Ambient seismic field has been used intensively to constrain the Earth’s structure since the early 2000s by extracting impulse response functions (IRFs) between two stations. However, mostly IRF phase information was extracted and used rather than the amplitude. Recently, it was expanded to obtain amplitude information as well as phase, particularly by applying the deconvolution method to the ambient seismic field recorded by broadband seismometers. We investigated the potential of ambient seismic field recorded by accelerometers to extract IRFs, including both phase and amplitude information. We analyzed eight stations widely spaced in South Korea, which also contain co-located accelerometer and broadband velocity seismometer, and demonstrate that the ambient seismic field recorded by accelerometers can be successfully used to extract regional surface waves within the period of 2–10 s. We also investigated the period dependent characteristics of extracted IRFs and found the dominant period band of the secondary microseism recorded in the Korean Peninsula. We expect that the ambient seismic field data recorded by accelerometers can provide much denser IRFs on the Korean Peninsula.

自2000年代初期以来，周围地震场就一直被用来通过提取两个站点之间的脉冲响应函数（IRF）来约束地球的结构。但是，大多数IRF相位信息是被提取和使用的，而不是振幅。最近，它被扩展以获得幅度信息和相位，特别是通过对宽带地震仪记录的环境地震场应用反褶积方法。我们调查了加速度计记录的环境地震场提取IRF的潜力，包括相位和幅度信息。我们分析了在韩国分布较广的8个站，其中还包括同位置的加速度计和宽带速度地震仪，并证明由加速度计记录的环境地震场可以成功地用于提取2-10 s内的区域表面波。我们还研究了提取的IRF的周期相关特征，并发现了朝鲜半岛记录的次生微地震的主导周期带。我们期望加速度计记录的周围地震场数据可以在朝鲜半岛提供更密集的IRF。
