In this short paper, the peak ground acceleration estimates of four major Vrancea intermediate-depth earthquakes with moment magnitudes M_W ≥ 6.9 which occurred in the twentieth century are re-assessed using a recently proposed procedure combining macroseismic intensity data with a ground motion model derived for this seismic source. An empirical relation between macroseismic intensity and peak ground acceleration is proposed in this study for Vrancea intermediate-depth earthquakes. The results show that the largest median updated peak ground accelerations are obtained in the case of the Vrancea M_W 7.7 earthquake of November 1940. Moreover, for some cities, the updated peak ground accelerations are higher than the ones given in the current Romanian seismic design code. In addition, peak ground acceleration values in excess of 0.1 g are noticed for almost half of the Romanian territory in the case of the November 1940 and March 1977 Vrancea intermediate-depth seismic events.

在这短暂的纸，四个主要弗朗恰中等深度的地震与矩震级M中的峰值地面加速度估计_W¯¯  ≥6.9发生在二十世纪被重新评估使用最近提出的过程强震强度数据用得到的地面运动模型组合为此地震源。本文针对Vrancea中深度地震提出了宏观地震烈度与峰值地面加速度之间的经验关系。结果表明，在Vrancea M _W的情况下，获得了最大的中值更新峰值地面加速度。1940年11月的7.7级地震。此外，对于某些城市，更新的峰值地面加速度高于当前罗马尼亚的地震设计规范中给出的峰值。此外，在1940年11月和1977年3月的Vrancea中深度地震事件中，罗马尼亚领土的近半数地面加速度峰值超过0.1 g。
