In late years, a variety of basic information has been digitized, studies using Geographic Information Systems (GIS) have been. In this study, using a geographic information system, we performed a correlation analysis by each house and terrain damage in 2007 Mid-Niigata prefecture offshore earthquake and 2004 Mid-Niigata Prefecture Earthquake. The house damage data use the affliction proof by both earthquakes. In addition, that by using the data the whole house, not only analysis of the number of damaged houses traditional, we analyzed the correlation between the rate of affected conversion was calculated to weight the proof afflicted, up one step with the past is also different conduct an analysis, which is one of the features of the present study.
In addition, both near the earthquake occurrence time, which is much the same earthquake magnitude earthquake. Because a disaster area is Niigata Chuetsu area, it is thought that a factor of the earthquake damage has many common points. From this, in this study, we decided to do a comparison from two points of the terrain and distance from the epicenter of the earthquake damage fine comparison of the two.
The earthquake and the degree of impact is high on the distance from the epicenter, the microtopography of each, since a conversion suffering percentage is different, in this study is to build a attenuation, to calculate the distance from the epicenter of classification microtopography each , and build houses of earthquake risk assessment model, was considered comparison with the real damage.
