Eugene -Springfield Area Natural Hazards Mitigation Plan 2. Hazard Descriptions • Except for natural systems, all sectors are extremely sensitive to a magnitude 9.0 CSZ earthquake incident. • Very little has been done to prepare any systems, infrastructure, or personnel to handle the initial impact and ongoing response and recovery from a CSZ incident. • Exceedingly limited staff availability in the aftermath of a severe earthquake will create problems and challenges difficult to predict or mitigate. • Every sector will experience substantial failures and interruptions unfamiliar to the area and therefore difficult (though possible) to plan for. • Very few Eugene and Springfield residents have first- hand experience with a major earthquake, making it difficult to describe the potential experience and results. Additional system vulnerability details are included in Section 4 as part of the 2014 Climate and Hazard Vulnerability Assessment Report. In 2007, the Oregon Department of Geology and Mineral Industries (DOGAMI) completed a rapid visual screening (RVS) of educational and emergency facilities in communities across Oregon, as directed by the Oregon legislature in Senate Bill 2 (2005). RVS is atechnique, used by the Federal Emergency Management Agency (FEMA), known as FEMA 154, to identify, inventory, and rank a building's potential vulnerability to seismic incidents. DOGAMI surveyed a total of 3,349 buildings, giving each a low, moderate, high, or very high rating for collapse potential from a high magnitude earthquake. The RVS assessed a total of 174 buildings in the Eugene -Springfield area. 30 It is important to note these rankings represent a probability of collapse based on limited observed and analytical data and are therefore approximate rankings. To fully assess a building's collapse potential, a detailed engineering study completed by a qualified professional is required, but the RVS study can help prioritize which buildings to survey. Table 2-2 shows the number of Oregon education and emergency services buildings surveyed in Eugene and Springfield with their respective rankings. Based on the RVS study, Eugene and Springfield performed further seismic evaluations on much of their critical infrastructure. These more detailed assessments resulted in a prioritized list of facilities in need of seismic retrofits. Several of these sites have already undergone seismic retrofitting work, and funding for more projects is being actively pursued. 30 United States.
