| Summary: | Hazard and risk assessments are the
crucial first step in disaster risk management (DRM) and the
basis for formulating DRM policies. They must take into
account worst-case scenarios in the event of the largest
possible hazard, while recognizing that hazard assessments
of earthquakes and tsunamis will always have their
limitations and associated uncertainties. In Japan so-called
hazard maps, that combine hazard information with evacuation
routes and locations of evacuation centers, are effective
tools for promoting evacuation procedures and risk awareness
among the public. However, in the case of the Great East
Japan Earthquake (GEJE), these hazard maps, created before
the event, may have given people a false sense of security
by underestimating the disaster's potential impact.
Hazard maps should be designed to guide and facilitate
prompt evacuation. They should be easy to understand and
readily available. This report gives findings; lessons; and
recommendations for developing countries. |
