To provide to the public a digital geologic map database of the elements of infrastructure and seismic hazard in the central United States.

How was the data set created?

1. From what previous works were the data drawn?

   Wheeler and others (1994) (source 1 of 1)

   Wheeler, R.L., Rhea, Susan, and Tarr, A.C., 1994, Elements of infrastructure and seismic hazard in the central United States in the central United States, in Shedlock, K.M., and Johnston, A.C. eds.: U.S. Geological Survey Professional Paper 1538-M.

2. How were the data generated, processed, and modified?

3. What similar or related data should the user be aware of?

How reliable are the data; what problems remain in the data set?

1. How well have the observations been checked?

2. How accurate are the geographic locations?

3. How accurate are the heights or depths?
