Objectives and Goals• To assess the potential tsunami disaster and its
impact to the Peruvian coast.
• To develop practical technologies to mitigate
tsunami risks in Peru.
• Implementation to the strategic plans for disastermitigation of Peruvian government.
• Contributions to Pacific tsunami disaster mitigation
strategies.

Casualty Estimation Results

VERTICALHORIZONTAL > HORIZONTAL+VERTICAL >> VERTICAL
When using vertical evacuation the number of casualties
can be reduced from 40% up to 90% compared to thecase of only horizontal evacuation, provided building
resistant and capacity is assured.
