I am compiling a series of images of significant world impact structures using Google Earth and recent Landsat 8 Satellite data. The list below will take you to the relevant Impact Site page.
I have compiled a variety of data from public sources including published technical papers, geoscientific data (geology and geophysics) and produced maps summarising some of this data where appropriate. I have referenced all data sources, but if I have missed any please let me know so I can correct this.
