It is also one of the most complex. This stems partially from its three-dimensional nature — it deals not only with the surface of the earth, but to a depth of many miles beneath. Adding to the complexities is yet another dimension — time.

One LandSat imagery study will shed new information on fractures, faults, and fault systems in the earth's crust, and their relationship to mineralization. Also, knowledge about earthquake hazards might be Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original United States.
