Based on the idea that indoor space safety ought to be improved in addition to earthquake-resistant construction of dwellings to reduce casualties by earthquakes, we have been developed diagnostic methods aimed at indoor risk reduction system. In succession from the previous paper that one of us proposed the indoor-zoning method for seismic injury risk potential caused by furniture overturned during shaking, we developed the refuge route network method of evaluating evacuation risk to outdoors immediately after seismic motions end. Our method can quantitatively analyze injury risk for evacuation route by the introduction of new indices as an refuge distance to out-doors, difficulty of passing through the evacuation routes, and inhabitant's walking speed dependent on age, sex, and morbidity.
