Los Angeles - Understanding earthquakes is difficult even for the most dedicated. You not only need to wait for a quake to happen, but the quake needs to be in the magnitude 5-6 range.

The 8.8 Chilean tremor offered scientists their first whack at seeing how fast new satellite and GPS detection can work in a major quake. Jeff Michael has more in this video report.
