Mathematics Question

For this activity you will work in groups to complete a sample THIRA.
For this discussion activity, you will complete a sample THIRA using the four-step process. Use the THIRA worksheets download[Docx, File size 12.2 KB] provided to record your findings. Refer to your text, Chapter 9 and the Comprehensive Preparedness Guide 201: Threat and Hazard Identification and Risk Assessment (THIRA) Process Guide for examples
STEP 1: Identify Threats and Hazards
In your group, create a list of jurisdictional threats and hazards. Each group will be assigned a local jurisdiction, and should choose three threats and three hazards, one from each category (natural, technological, and human-caused).
STEP 2: Contextualize Threats and Hazards
Each group will then chose one incident from the list of three threats and hazards of significant concern identified in activity one and create a context description. This should include the conditions (at a minimum time and location) most relevant to the community. Use table 9.5 Threat and Hazard Description factors (found in chapter 9 of your text) to develop your context descriptions.
STEP 3: Establish Capability Targets
3.1 Estimate Impacts of a Threat of Hazard: Using the context descriptions developed in Step 2, choose five (5) core capabilities, one from each of the five mission areas (prevent, protect, mitigation, response, and recovery) that would pertain to managing the threat or hazard (see Table 9.1 in your text). Next, estimate impacts of the threat or hazard on the chosen capabilities.
3.2 Develop Desired Outcomes and Capability Target Statements: Using all of the information created in the previous activities, each team will develop one desired outcome for each of the five core capabilities identified in the Estimate Impacts of a Threat of Hazard activity (above). Use the estimated impacts and the desired outcomes to develop one capability target statement for each of the core capabilities.
STEP 4: Apply the Results
Apply The Results: Using the capability target statements from each of the core capabilities previously identified in Step 3, identify the necessary resources needed to request, deploy, and use to manage your incident. Your team will need to use the FEMA Resource Typing Library Tool (Links to an external site.). Calculate the resource requirements by considering the capability targets, operational capacities of resources, and time available. Present your final THIRA results to the class.
Post your findings using the THIRA Worksheet EditEdit download[Docx, File size 12.2 KB] to the discussion board.
PART B
Prepare a Threat and Hazard Identification and Risk Assessment (THIRA) calculation and summary paper for two of the threats not used by your group in the discussion forum (natural, technological, and human caused). This is an individual assignment. You are to explain each step of the process for your threat/hazard in the same format you used for the discussion activity:
Identify threats and hazards of concern
Give the threats and hazards context
Establish capability targets
Apply the results.
Refer to your text, Chapter 9 and the Comprehensive Preparedness Guide 201: Threat and Hazard Identification and Risk Assessment (THIRA) Process Guide for examples. You may use the same worksheets download[Docx, File size 12.2 KB] provided for the group discussion activity for the calculation section.
Once you have completed the THIRA calculation for each threat/hazard, you will write must include a 1-2 page summary for each that includes a brief proposal of strategies or activities that might be taken to reduce the risks to that particular area. The finished calculation and summary paper should be 4-5 pages in length.
