to add, that nasty red bump in the center is right on the new madrid fault zone which is responsible for one of the worst earthquake in US history.  Worse it likes to drop swarms not single events. Alaska has somnastier ones though, https://en.wikipedia.org/wiki/1964_Alaska_earthquake

<p>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?</p>

There are very few places in the U.S. where there aren't faults. Please read up on faults ([like this Wikipedia article](https://en.wikipedia.org/wiki/Fault_(geology))) and try to narrow the focus of your question. Here's [an interactive map of just the most recent active faults](http://usgs.maps.arcgis.com/apps/webappviewer/index.html?id=db287853794f4555b8e93e42290e9716).

I must say, I was pretty useless at finding a good map of major faults in NA, so maybe it's less obvious than it sounds.  Stephanie, it does appear that there are a ton of faults out there, though, as https://en.wikipedia.org/wiki/Template:California_Faults shows

To ad red to @Spencer's comment. Some faults in the US have been reactivated by fracking. Regions that rarely experienced earth quakes, now experience quakes since fracking commenced in & near those areas

I reopened this question as @JeopardyTempest makes a good point that a map of this is hard to come by.

# Fault Lines in North America

(Asked by: username_0 on 2017-12-14)

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](https://earthquake.usgs.gov/hazards/hazmaps/).

[![Seismic hazard map for the lower US](https://i.sstatic.net/Q3TEy.jpg)](https://i.sstatic.net/Q3TEy.jpg)

[Link](http://usgs.maps.arcgis.com/apps/webappviewer/index.html?id=db287853794f4555b8e93e42290e9716) to interactive fault map for the US (source: USGS)
Here is a [link](https://www.wired.com/2008/10/five-us-earthqu/) to a nice article on top 5 earthquake prone areas outside California.

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.
