I was trying to figure out what areas in North America would be most likely to have earthquakes, but I couldn't come across a good map for this. It's easy to find the areas with the highest incidence of hurricanes and tornadoes, and I know California has a high rate of earthquakes. What fault lines are there in North America (besides the obvious San Andreas fault)? Are there any maps that clearly show this?
Here is a map of seismic hazards for the United States from the United States Geological Survey. Link.
It is presence of fault zones, geological structures (like volcanos, subduction zones, tectonic plate junctions, basins, and mountains), geological evidence of past events, and record of earthquake events that go into the calculation of a seismic hazard for a specific region.
Here are a few links that may help out with your question:
