Faults are classified by age of last known movement.
Download all 5 layers as a ZIP file .


  • Faults are colored coded for age category.
  • As you hover the cursor over a fault, it's name will appear in the same color as the fault.
  • If you click on the fault, a text box will open and you can click a link for the database of information about that fault.
  • Sometimes it takes two clicks to get the text box to open.

You can also access a fault through the Google Earth table of contents. Open the folder for the correct age, find the fault name in the list, and double click the name. Google Earth will "fly" to the fault you selected.


Google Earth software enables you to zoom in beyond the level of accuracy provided in these data layers. Fault traces are depicted at their mapped location on the surface. Most faults dip one way or another at depth, and their location must be modeled or inferred from geologic evidence. Fault dip information is included for each fault within the application.
