On the Home tab under Slides, click Section, and then click Add Section.NotesUse the Notes pane for delivery notes or to provide additional details for the audience. You can see these notes in Presenter View during your presentation. Keep in mind the font size (important for accessibility, visibility, videotaping, and online production)Coordinated colors Pay particular attention to the graphs, charts, and text boxes.Consider that attendees will print in black and white or grayscale. Run a test print to make sure your colors work when printed in pure black and white and grayscale.Graphics, tables, and graphsKeep it simple: If possible, use consistent, non-distracting styles and colors.Label all graphs and tables.
  • Discuss outcomes of the case study or class simulation.Cover best practices.
  • Give a brief overview of the presentation. Describe the major focus of the presentation and why it is important.Introduce each of the major topics.To provide a road map for the audience, you can repeat this Overview slide throughout the presentation, highlighting the particular topic you will discuss next.

  • 1. EARTHQUAKES SEAN ROBERTSON CHRISTIAN LESSEY NATE BOWERS DECEMBER 12, 2013
  • 2. Earthquakes • • • • • • Earthquakes can happen anywhere Missouri Florida California Utah These are just a few places, not a full list
  • 3. EARTHQUAKES • Most earthquakes happen in the ocean however • Alaska has a lot since 1899 to present it has had 49 major earthquakes M 7.0 or higher • Every state in the U.S. has had an earthquake
  • 4. Ring of Fire
  • 5. Earthquakes in Alaska
  • 6. Alaska • March 9 1957 Andreanof Island has a M 8.6 • Bridges are damaged docks destroyed and it even caused Mount Vsevidof to Erupt which was dormant for 200 yrs. • Caused a Tsunamis which continued to Hawaii, California, Chile, El Salvador, and Japan • More than 300 aftershocks where reported
  • 7. Alaska • They also had earthquakes on March 12, 14, 16th all on Andreanof Island • On the 9th there was also an earthquake on Fox island • They were all over M 7.0
  • 8. Alaska • July 10, 1958 Lituya Bay, Alaska has a M 7.7 earthquake • Not much damage to man made works minimal since there was not much in alaska • Landslides reported in the mountains
  • 9. Earthquakes in Alaska
  • 10. Practice
  • 11. ALARM SOUND and DRILL
  • 12. Great Shake Out Drills Steps during and Earthquake • Drop • Cover • Hold on http://www.youtube.com/watch?v=bAHNhtRT50A

  • 14. The Great Alaskan Earthquake of 1964
  • 15. The Initial Event •Occurred Friday, march 27th 1964 at 5:36 P.M. •Lasted three minutes
  • 16. Aftershocks • Thousands of large aftershocks that were felt up to three weeks after the initial event • Caused many landslides and subsidence • Up to magnitude 7 • Some occurred up to a year later
  • 17. Epicenter • Epicenter was located 12.4 miles north of Prince William Sound, 78 miles east of Anchorage
  • 18. The earthquake registered at 9.2Mw
  • 19. The Damage • Caused $311 million (2.26 billion in current U.S. dollars) in Alaska and other places • Cleanup took 15+ years to complete
  • 20. Tsunamis and Surge Waves • The quake and its aftershocks created tsunamis that caused damage in California, Hawaii and Oregon • The tsunamis were up to 30ft tall • Some water levels were up to 80ft above sea level • The towns of Whittier, Valdez, and Kodiak were almost completely destroyed
  • 21. Surge Wave Damage Kodiak, AK
  • 22. Surge Wave Damage Seward, AK
  • 23. Deaths Caused • 128 people killed – 113 from the tsunamis – 15 from the earthquake • The death toll would have been much greater had the quake occurred present day
  • 24. Subsidence • The earthquake created grabens up to 8ft deep
  • 25. Tectonic Uplift
  • 26. Both of these areas were more than 30ft underwater before the event. The quake caused the land in some places to rise so rapidly that trees were torn in half.
  • 27. Fissures The earthquake left large fissures in roads and bedrock, some were up to 6ft wide
  • 28. Earthquakes Seismic waves & Destruction of property
  • 29. • Different motions of Earthquakes.
  • 30. • Are the fastest waves and are the first waves recorded by seismographs. Some call P-waves push-pull wave because of the way they contract and expand as they are traveling
  • 31. Visual example of a p-wave
  • 32. S-Waves can’t travel through liquids or gases. They require rigid material like ground, rock, roads or buildings
  • 33. Visual example of a S-wave
  • 34. Human interaction • Base isolation bearings
  • 35. Elastic Cables Steel frame Shoes Steel fuses (in blue)
