  4. Consequences and Aftermath of Hazard • Damage were $16.5 million, $1.4 billion when you account for inflation • Nine schools across three states were destroyed, killing sixty nine students • 15,000 homes were damaged • The tornado also affected Kentucky, Tennessee, Alabama, Kansas and other states

  8. Frequency: • The tri-state tornado was part of a larger tornado out break consisting of eight other tornadoes

  9. Duration: • 3.5 hours

  10. Extent: • Larger area

  11. Speed of onset: • They saw it coming, but they didn’t realize it was going to be as bad as it was till it hit

  12. Spatial Dispersion: • The three states would be likely to be affected by this particular event • The demographic receives many tornadoes a year on average • Most times, tornadoes occur in outbreaks, not just a single tornado

  13. Temporal Spacing: • It started with showers and cooling temperatures (nothing strange) • The forecast was tracking a cold, lower-pressure system that bent down from western Canada into Wyoming. • The jet stream wasn’t discovered until World War II by Japanese scientists.

  14. Work Cited • Hearst Communications. (July 31, 2007) There’s never been another tornado like it.Retrieved October 20th 2009, from http://www.popularmechanics.com/science/worst_case_scenarios/4219867.html • google
