The U.S. hazard map showing the highest hazard areas in black and the lowest hazard areas in gray.

The new U.S. stress map. The colors show the style of faulting – red is normal faulting, white is strike-slip, and blue is thrust. The black lines show the direction of the stress. The 3 locations in the central U.S. that are different than the areas around them are the regions of highest hazard on the U.S. hazard map (below).Click here to read:
