For Empirical prediction of strong-ground motion, the attenuation relationship of peak ground velocity is proposed from Japanese strong-motion records. Firstly the strong-motion records observed in Japan are collected and compiled. Using the dataset, the peak amplitudes as well as event and station data are compiled.The functional form of the attenuation relationship is set considering source spectral characteristics, saturation of ground motion intensity in source area, and site effect. The parameters in the relationship are moment magnitude, source distance, and average shear wave velocity of ground. Using about 100 strongmotion records from seven Japanese earthquakes with M of 6.5 to 7.8, the attenuation relationship is developed by the statistical analysis.The relationship proposed is compared with observations during the 1995 Hyougo-ken-nanbu earthquake and other destructive earthquakes. The relationship shows good agreements with the observation, indicating that the relationship proposed would be applicable at close distances.

为了实现强度运动的经验预测，从日本的强度记录中提出了峰值地面速度的衰减关系。首先，在日本观察到的强度记录是收集和编译的。使用数据集，汇总了峰值振幅以及事件和站数据。设置衰减关系的功能形式，考虑源光谱特征，源区域中地面运动强度的饱和度以及现场效应。关系中的参数是地面的力矩幅度，源距离和平均剪切波速度。使用大约100个强度记录，来自七个6.5至7.8的日本地震，通过统计分析开发了衰减关系。提出的关系与1995年Hyougo-ken-ken-nanbu地震和其他破坏性地震进行了比较。该关系显示了与观察结果良好的协议，表明提出的关系将在近距离适用。
