LESSONS LEARNED FROM PAST NOTABLE DISASTERSAUSTRALIAPART 2: CYCLONES

NATURAL HAZARDS THAT HAVE CAUSED DISASTERS IN AUSTRALIA
GOAL: PROTECT PEOPLE AND COMMUNITIES
HIGH BENEFIT/COST FROM BECOMING DISASTER NRESILIENT
GLOBAL CLIMATE CHANGE
Planet Earth’s atmospheric-hydrospheric-lithospheric interactions create situations favorable for CYCLONES
A DISASTER is ---
--- the set of failures that overwhelm the capability of a community torespond without external help when 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 space and 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.

HIGH POTENTIAL LOSS EXPOSURES IN A CYCLONE
A communities people, property, essential and critical infrastructure, business enterprise, government centers, crops, wildlife, and natural resources.
CAUSES OF DAMAGE
WIND PENETRATING BUILDING ENVELOPE
UPLIFT OF ROOF SYSTEM

ALL CYCLONES PREPAREDNESFOR THE EXPECTED AND UNEXPEDTED IS ESSENTIAL FOR DISASTER RESILIENCE
ALL CYCLONES EARLY WARNING IS ESSENTIAL FOR EVACUATION AND PREPARATION OF THE LAST LINE OF DEFENSE, WHICH ARE ESSENTIAL FOR DISASTER RESILIENCE
TIMELY EMERGENCY RESPONSE IS ESSENTIAL FOR DISASTER RESILIENCE
SOME OF AUSTRALIA’S WORST CYCLONES
Cyclone TRACY: 1974
Cyclone LARRY: 2006
Cyclone HAMISH: 2009
Darwin was rebuilt using modern materials and updated building practices that incorporated wind engineering
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 HAMISH’S IMPACTS
Hamish was a CAT 4 storm with 290 kph (175 mph) winds
Coal exports were disrupted
The tourist industry was slowed.
It caused a major oil spill.
RECOVERY AND RECON-STRUCTION IS ABOUT KNOW-ING WHAT TO DO DIFFFERENTLY WHEN START-ING OVER AGAIN.
