A Cheap, Ubiquitous Earthquake Warning System

While a cool hack, its more practical to simply combine data sensing networks for detection. Take a look at how massive the CORS GPS reference network is: http://www.ngs.noaa.gov/CORS_Map/

The CORS GPS network is used for precise positioning using position averaging and correction for any atmospheric interference.

Armchair engineering, I would assume the cost for a solid state seismometer (3 axis accelerometer) would be trivial enough to add onto existing reference stations to provide precise positioning data, as well as comprehensive movement data.

The Comprehensive Nuclear-Test-Ban Treaty is monitored by a global network of seismic, infrasound, hydroacoustic and radionuclide sensors. www.ctbto.org/map/

These usually end up detecting earthquakes though http://www.ga.gov.au/scientific-topics/hazards/nuclear-monit...
