It may be difficult to reduce the earthquake disaster such as human losses and building collapse to zero in the severe strong ground motion. The most important thing in the prevention of the earthquake disaster is to reduce the seismic damage to the slightest level which does not yield extreme social impact and is easy to restore the damage. The social response can be estimated by the amount of report about seismic damage in the newspaper. The report ratio of seismic damage to total report in newspapers is surveyed for 30 days after the event for the earthquakes which yield heavy disaster from 1946 to 1995. The report ratio decreases with day after earthquake and it can be approximated by the exponential function. The slightest level of seismic damage is estimated using the relation of the magnitude of report ratio or the continuance of the report ratio and the total seismic damage which is defined as the function of the number of human losses and collapsed buildings.
