In the southernmost part of the Arabian Shield, southeastern onshore of the Red Sea, damage earthquakes were historically reported implying that the region may be susceptible to have a potential seismic hazard in future. To understand the potential seismic hazard in the region, we present an analysis to simulate the peak ground accelerations (PGA) from future large earthquakes of Mw 6.0, and 6.5 in the region using an empirical Green's function (EGF) summation technique. The waveform recordings for a small-sized earthquake of Mw 4.4, that occurred in 23rd of January 2014, were used as an element earthquake. The estimated PGA values are consistent with the corresponding values of ground motion prediction equations (GMPEs) that derived for California, Japan, and Western Saudi Arabia, indicating that these equations are applicable for rock site conditions in the region. The results of response spectra reveal periods vary from 0.2 s to 3.0 s, implying potential hazard impacts for short and tall buildings.

在红海东南岸的阿拉伯地盾最南端，历史上曾报道过破坏性地震，这意味着该地区未来可能容易发生潜在的地震灾害。为了了解该地区的潜在地震危险，我们进行了一项分析，以使用经验格林函数 (EGF) 求和技术来模拟该地区未来 Mw 6.0 和 6.5 大地震的峰值地面加速度 (PGA)。2014 年 1 月 23 日发生的 4.4 级小地震的波形记录被用作单元地震。估计的 PGA 值与为加利福尼亚、日本和沙特阿拉伯西部导出的地面运动预测方程 (GMPE) 的相应值一致，表明这些方程适用于该地区的岩石现场条件。响应谱的结果显示周期从 0.2 秒到 3.0 秒不等，这意味着对矮和高建筑物的潜在危害影响。
