Geologic Interpretations based on geologic and geophysical mapping: Geologists must review many lines of evidence to validate interpretations of how the landscape we observe formed over time, and to evaluate the potential risks of natural hazard in a region. The diagram below illustrates how surficial mapping and subsurface geophysical data was used to determine have a fault-bounded block of the earth's crust in the Mojave Desert has moved over time, relative to other fault-bounded blocks in the region. Bedrock geology reconstruction helps answer many questions about the rates of motion of fault, the rates of uplift of mountain ranges or subsidence of sediment filled basins. The information provided by geologic mapping provide scientists a basis to tackle other scientific questions, such as what faults and areas are most susceptible to earthquake damage? How do faults affect the flow of groundwater in a basin? ... and much more!
