E. A GPS-based Early Warning System for Earthquakes

Narrator: This is Science Today. The establishment of a real-time network of
GPS tracking stations throughout California , which would serve as an early warning system for earthquakes, is being led by research geodesist Yehuda Bock of the University of California , San Diego 's Scripps Institution of Oceanography.

Bock: We've been involved in an effort to establish these real-time GPS tracking stations throughout California . And those could be used as part of an early warning system, but the real time infrastructure that we're creating, and we have about 100 stations that are now streaming data back to us in real time, the same infrastructure is also being used by people now in local and state government for all kinds of precise applications such as construction, intelligent transportation, landslide monitoring, bridge monitoring. So, we're developing a real-time infrastructure based on GPS technology.
