| Summary: | Structures such as dikes play a crucial
role in preventing disasters by controlling tsunamis,
floods, debris flows, landslides, and other natural
phenomena. However, structural measures alone cannot prevent
all disasters because they cannot mitigate damages when the
hazard exceeds the level that the structures are designed to
withstand. The Great East Japan Earthquake (GEJE)
demonstrated the limitations of Japan's existing
disaster management systems, which relied too heavily on
dikes and other structures. Damage can be kept to a minimum
by multilayered approaches to disaster mitigation that
include structural and nonstructural measures and that
ensure the safe evacuation of residents. This report gives
findings; lessons; and recommendations for developing countries. |
