22. Tsunami Intensity Scale* ( = rho * u^2 * depth) High intensity Medium intensity Low intensity *This can be calculated by TSUNAMOS Proposed Research

23. We have existing information on what types of buildings are in a community Steel reinforced concrete (modern hotel) Unreinforced CMU (old hotel) Timber Frame (residential) Proposed Research

24. Use ‘limit states’ to get probabilistic estimate of expected damage Damage depends on both the ‘intensity’ of tsunami and the type of structure Legend Building survives Building damaged Totally destroyed Proposed Research

25. Outcome: Produce allows Structures to be identified for potential ‘vertical evacuation shelters’ Or … Proposed Research

26. … Identify places where new shelters will reduce the loss of life Proposed Research
