IGPP's Yehuda Bock, director of California Spatial Reference Center, spoke to San Diego's Channel 10 News about the addition of "small, inexpensive seismic and meteorological sensors" to exisitng GPS sensors in San Diego and surrounding Southern California counties. The sensors, which transmit data in real-time, can detect initial seismic waves.
"Based on that information, we can very quickly, within seconds, determine what the magnitude of the earthquake is going to be," said Bock.
These sensors will give the public and local safety agencies 30 seconds to two minutes warning time. For more information, click here.
