Planet Earth’s heat flow causes movement of lithospheric plates, which causes faulting, which causes EARTH-QUAKES

A DISASTER CAN HAPPENWHEN THE

POTENTIAL DISASTER AGENTS OF AN EARTHQUAKE INTERACT WITH TURKEY’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., earthquakes, 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 will be LOST because they are UNPROTECTED with the appropriate codes and standards.


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


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