This could be an eye-opener, if you wish to evaluate the seismic stability of your AO.
Drag the pointer to your location of choice, give it a name and 2-4-6-8, we is gonna de-agg-re-gate Word! This application computes the deaggregation of the values displayed on the 2002 USGS National Seismic Hazard Mapping Program (NSHMP) Hazard Maps for the conterminous United States and Puerto Rico. https://geohazards.usgs.gov/deaggint/2002/ |

That's telling you how far away and how big historical quakes have been.
The better graph to use is the Graphical Projection, pick Fine Angle, Fine Distance assumptions on the initial page after you have moved the map pointer to where you want.. Here is one for the area near New Madrid: 
You can see the (Miss & Ohio) Rivers, where the historical quakes have occurred, how big they are and fault lines in the area. |
