  This paper proposes an evaluation method of Regional Safety Factors (RSF) for local voluntary organizations to support their planning and measures for earthquake disaster prevention/mitigation. The RSF is defined as the ratio of the Emergency Response Potential Ability (ERA) to Earthquake Disaster Risk (EDR) of each organization. Against the expected Off Miyagi Earthquake with M_j=7.9, which is one scale larger than the usual assumption model with M_j=7.5, the proposed method is applied to all of the 1,391 organizations in Sendai City. First, based on the evaluated results, variance of earthquake disaster risk over the city-region is clarified. Second, despite higher risks being expected in some organizations, most of their preparedness levels for emergency response were uniformly low. Therefore, a strategy for disaster prevention promotion should be developed considering the spatial risk differences. When a voluntary organization creates a community action plan and/or a local government decides on a performance-based regional planning for earthquake disaster prevention, this proposed method can be expected with long-range monitoring and reassessments depending on the occurrence interval of the target earthquake scenario.
