Empirical relationships between MSK macroseismic intensity and several engineering ground motion parameters are developed using the macroseismic and instrumental data available for five significant earthquakes (M_w magnitude 6 and above), which occurred during the past half-century in Vrancea region, Romania. The relations are suitable for the Carpathian bend zone and surroundings, and they are valid for intensity values between 5 and 8; in this range, the MSK intensity is basically defined by the level of structural damage. The capability of the selected ground motion parameters to predict the macroseismic intensity is evaluated by observing the standard deviations associated with the proposed regression models. Generally, the parameters which take into account the ground motion duration appear to be more stable predictors than the parameters based on the peak ground motion. The most reliable damage indicator appears to be the Arias intensity. The proposed regression relationships provide intensity predictions with uncertainty close to one-half unit; therefore, they are reliable tools for rapid loss estimation and emergency response coordination following a strong earthquake of Vrancea region. The derived equations represent also useful instruments for seismic risk assessment by methodologies based on macroseismic intensity, since in current practice the earthquake hazard and seismic impact are mainly given in terms of engineering ground motion parameters.

利用可用于五次重大地震（M _w）的宏观地震和仪器数据，建立了MSK宏观地震强度与几个工程地面运动参数之间的经验关系。6级及以上），发生在过去半个世纪的罗马尼亚Vrancea地区。该关系适用于喀尔巴阡弯曲带和周围环境，并且对于5到8之间的强度值有效。在此范围内，MSK强度基本上由结构破坏的程度定义。通过观察与建议的回归模型相关的标准偏差，可以评估所选地面运动参数预测宏观地震强度的能力。通常，考虑到地面运动持续时间的参数似乎比基于峰值地面运动的参数更稳定。最可靠的损坏指标似乎是Arias强度。拟议的回归关系提供强度预测，其不确定性接近二分之一单位。因此，它们是在Vrancea地区强烈地震后进行快速损失估算和应急响应协调的可靠工具。所推导的方程式也代表了基于宏观地震烈度的方法进行地震风险评估的有用工具，因为在当前实践中，地震危险性和地震影响主要是根据工程地震动参数给出的。
