A DISASTER is ---

--- the set of failures that overwhelm the capability of a community to respond 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., floods, wildfires, ...,) 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.

Natural Phenomena that Cause Disasters

Planet Earth’s 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

WILDFIRE HAZARDS

SCIENCE OF WILDFIRES

WILDFIRE HAZARDS (AKA POTENTIAL DISASTER AGENTS)

• FIRE

• HOT GASES AND SMOKE

• HOT SPOTS

• BURNED OUT SLOPES (with increased susceptibility to insect infestation, erosion, and landslides)

WILDFIRES TO REACH “CATASTROPHIC LEVEL”

EVACUATION

• Further 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.
