The following website provides assistance when performing risk assessment for Texas Residents:
Texas Hazard Mitigation Package (THMP)

I found the databases helpful in determining the types of natural disasters (tornado, hurricane, earthquake, etc) that have occured in my neck of the woods. At least it would allow me to prioritize some of my planning to address the more likely risks (tornados in Dallas-Ft Worth area).

For those who are data impaired, you can using their existing map program to have a graphical representation. Yup, I need to draw a picture to figure it out.

Perhaps others can provide links to information provided by their state governments.
