| Research Abstract |
Near field earthquakes bring catastrophic disasters in large urbanized cities. Local governments must prepare the regional mitigation plans on the basis of seismic hazard and risk estimation in order to protect the building environment and the population. In case of Sapporo City, that is our research target, it is difficult to specify the source parameters of near field earthquakes affected the populated area. It is necessary to investigate the influence of indefinite parameters upon the risk assessment.
In this paper, we enforced an importance of the plural estimation of seismic damages by probable earthquakes occurring near the urban area. Paying attention to the difficulties of taking measures against all of the cases on estimated damages, we gave an example of the rule of making decision about the priority of mitigation plans from the point of view of earthquake engineering and political science. Finally, we applied the Analytical Hierarchical Approach proposed by T.L.Saaty to decision-making on priority measures for earthquake prevention planning.
