EARTHQUAKE DISASTER RESILIENCE

PART 2: Informing Community Stakeholders About Global Earthquake

Disaster Situations

Walter Hays, Global Alliance for Disaster Reduction, Vienna,

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

• 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.
