<br /> <br />2021 Multijurisdictional Local Hazard Mitigation Plan <br /> <br />Source: National Centers for Environmental Information, 2018 <br /> <br /> Figure 15-8. 1700 Cascadia Subduction zone Earthquake Tsunami Event <br /> <br /> <br /> Present building codes and guidelines do not adequately address the impacts of tsunamis on structures. <br />Planning partners, especially the Cities of Half Moon Bay and Pacifica, should review their building code <br />and consider requirements for tsunami-resistant construction standards in vulnerable areas. <br /> As tsunami warning technologies evolve, the tsunami warning capability within the planning area will <br />need to be enhanced to provide the highest degree of warning to planning partners with tsunami risk <br />exposure. <br /> Special attention will need to be focused on the vulnerable communities in the tsunami zone and on <br />hazard mitigation through public education, outreach, and warning capabilities. This issue may be <br />especially important for visitors to San Mateo County. <br /> Risk from tsunami inundation is not subject to the State of California real estate disclosure law at this <br />time. <br /> Structures in the planning area built before the cities and County entered the NFIP may not be designed to <br />resist tsunami forces. <br /> With future impacts from climate change, the issue of sea level rise may become an important <br />consideration as probable tsunami inundation areas are identified through future studies. <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br />15-14
