Nobuko Goto 津波
* The height of Tsunami was higher than estimated height by government * The height of Tsunami was higher than multistory buildings Japan Tsunami Damage Northeastern Japan was hit by a massive earthquake and Tsunami on March 11, The damage was worse; The height of Tsunami was higher than the level estimated by government Local people are not used to Tsunami Preparedness breakwater
New Tsunami Preparedness approach Source: Shizuoka Prefecture,http://www.e-quakes.pref.shizuoka.jp/shiraberu/hinan/05/04.html Tsunami Expected Inundation areas Evacuation areas Tsunami evacuation multistory building About 200 meters High Low
Research Questions Using Tsunami preparedness approach of Tsunami evacuation buildings, Which areas are missing with tall buildings for evacuation? Which areas would have more damage by Tsunami ? Which areas government should begin, if this policy approach is adopted?
Study Area California 2000m Malibu Santa Monica Redondo Beach Rancho Palos Verdes
Covered Areas by existing structures (200 and 500 m) * Average male walking (80m/minutes)- 200m: 2.5 minutes, 500m: 6.25 minutes Total number of buildings in the hazard area: 25,4391
Possible heavy damage locations Influence factors Low elevation Old age of building High percentage of elderly people Close distance
2. Age of building
3. Proportion of elderly people
Missing Evacuation Areas with high priority Aggregate elements and find possible areas of heavy damage Parameters and weight ParametersLevelWeight Elevation250% Distance425% Percentage of elderly315% Age of building *210% * I weighed this parameter only 10%, because the minimum size of survey is block group.
Model - reclassifying
Possible damage areas High Low
High priority areas for Tsunami preparedness Manhattan Beach ~ Hermosa Beach Between Marina Del Rey and LAX Areas close to Malibu beach coast Around Santa Monica Airport High Low
