This was my first talk as a scientist. It was given to a small, mostly female audience. The atmosphere was very iighthearted which made it a lot easier to talk. The speech was about 16 minutes. The quesiton and answer went great!

Perceptions of Tsunamis

  1. 1. Toni Rosati<br />Public perceptions of tsunamis<br />
  2. 2. “Eventually, all coastal communities inCalifornia will have tsunami warning signs.” Troy Nicolini, NWS<br />
  3. 3. METHODOLOGY<br /><ul><li>Surveys taken approximately one year after sign installation in Los Angeles area beaches
  4. 4. 147 respondents in the Los Angeles coastal area were surveyed
  5. 5. 22 Likert Scale Questions, 4 Multiple Choice, 1 Qualitative Question
  6. 6. Convenience Sample Selection (In a parking lot near a tsunami sign or in a college class near tsunami innundation zone.</li></li></ul><li>Southern California is among top areas for historically damaging tsunamis.<br />1999<br />
  7. 7. RESULTS<br /><ul><li> 60% felt that tsunamis were not a threat to Los Angles
  8. 8. Devastating waves have hit the Santa Monica area as recent as 1964
  9. 9. Non-destructive events have occurred 3 times in the last 12 months.</li></li></ul><li>RESULTS<br />
  10. 10. RESULTS<br />66% think the warning signs are an effective method of public communication<br />But very few respondents were aware the tsunami warning signage and evacuation route plans existed.<br />
  11. 11. RESULTS<br />
  12. 12. The Qualitative Question…<br />
  13. 13. DISCUSSION<br /><ul><li> Most Los Angelinos remain in denial that they live near a tsunami hazard zone
  14. 14. Far too many people would NOT know what to do in the event of a tsunami. Over 42% failed to report that they would seek higher ground.
  15. 15. Respondents believe the government is being resonsible, but most have been unaware and unaffected by the efforts.
  16. 16. Many are expecting to be warned in ways that are not</li></ul>currently organized (texting, sirens) or are simply<br />impossible (newspaper).<br />
  17. 17. CONCLUSION<br /><ul><li>The dense population, expansive geography and tourism patterns should be better assessed
  18. 18. Public communication expectations must be understood
  19. 19. NOAA should make efforts to meet or adjust those expectations to match emergency management plans and capabilities.
  20. 20. Future research will include using Geographic Information Systems (GIS) to compare the population density to signage ratio of Los Angeles with successful TsunamiReady locations.</li></li></ul><li>Any Questions?<br />
