QUANTITATIVE CLASSIFICATION OF EARTHQUAKE WAVE BY PRINCIPAL COMPONENT ANALYSIS
|
´˜^i‰pjF
Although many parameters such as, maximum acceleration and average acceleration level are proposed with regard to earthquake wave, each parameter represents only a part of characteristics of wave. It is then required to catch hold of many characteristics of earthquake wave at the same time and synthetically. If a quantitative evaluation method of earthquake waves is obtained, it may be of great use and become a reasonable standard when selecting the data, and so on. From the above point of view this study discussed how to sum up the parameters of earthquake wave by a few total parameters, and to evaluate quantitatively earthquake waves by the summarized parameters.
