Popis: In this paper, the immediate estimation system for wide-area distribution of seismic intensity by using seismic intensity information network system is discussed. In general, although seismic intensity on each seismic intensity monitoring points can be obtained by using seismic intensity information network system within a few minutes after earthquake occurs, wide area distribution of seismic intensity is not obtained. This is because the number of seismic intensity monitoring points on the network system are very few and limited to estimate distribution of seismic intensity. However, by using other information, such as soil profiles on the ground of local areas and attenuation characteristics of seismic intensity, distribution of seismic intensity can be estimated with computer simulation considering seismic wave amplification on the ground immediately after seismic intensity information form the network system is obtained. Especially, array density and optimum arrangement of seismic intensity monitoring...
