| Abstract | Currently, there isno reliable historical documentor cultural memory of tsunami affecting Vietnam.The recent great East Japan earthquake with M9 on March 11th, 2011 provided many lessons that we can learn regarding the huge consequences and potential impact ofmegaearthquake andmegatsunamis. Several paleotsunami and paleogeologystudies have provided evident of previouseventsand indicated the potential damages of a severe tsunami offthe East coast of Honshu,Japan.However,this information somehow was not consideredby the Japanese governmentin their earthquake mitigation planning. In termsof disaster mitigation, scientists and governmental officials in Vietnam need to clarify the threat of tsunamis to the Vietnamesecoastsand reduce the risk of tsunamidamage to the country.The main objective of this research is tostudy the maximum earthquake magnitude potential in Manila Trench by applying paleotsunami and paleogeography methodology along with an assumedrupture dimension that can generatethe worst case tsunami scenario. Based on tsunami inundation depthin coastal areas combined with landuse data,census data, this research will try to identifyareas of high, moderate and lowrisk, andspecific vulnerable communities. In addition, the research willidentify existing buildings located inside the inundated zone which have enough space, accessibilityand are considered tall and strong enough so that they might be used astsunami shelters.Finally, with thecombination of tsunami evacuation buildings(destinations)with existing road network dataand anassumption of average humanwalkingspeed,thepossible shortest routes using shortest path algorithmcan be estimated. The flexibility of evacuation routeswill depend on various service areas with specific vulnerable communities and possibility of tsunami evacuation buildings. Thedecision support systemproposedin this research will be an effective toolfor local authorities tomitigate impact of tsunami in termsof evacuation fromhighrisk to safe areas. Moreover, this research will be very useful for local authorities to incorporatetsunami disaster mitigationinurban planningand management. |
