The active tectonics of the Gulf of Aqaba (Red Sea) may affect the newly established NEOM megacity in northwestern Saudi Arabia. Using seismological and potential field data, this study aimed to evaluate the major tectonic trends around NEOM area and their hazard impacts on the NEOM area. In particular, aeromagnetic and gravity data were used to explore the major tectonic trends that may affect this area. The interpreted tectonic trends are directed mainly along the NNE and NNW, as well as NW and EW tectonic trends. A good correlation was found between the distribution of the earthquake epicenters (M_w ≥ 4) and the interpreted tectonic trends. Moreover, the distribution of epicenters was congruent with the fault trends obtained from the potential field data, implying that the observed fault trends can generate earthquakes. For the seismic hazard assessment, the source parameters and expected ground motions of two moderate earthquakes that occurred in the Gulf of Aqaba in 2015 and 2016 were analyzed. Assuming an omega-squared source model, a grid search method was applied to fit the amplitude spectra of the S-wave group over the model parameters that were used to compute M_o values of 4.06E + 23 and 2.14E + 23 Nm, corresponding to M_w of 5.0 and 4.8, fault radii of 831 m and 835 m, and stress drop (Δσ) values of 7.72 and 4.01 MPa for the 2015 and 2016 earthquakes, respectively. An empirical Green’s function summation technique was performed to simulate high-frequency ground motions expected for future large earthquakes, demonstrating the influence of such earthquakes on the study area. For a Δσ value of 10 Mpa (characteristic of past earthquakes in the Gulf of Aqaba), peak ground accelerations of ∼ 5.6 and 5.53 m/s² are to be expected for future earthquakes with Mw 7.0 in the epicentral regions of the 2015 and 2016 earthquakes.

亚喀巴湾（红海）的活跃构造可能会影响沙特阿拉伯西北部新建立的NEOM大城市。本研究使用地震学和潜在的现场数据，旨在评估NEOM地区周围的主要构造趋势及其对NEOM地区的危害影响。特别是，利用航磁和重力数据来探索可能影响该地区的主要构造趋势。解释的构造趋势主要是沿着NNE和NNW以及NW和EW构造趋势。发现地震震中的分布（M _w≥4）和解释的构造趋势。此外，震中的分布与从潜在的野外数据获得的断层趋势一致，这意味着观测到的断层趋势会引发地震。为了进行地震危险性评估，分析了2015年和2016年在亚喀巴湾发生的两次中等地震的震源参数和预期的地震动。假设欧米茄平方源模型，则应用网格搜索方法将S波组的振幅谱拟合到用于计算M _o值为4.06E + 23和2.14E + 23 Nm的模型参数上，对应至M _w2015年和2016年地震的断层半径分别为5.0和4.8，断层半径分别为831 m和835 m，应力降（Δσ）值为7.72和4.01 MPa。进行了经验格林函数求和技术，以模拟未来大地震可能发生的高频地震动，证明了此类地震对研究区域的影响。对于Δσ值为10 Mpa（亚喀巴湾以往地震的特征），对于2015年和2016年震中地区7.0 Mw的未来地震，预计地面加速度峰值约为5.6和5.53 m / s ^2。地震。
