In the Tennessee Valley many major categories of disasters are experienced which include natural disasters and man-made and looking into the main difference between them it’s importance in increasing overall knowledge of occurrences, causes of each and ensuring that your preparedness is intensified. In addressing terms of catastrophic, critical, marginal, negligible, improbable, remote, occasional, probable, and frequent and should be simple and concise using numerical and non-numerical descriptions and create a matrix for easy referencing. The process should report the terms hazard, risk, and causal factor and how causal factor seems to confuse the analysis of hazards in a pyramid of "effect, mishap, hazard, causal factor" when the factor is simply another word for hazard. Hazards should be broken down to the level where you are able to apply mitigation. Severity or risk, what is an "acceptable risk" and is it based on history, personal experience, or public pressure or based on heightening risk with the constraints of "hazards" versus "failure conditions". Improvement of information dissemination between responders and planners in the community and local government this can be accomplished by improving public understanding of the discipline, promoting and improving System Safety as a profession, promotion within jurisdictions and managing activities and objectives . Natural disasters are caused by natural phenomenon or acts of God. The extent of loss is usually based on the level of information to the public, readiness of first responders and the cooperation between emergency management at the city, county and state level. As such, this can occur in areas susceptible to vulnerability. In retrospect, man-made disasters are directly influenced by humans from negligence, human error or direct malicious intent and include occurrences such as floods (wetlands, lower elevations with high rainfall amounts and co-location with a major dam). Activity occurs regularly as Tennessee has numerous bodies of water, low lands and flood plains.

The past twenty or thirty years we have experienced sinkholes and millions of dollars spent to avert major infrastructure damage. Earthquakes are experienced along the New Madrid Seismic Zone, also called the New Madrid Fault Line, this is a...
