Session 8 Slide Deck
Session 8 2
Session Objectives
1. Discuss the hazard identification process and strategies
2. Discuss the Hazard Analysis Process
3. Detail International Examples of Hazard Profiles
Session 8 3
Hazard Identification Factors
• Geologic• Meteorological• Hydrologic• Biological• Economic• Technological• Political• Social
Session 8 4
Hazard-Specific Approach• Resources may be limited to only those hazards
that present an actual threat• Mitigation methods, which actually do address
hazards individually, can be more easily identified and subsequently prioritized
• Hazard specific expertise and equipment may be acquired to address the unique response needs of certain hazards
• Hazard risk can be mapped out to better delineate the geographic limits of risk, and thus allow for the prioritization of resources and effective land use planning.
Session 8 5
Hazard Identification
• Must be exhaustive and inclusive• Product: “a detailed list of all hazards that
have caused disasters in the past or that have the potential to result in future disaster events, becomes the basis of the hazards risk management process”
Session 8 6
Hazard Profiling
• Hazard profiling is a process of describing the hazard in its local context– A general description of the hazard– A local historical background of the hazard– Local vulnerability– Possible consequences– Estimated likelihood
Session 8 7
Hazard Identification Methods
Prescriptive or Creative• Brainstorming• Research on the disaster / emergency history• Review of existing plans• Similar hazard identification efforts• Mapping / GIS• Interviews• Site visits• SMEs• Hazard Mitigation Officer• Hazard Maps• Checklists

• Geography• Property• Infrastructure• Demographics• Response Agencies
Session 8 13
Risk Statement Components• Name of the Hazard• General Description of the Hazard• Frequency of Occurrence of the Hazard
– Historical Incidence– Predicted Frequency
• Magnitude and Potential Intensity• Location(s) of the Hazard• Estimated Spatial Extent of Hazard Impact• Duration of Hazard Event, Emergency, or Disaster• Seasonal Pattern / Time-Based Pattern• Speed on Onset• Availability of Warning
