SEISMIC HAZARD ESTIMATION FROM BACKGROUND SEISMICITY USING CUBIC LATTICE PARTITION
|

| 抄録（英）： |
Many seismic hazard studies estimate the seismic hazard by area from background seismicity by first dividing the region into several earthquake areas according to the structure of seismic zones and some other factors in such a way as to make all the areas have earthquakes almost equal in scale and similar hypocentral mechanisms. However, establishing such earthquake areas demands a detailed seismological study of the region and poses the following problem: there is an unavoidable effect produced by the method of dividing up areas for seismic hazard estimation from background seismicity. In this paper, we propose a method to estimate seismic hazards according to background seismicity by using a cubic lattice partition model; this model does not depend on the establishment of earthquake areas. Furthermore, to clarify the effect of the cubic lattice partition size on the estimation of seismic hazard, we calculated the seismic hazard for various partition sizes.
