Eugene -Springfield Area Natural Hazards Mitigation Plan 4. Risk and Vulnerability are extremely vulnerable to a Cascadia Subduction Zone (CSZ) earthquake. 84 Exceedingly limited staff availability in the aftermath of a severe earthquake will create problems and challenges difficult to predict or solve in advance. Every sector will experience substantial failures and interruptions. Some possible impacts from a large earthquake can be anticipated and others may not. Unanticipated impacts and the sheer magnitude of a large earthquake will challenge local, State, and Federal preparedness and response efforts. Very few residents have first-hand experience with a major subduction zone earthquake, making the potential experience and results difficult for the population to fully prepare for and survive without significant resources from outside of the area. Since the completion of the Vulnerability Assessment and the 2014 NHMP, both Eugene and Springfield conducted seismic evaluations on some critical infrastructure of concern. 4.5 Vulnerability Assessment — Process In 2013 staff from the City of Eugene and the City of Springfield, with support from Oregon Partnership for Disaster Resilience (OPDR), convened meetings with representatives from each of the crucial sectors. The team met for six hours with each sector. Working from a standard list of questions, the team collected information about the adaptive capacity and sensitivity to specific hazards. The sector summaries below are the result of these interviews and reflect the conversations and thinking of the participants. The Participant List in Section 4.2.6 of the 2014 Regional Climate and Hazards Vulnerability Assessment catalogs those system managers who provided their expertise. 85 The 2014 Assessment became the foundation of the 2014 Eugene -Springfield Natural Hazard Mitigation Plan and allowed staff to identify gaps in information. The Vulnerability Assessment continues to be the foundation of the 2020 Eugene - Springfield NHMP. The Risk Matrix (Table 4-2) has been, and will continue to be, modified as additional studies are completed to ensure this document is accurate. The following sections describe the methodology and results of the 2014 Vulnerability Assessment in more detail. Figure 4-3 shows the process flow leading to ascertaining the results. 84 United States. Oregon Seismic Safety Policy Advisory Commission.
