摘要

土耳其位于阿尔卑斯-喜马拉雅地震带。安纳托利亚板块在过去和现在都发生过非常严重的破坏性地震。本研究利用地理信息系统,对 1914 年至 2019 年期间发生在费特希耶-布尔杜尔断层带(一条活跃的断层线)沿线的地震进行了统计分析。对标准距离、标准偏差食、平均中心和中位中心进行了分析,以确定震级值为 3.5 及以上的震中的地理分布。四分法和平均近邻分析用于揭示空间模式。采用安塞林局部莫兰 I 法和 Getis Ord Gi* 法确定地震震中的局部聚集位置。核密度分析用于测量地震震中的密度。四分区分析、平均近邻、全球莫兰 I 指数和 Getis - Ord General G 指数表明,地震聚集在某些区域,并且在位置上相互关联。Anselin Moran's I 区域分析显示,地震高值集中在布尔杜尔市中心西部和叶西罗瓦区,Getis Ord Gi* 方法也得到了类似的结果。

Spatial statistical analysis of earthquakes in the Fethiye - Burdur fault zone

Turkey is located in the Alpine-Himalayan seismic zone. The Anatolian plate has witnessed very severe and destructive earthquakes both in the past and today. In this study, statistical analyses of earthquakes that occurred between 1914 and 2019 along the Fethiye-Burdur fault zone, which is an active line, were conducted using geographic information systems. Analyses of standard distance, standard deviational eclipse, mean center, and median center were conducted to determine the geographic distributions of epicenters with a magnitude value of 3.5 and above. Quadrat and Average Nearest Neighbor analyses were used to reveal the spatial pattern. Anselin Local Moran I and Getis Ord Gi* method were used to determining where the earthquake epicenters are clustered locally. Kernel Density analyses were conducted to measure earthquake epicenters’ density. Quadrat analysis, Average Nearest Neighbor, Global Moran’s I, and Getis - Ord General G indices demonstrated that earthquakes are clustered in certain regions and are related to each other positionally. Anselin Moran’s I regional analyses revealed that high values were clustered in the West of Burdur city center and the district of Yeşilova, and similar results were obtained in the Getis Ord Gi* method.

期刊介绍: Frontiers of Earth Science publishes original, peer-reviewed, theoretical and experimental frontier research papers as well as significant review articles of more general interest to earth scientists. The journal features articles dealing with observations, patterns, processes, and modeling of both innerspheres (including deep crust, mantle, and core) and outerspheres (including atmosphere, hydrosphere, and biosphere) of the earth. Its aim is to promote communication and share knowledge among the international earth science communities
