this purpose, and pushed via an app store, I think it would reach more people. IDK...

The sensors in your phone are totally unreliable to seismic detection. In addition to that the detector should be still.
The challenging part is once the algorithm has detected potential earthquake, how would you distribute the alert within few seconds to everyone? My guess is this should be done on GSM/UMTS network level, rather that using mobile app and relying on no-latency transport.
