The selection of ground‐motion prediction equations (GMPEs) to perform seismic hazard assessments is challenging for stable continental regions that lack a sufficient number of recordings. In this study, we implement various ranking methods to test the efficiencies of a wide range of GMPEs against the recordings from three of the largest magnitude inland earthquakes that occurred in the Korean Peninsula, which belongs to an intraplate region with low seismicity. In this context, we select a total of 14 GMPEs developed for active shallow crustal zones (Next Generation Attenuation‐West2 [NGA‐West2] project), stable continental regions, and Korea. Three statistical approaches, including the classical residual, log‐likelihood (LLH), and Euclidean distance‐based ranking (EDR) methods, are used to evaluate the performance of the GMPEs. The residual analyses show that for the very short spectral period (⁠T≤0.1 s⁠), regionally developed GMPEs perform the best, whereas the NGA‐West2 GMPEs outperform other equations for short (⁠0.2≤T≤0.5 s⁠) and medium to long periods (⁠T≥0.75 s⁠). The LLH approach is shown to favor a stable continental region GMPE that has the highest standard deviation. The EDR method, which can account for both aleatory uncertainties and model bias, is found to favor the NGA‐West2 and Korean GMPEs. NGA‐West2 GMPEs show the lowest model bias, whereas the Korean GMPEs exhibit the lowest residual bias. Five GMPEs selected based on the EDR method are recommended for a probabilistic seismic hazard analysis in Korea. For deterministic hazard assessment, using the Korean GMPEs for the very short spectral period and NGA‐West2 GMPEs for short and medium to long periods is recommended. Overall, the stable continental region GMPEs are demonstrated to perform poorly when tested against the earthquakes recorded in Korea.

针对韩国记录的中度地震数据测试地震动预测方程

对于缺乏足够记录数量的稳定大陆地区而言，选择用于进行地震危险性评估的地震动预测方程式（GMPEs）具有挑战性。在这项研究中，我们采用各种排序方法来测试各种GMPE的效率与朝鲜半岛发生的三起最大内陆地震（属于低地震板内区域）的记录之间的关系。在这种情况下，我们总共选择了14个GMPE，分别用于活跃的浅地壳区（Next Generation Attenuation-West2 [NGA-West2]项目），稳定的大陆地区和韩国。三种统计方法，包括经典残差，对数似然法（LLH）和基于欧氏距离的排名（EDR）方法，用于评估GMPE的性能。残差分析表明，在非常短的频谱周期内（⁠T≤0.1s⁠），区域开发的GMPE表现最佳，而NGA-West2 GMPE在短时间内（⁠0.2≤T≤0.5s⁠）和中等方程的性能优于其他方程。长时间（⁠T≥0.75s⁠）。LLH方法显示出偏向于具有最高标准偏差的稳定大陆区域GMPE。发现EDR方法可同时解决不确定性和模型偏差，被认为有利于NGA-West2和韩国GMPE。NGA-West2 GMPE显示出最低的模型偏差，而韩国GMPE显示出最低的残余偏差。在韩国，建议采用五种基于EDR方法的GMPE进行概率地震灾害分析。为了进行确定性危害评估，建议在很短的频谱周期内使用韩国的GMPE，在短，中，长周期内使用NGA-West2 GMPE。总体而言，在针对韩国记录的地震进行测试时，稳定的大陆地区GMPE被证明表现不佳。
