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., floods, wildfires, ...,) 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.
Natural Phenomena that Cause Disasters
Planet Earths atmospheric-lithospheric interactions create situ-ations favorable for Wildfires (AKA BUSHFIRES)
WILDFIRES are conflagrations caused by lightning discharges (or acts of man) in wilderness areas close enough to one or more urban interfaces that they threaten people, property, infrastructure, and business enterprise
SCIENCE OF WILDFIRES
WILDFIRE HAZARDS (AKA POTENTIAL DISASTER AGENTS)FIRE HOT GASES AND SMOKE HOT SPOTSBURNED OUT SLOPES (with increased susceptibility to insect infestation, erosion, and landslides)

AUSTRALIAS WORST WILDFIRE OUTBREAK
WORST WILDFIRES IN AUSTRALIAS HISTORY
400 FIRES BURNED FOR WEEKSVICTORIA STATE FEBRUARY 2009
The deadliest wildfires in Australia's history burned people in their homes and cars and wiped out entire towns173 DEAD; 2000 HOMES DESTROYED
WILDFIRES ON AUSTRALIAS TASMANIA ISLAND BURNED 100 HOMES AND FORCED THOUSANDS TO FLEE
JANUARY 4, 2013
WILDFIRES ON TASMANIA: (TEMPERATURE REACHED 40 DEGREES C)
OTHER WILDFIRES BURNED SIMULTANEOUSLYBushfires were also burning in other parts of Australia, including South Australia, Victoria, New South Wales and Queensland.
IMPACT IN TOWN OF DUNALLEYA SCHOOL AND A POLICE STATION WERE DESTROYED, ALONG WITH ONE-THIRD OF ALL BUILDINGS.
LESSONS LEARNED ABOUT DISASTER RESILIENCEALL WILDFIRES EARLY WARN-ING (THE ISS) AND EVACU-ATION ARE ESSENTIAL FOR DISASTER RESILIENCE
WILDFIRES REACHED CATASTROPHIC LEVEL IN AUSTRALIA
JANUARY 8, 2013
HIGH TEMPERATURES AND DRYNESS CAUSE WILDFIRES TO REACH CATASTROPHIC LEVEL
EVACUATIONFurther south on the Tasman Peninsula east of Hobart, the capitol, as many as 2,000 people took refuge in the town of Nubeena overnight, while another 700 were sheltered at the nearby historic Port Arthur site.Others were ferried to safety.
