“DISASTER

LABORATORIES”

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. windstorms, 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 type of events.

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.
