Eugene -Springfield Area Natural Hazards Mitigation Plan <br />Uieh <br />Model Itc <br />Low <br />1. Mitigation Planning <br />is a source of harm or difficulty created by a meteorological, environmental, or <br />geological event. Impacts are the consequences or effects of a hazards on the <br />community and its assets.7 For this update, four significant impacts or cascading <br />incidents: civil unrest; dam or levee failures; epidemics; and hazardous material <br />spills or releases, were viewed as secondary life threats to the primary natural or <br />biological disaster. These incidents can occur absent of a natural hazard, but such <br />an incident would be human caused, and not due to a natural force; the focus of <br />this plan. <br />For each hazard the likelihood of it causing one of the four cascading incidents <br />was evaluated and categorized (Figure 1-1 and Table 1-2). A summary of the <br />natech (natural hazard trigged technological disasters) evaluation process is <br />included in Section 4 and an in-depth review of the natech impacts for each <br />natural hazard is located throughout Section 2. <br />Hazard Impacts Risk Profile <br />Civil Dam or Levee Epidemics Hazardous <br />Unrest Failure Materials <br />Figure 1-1.
