Series of layers showing recently active faults across the USA.
Five Google Earth layers from the USGS that show faults across the USA. Each file traces faults into those that were active at different times. If you hover over a fault the name of the fault will appear. If you click on the fault a text box will open with information about that particular fault. You can load in one layer at a time, or load in multiple layers – the faults are color coded according to age. These layers seem to tax slower computers though – loading all of them into Google Earth will challenge older computers to keep up.
All are KMZ files for Google Earth
