Transcript

  • 1. What is the issue?<br />Prior to the Christchurch earthquake, the word ‘liquefaction’ was very much an unknown.<br />What is your understanding of liquefaction, and through your research, in what ways, if any, can we prepare to deal with this phenomenon?<br />
  • 2. Liquefaction!<br />The hidden monster <br />
  • 3. liquefaction!<br />The unknown monster!<br />
  • 4. <ul><li>WHAT IS LIQUEFACTION
  • 5. What is Liquefaction made of ?</li></ul>Liquefaction is a layer of sandy saturated soils-soft earth<br /><ul><li>Sediment layers-loose hard material stones/rocks
  • 6. Grainy saturated layers of water</li></li></ul><li>This is our liquefaction <br />Video!<br />
  • 7. Why Does Liquefaction Occur? <br /><ul><li>The earth continues to shake
  • 8. The shaking makes the small soft sandy earth particles vibrate
  • 9. The water beneath rises up through the ground and mixes with the soft soil
  • 10. This turns the soil to a sticky wet dangerous custard, like quick-sand.</li></ul>WHAT CAN WE DO?<br /><ul><li> DO NOT build on the soft and sandy earth.</li></ul>IF NOT THEN WHAT?<br /><ul><li> Design re-in forced buildings to handle the shaking and turning of soft soil to a liquid.
  • 11. Look at the foundations of the houses and buildings being built. Make the houses move with the shaking. Make the houses sit higher above the earth. Strength the soil.</li></li></ul><li>TO CHANGE THE STRUCTURE OF THE SOIL BY PUMPING IN ANOTHER MATERIAL TO STRENGTHEN IT.<br />
  • 12. liquefaction!<br />The known monster!<br />WHEN WE KNOW WHAT THE ISSUES ARE, WHEN WE KNOW WHAT THE PROBLEMS ARE<br />THEN WE WILL KNOW HOW TO WORK TOWARD FIXING THEM      1. Learn which homes and structures were affected, and which ones weren’t.<br />2. Design more earthquake-liquefaction resistant homes.<br />3. Educate locals to build their skill sets using disaster-resistant technologies.<br />4. Stimulate local demand for new types of housing and design.<br />5. Measure the change over time.<br />
