This project analyzed the effect that a tsunami's impact, with different wave ranges would have on the population and facilities of the Greater Vancouver region. It was found that while most study is done over the Vancouver main city of the region, the area of Richmond and Delta which have repeatedly been shown to be the most vulnerable places in the event of a tsunami, have very little options for mitigation due to their specific location as islands only connected to the mainland through bridges. However, bridges are very likely to be either under water or very damaged if a 10meter tsunami occurs, therefore as further research should go, mitigation responses such as least cost path should incorporate analysis that does not rely on bridges for evacuation. Moreover, the geology of the area should be incorporated in the data as a valuable variable that might play a role in the effects of tsunami, through for example liquefaction in the case of clay materials. Moreover, tsnuami are often the results of earthquakes whose impacts are highly related to the geology of the soil. Finally, a road network analysis should be furthered in this project in order to better prepare the stated schools. This is because most of the paths created join together at certain locations, and althrough having already chosen different refuge for each school to avoid crowding at the destination area, crowding on the way there should also play a crucial deciding role.
