Lamar County Multi- Jurisdictional Hazard Mitigation Plan Chapter Three *Example: If Lamar County has had 10 tronado years recorded in the last 100 years 10/100 = 0.10 average peryear, which would make tornadoes "Unlikely" to occur within the County 6.Vulnerabilit3L: Vulnerability describes how exposed or susceptible to damage the count is in terms of why and where the hazard can occur within the county and /or the sixteen jurisdictions. The vulnerability is the risk of future occurrences. HAWS, THMP, and other local data were used to establish a base map and conduct a risk assessments. 7. Secondary Hazards: Lists other hazards often triggered by the identified natural hazard event. Some natural disasters set off other types of catastrophes in a cascade of effects that lead to a highly complex situation. Secondary hazards can be events such as transportation and communications disruptions, fire, hazardous materials dispersion, power outages, and other utilities disruptions. These secondary events are identified along with the associated primary hazard due to how they can dictate the amount of impact a natural hazard event can have on the county and /or the sixteen jurisdictions. 8. Overall Summary of Vulnerability and Impacts: This section summarizes the vulnerability of the entire county and the possible impacts of the natural disaster. The following table represents the priority risk index of hazards facing Lamar County and its jurisdictions. 52 Probability of Future Events: (30% of Priority Risk Index) HfglirY Tlk6e Event probable in the next year. dex Value =4 `` • 1/1 = 1.00 Greater than .33 Likely • Event probable in next 3 Years Index Value = 3 • 1/3 = 0.33 Greater than 0.20, but less than orequal to 0.33 Occasional • Event Probable in next 5 years.
