摘要

在这项研究中,考虑了 1980 年至 2022 年期间土耳其及其周边地区北纬 35-42 度和东经 26-45 度之间发生的震级为 3 级及以上的地震。在这项研究中,土耳其及其周边地区被划分为 114 个单位方格,并以经纬度为圆心,以揭示地震的相似性。研究采用了聚类分析方法,考虑了单位方格内发生的地震在震级和震源深度方面的相似性和不相似性。由于样本数量较多,且分析包括连续变量,因此使用非层次聚类方法将地震数据分为 5 个群组,并观察群组内部和群组之间的关系。

Investigation of Earthquakes in Turkey with Cluster Analysis
In this study, earthquakes with a magnitude of 3 and above between 35-42 North latitudes and 26-45 East longitudes in and around Turkey between 1980 and 2022 were considered. In this study Turkey and its immediate surroundings were divided into 114 unit squares with latitude and longitude circles in order to reveal the similarities in terms of seismicity. It has been applied a cluster analysis by considering the similarities and hence the dissimilarities for the earthquakes occurring in the unit squares in terms of their magnitudes and depths. Since the sample size was high and the analysis included continuous variables, the earthquake data were grouped into 5 clusters using the non-hierarchical clustering method and the relationships within and between the groups were observed.
