Natural Phenomena that Cause Disasters

Planet Earth’s atmospheric-lithospheric interactions create situations favorable for Wildfires (AKA BUSHFIRES)

CHILE’S CITIES

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

LOCATIONS OF 2012’S NOTABLE 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)

NOTABLE WILDFIRES IN CHILE

2012’s wildfires - the worst Chile has seen in years - were worsened by

strong winds, high temperatures and exceptionally dry conditions

Chile's southern regions, normally experiencing rain in

January, were suffering instead from a nationwide

heat wave on top of a drought; two factors that

make wildfires more likely.

LOCATIONS

Nearly 50 wildfires in southern Chile destroyed hundreds of

houses, forced the evacuation of thousands of people, and caused millions of dollars in damage to the forestry and

tourism industries.

WILDFIRE IN BIO BIO REGION: JAN. 4, 2012

• The worst of the blazes were concentrated in Chile's Bio Bio region, where about 24,800 hectares were destroyed

WILDFIRE IN BIO BIO REGION: JAN. 4, 2012

• Helicopters fight a massive forest fire affecting the commune of Ranquil, in southern Chile's Bio Bio region, 450 km (275 mi) south of Santiago.

FIGHTING THE BIO BIO WILDFIRES

IMPACTS: WILDFIRES IN BIO BIO REGION: JAN. 4, 2012

• 600 people were evacuated from the area

• 160 homes destroyed.

WILDFIRE IN ARAUCANIA REGION: JAN. 5, 2012

• Seven firefighters died after being trapped by flames when the wind suddenly changed direction.

• They were part of a team trying to extinguish a blaze near Carahue in the Araucania region, about 700 km (434 miles) south of the capital Santiago.

A DISASTER CAN HAPPENWHEN THE

POTENTIAL DISASTER AGENTS OF A WILDFIRE INTERACT WITH

CHILE’S COMMUNITIES

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., wildfires, 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.

THE REASONS ARE . . .

• When it does happen, the functions of the community’s buildings and infrastructure can be LOST.

THE REASONS ARE . . .

• The community is UN-PREPARED for what will likely happen, not to mention the low-probability of occurrence—high-probability of adverse consequences event.

THE REASONS ARE . . .

• The community has NO DISASTER PLANNING SCENARIO or WARNING SYSTEM in place as a strategic framework for early threat identification and coordinated local, national, regional, and international countermeasures.

THE REASONS ARE . . .

• The community LACKS THE CAPACITY TO RESPOND in a timely and effective manner to the full spectrum of expected and unexpected emergency situations.

THE REASONS ARE . . .

• The community is INEFFICIENT during recovery and reconstruction because it HAS NOT LEARNED from either the current experience or the cumulative prior experiences.
