Landers Rupture — Andy on using satellite data

One of the great things is that because it happened out in the desert, the geologists could really observe in detail all of the ground rupture. And, it was the first time we were able to make great use of satellite geodetic measurements, such as InSar, which gives us a very detailed picture of how the ground moved permanently in different places around the Landers earthquake. If it had happened, you know, in an urban area, our scientific observations would have been weaker, but obviously it would have had much more of a societal impact.
