  • Natural Phenomena that Cause Disasters

    Planet Earths atmospheric-hydrospheric-lithospheric interactions create situations favorable for CYCLONES

  • A DISASTER is --- --- the set of failures that overwhelm the capability of a community to respond without external helpwhen three continuums: 1) people, 2) community (i.e., a set of habitats, livelihoods, and social constructs), and 3) complex events (e.g., cyclones, floods,...) intersect at a point in spaceand time.

  • Disasters are caused by single- or multiple-event natural hazards that, (for various reasons), cause extreme levels of mortality, morbidity, homelessness, joblessness, economic losses, or environmental impacts.

  • SEVERE WINDSTORM HAZARDS

  • HIGH POTENTIAL LOSS EXPOSURES IN A CYCLONEA communities people, property, essential and critical infrastructure, business enterprise, government centers, crops, wildlife, and natural resources.

  • SOME OF AUSTRALIAS WORST CYCLONESCyclone TRACY: 1974Cyclone LARRY: 2006Cyclone HAMISH: 2009

  • CYCLONE TRACY

  • CYCLONE TRACYS PATH

  • IMPACTS OF CYCLONE TRACYCyclone Tracy devastated the city of Darwin in Australias Northern Territory from Christmas Eve to Christmas Day, 1974.

  • IMPACTS OF TRACYTracy killed 71 people, caused AS837 million in damage (1974 dollars) and destroyed more than 70 percent of Darwin's buildings, including 80 percent of the houses.

  • IMPACTS OF TRACYMore than 30,000 of Darwins 47,000 inhabitants were evacuated from Adelaide, Whvalla, Alice, Springs, and Sydney.Many never returned to Darwin.

  • AFTER TRACYDarwin was rebuilt using modern materials and updated building practices that incorporated wind engineering

  • CYCLONE LARRY

  • QUEENSLAND

  • Larry made landfall in far North Queensland close to Innisfail on 20 March 2006 as a Category 4 with wind gusts reaching 240 kilometers per hour (150 mph), and dissipating over land soon afterward.

  • CYCLONE LARRY: MARCH 15-20, 2006

  • CYCLONE LARRYS TRACK: MARCH 15-20, 2006

  • LARRYS IMPACTSThroughout Queensland, Cyclone Larry resulted in A$1.5 billion ($1.1 billion USD) in damage, making Larry, at that time the costliest tropical cyclone to ever impact Australia, surpassing 1974s Cyclone Tracy loss.

  • CYCLONE HAMISH

  • CYCLONE HAMISH: MARCH 4-11, 2009

  • CYCLONE HAMISH TRACK MARCH 4-11, 2009

  • CYCLONE HAMISH

  • CYCLONE HAMISHS IMPACTS

    Hamish was a CAT 4 storm with 290 kph (175 mph) winds Coal exports were disruptedThe tourist industry was slowed. It caused a major oil spill.

  • HEAVY RAINFALLHamish produced heavy rainfall over North Queensland with accumulations of 300 mm (12 in) in some areas. Mackay recorded 284 mm (11 in) in 2 days, and in combination with high tide, Hamish produced a 6.3 m (20.6 ft) tide in Mackay, flooding some streets.

  • CYCLONE HAMISH: OIL SPILL IMPACTS BEACHES

  • THE NEXT CYCLONE SEASON IS ON THE WAYCYCLONE DISASTER RESILIENCE IS NOT AN IMPOSSIBLE DREAM!

  • LESSONS LEARNED ABOUT DISASTER RESILIENCEALL CYCLONES RECOVERY AND RECON-STRUCTION IS ABOUT KNOW-ING WHAT TO DO DIFFFERENTLY WHEN START-ING OVER AGAIN.
