摘要

本文利用地震资料和极大似然方法，介绍了印度尼西亚东努沙登加拉省地震的空间分布、时间构造和重现期。使用的数据是ISC、USGS/NEIC和印度尼西亚气象、气候和地球物理局（IMCGA）1918年至2015年期间的地震目录数据。结果表明，a值在5.0到8.5之间，b值在0.6到1.3之间。b值的空间分布模式相对较低，对应于a值的较低，这意味着该地区岩石的应力水平较高。分形维数表明，D值在1.384到1.874之间。发生在东努沙登加拉省的地震以小震级为主，地震活动性强，最快的重现期是阿洛尔岛和帝汶岛，为44天。

Correlation Analysis of Spatial Distribution, Temporal Seismotectonics, and Return Period of Earthquake in East Nusa Tenggara, Indonesia

This paper presents spatial distribution, temporal seismotectonics, and return period of earthquake in East Nusa Tenggara Province, Indonesia, using earthquake data and Maximum Likelihood methods. The data used are ISC, USGS/NEIC, and Indonesian Meteorology, Climatology and Geophysics Agency (IMCGA) earthquake catalog data for the period of 1918 to 2015. The results show that the a-value ranges from 5.0 to 8.5 and b-value ranges from 0.6 to 1.3. The pattern of spatial distribution of b-value is relatively low corresponding to the low of a-value, which means the high level of stress of rock in the area. The fractal dimension shows that the D value ranges from 1.384 to 1.874. The earthquake that occurred in East Nusa Tenggara Province was dominated by a small magnitude with great seismicity and the fastest return period is in Alor and Timor islands which is 44 days.
