Padang is capital city of West Sumatera whose coastal layout and approximately 50% of population live in low area. It opposites to the Indian Ocean which near the Megathrust subduction which can trigger a powerful earthquake and generate tsunami. Because of the potential risk, important to finding the final evacuated region (TEA) location addressed by evacuee of each affected village, and defining the evacuee population and its susceptive population on each TEA. Defining the location TEA is provided by formulating the linear programming model which minimizing the total traveled distance. Then, defining of population and susceptive of evacuee in each TEA also analyzed to support the response disaster occurred. The optimization model is conducted in three level scenarios of tsunami scale, that are big, medium, and small .

In this paper we investigate how well residents of the Andaman coast in Phang Nga province, Thailand, are prepared for earthquakes and tsunami. It is hypothesized that formal education can promote disaster preparedness because education enhances individual cognitive and learning skills, as well as access to information. A survey was conducted of 557 households in the areas that received tsunami warnings following the Indian Ocean earthquakes on 11 April 2012. Interviews were carried out during the period of numerous aftershocks, which put residents in the region on high alert. The respondents were asked what emergency preparedness measures they had taken following the 11 April earthquakes. Using the partial proportional odds model, the paper investigates determinants of personal disaster preparedness measured as the number of preparedness actions taken. Controlling for village effects, we find that formal education, measured at the individual, household, and community levels, has a positive relationship with taking preparedness measures. For the survey group without past disaster experience, the education level of household members is positively related to disaster preparedness. The findings also show that disaster related training is most effective for individuals with high educational attainment. Furthermore, living in a community with a higher proportion of women who have at least a secondary education increases the likelihood of disaster preparedness. In conclusion, we found that formal education can increase disaster preparedness and reduce vulnerability to natural hazards.
