The Ismetpasa segment of the North Anatolian Fault (NAF) is where an aseismic creeping behaviour is observed. As a result, earth scientists are focused on the Ismetpasa segment to understand and explain the nature of creep behaviour. The studies conducted on the segment are based on many different techniques such as simple measuring tape observations, InSAR and GNSS observations, depending on the technological capabilities of the year in which the study is conducted. In this study, GPS (2012–2019) and PS-InSAR (2015–2019) techniques were used to compute and analyse the creep rate in the last decade and compare previous findings. The computed creep rates with GPS and PS-InSAR are about 0.88 ± 0.1 cm/yr and 0.68 ± 0.2 cm/yr, respectively. The creep rates given in previous studies vary between 0.61 ± 0.02 cm/yr and 2.0 ± 0.6 cm/yr. Based on these results, different scenarios in the literature were claimed about the creep behaviour at the Ismetpasa segment. However, none of the studies considered statistical tests to investigate the significance level of the differences between the given results. All the results shared for the Ismetpasa segment are evaluated by statistical significance test for the first time, and the results obtained are discussed. Results indicate that the variety between these studies is insignificant, and the creep rate does not change significantly in long term periods.

土耳其北安纳托利亚断层 Ismetpasa 段长期蠕变行为的统计重新解释

北安纳托利亚断层 (NAF) 的 Ismetpasa 段是观察到抗震蠕变行为的地方。因此,地球科学家专注于 Ismetpasa 部分,以了解和解释蠕变行为的性质。对该段进行的研究基于许多不同的技术,例如简单的卷尺观测、InSAR 和 GNSS 观测,具体取决于进行研究的年份的技术能力。在这项研究中,GPS(2012-2019)和 PS-InSAR(2015-2019)技术被用来计算和分析过去十年的蠕变率,并比较以前的发现。GPS 和 PS-InSAR 计算的蠕变率分别约为 0.88 ± 0.1 cm/yr 和 0.68 ± 0.2 cm/yr。先前研究中给出的蠕变速率在 0.61 ± 0.02 cm/yr 和 2.0 ± 0.6 cm/yr 之间变化。基于这些结果,文献中对 Ismetpasa 段的蠕变行为提出了不同的假设。然而,没有一项研究考虑统计检验来调查给定结果之间差异的显着性水平。Ismetpasa 段共享的所有结果首次通过统计显着性检验进行评估,并对获得的结果进行了讨论。结果表明,这些研究之间的差异是微不足道的,蠕变速率在长期内没有显着变化。Ismetpasa 段共享的所有结果首次通过统计显着性检验进行评估,并对获得的结果进行了讨论。结果表明,这些研究之间的差异是微不足道的,蠕变速率在长期内没有显着变化。Ismetpasa 段共享的所有结果首次通过统计显着性检验进行评估,并对获得的结果进行了讨论。结果表明,这些研究之间的差异是微不足道的,蠕变速率在长期内没有显着变化。
