[MIS17-P06] Multiscale Analysis of Earthquake Damage Factors
★Invited Papers
Keywords:Earthquake disaster, Multiscale analysis, Damage factor
The factors that cause various damages due to earthquakes include not only seismic motion and natural factors, but also human and social factors, and these interact in complex ways to cause damage. In order to correctly understand the structure of such damage occurrence, it is necessary to properly organize each factor, taking into account the differences in spatial scale and impact, rather than sticking to specific factors or listing factors.
In this study, we attempted to capture the regional characteristics behind earthquake damage and its background from a geographical perspective using multi-scale analysis. Based on this, we tried to effectively organize the complex and layered factors of damage by creating a model of the damage occurrence structure.
We conducted a factor analysis using multi-scale analysis on the damage of three inland earthquakes in the modern and early modern periods. Based on these results, we succeeded in conceptualizing the overall picture of the complex and layered relationship between disaster inducement and inherent factors for the occurrence mechanism of building collapse damage and human damage. This made it possible to organize and explain the factors of earthquake damage, 1) the difference in scale and impact of each factor, 2) the distinction of the nature of the factors, 3) the positioning of each of the multiple existing factors, 4) the layered nature and mutual relationship of the factors.
By creating a conceptual diagram, it became possible to visualize and understand the structure of damage occurrence, and it became easy to compare the structure of damage occurrence even in different ages and regional damage cases.
