RESILIENCE
PART 2: Informing Community
Stakeholders About Global Earthquake
Disaster Situations
Walter Hays, Global Alliance for
Disaster Reduction, Vienna,
Virginia, USA
The Process of Becoming an
Informed Community Stakeholder
is Like Learning How to Fly a
Plane Using A Flight Simulator
so: SIMULATE GLOBAL
EARTHQUAKE SITUATIONS
UNTIL THEY BECOME YOUR REALITY

TOOLS FOR ENACTING AND
IMPLEMENTING POLICIES ON
PREPAREDNESS, PROTECTION,
SCENARIOS, EMERGENCY RESPONSE,
and RECOVERY & RECONSTRUCTION
• OCCURRENCE
(PLATE TECTONICS, LOCATION, FAULTING,
SEISMICITY, …)
Earthquakes occur as the result of
global interactions between and
within tectonic plates in the
lithosphere that are slowly moving
past each other as the result of
stresses created by heat flow from
deep inside the Earth.
