Thus, a satellite system may be able to predict volcanic eruptions.

A lot can depend on completely unobvious things.

Satellites can measure topography very accurately and they are frequently used. Many new sites have been discovered in Egypt using them. Satellite time is expensive though and the military would rather keep their slots open.
