为了重新评估核电站(NPP)CerNavoda的地震危险性，对Vrancea中等深度震源向东南方向的特定衰减进行了详细修订。为此，我们考虑了该地区现有的所有强震数据，并测试了各种关系类型。由于仪器数据受震级和深度间隔的限制，根据这些数据推导出的衰减规律外推到大震级是非常不稳定的，必须仔细考虑。在现有数据库的特征域外进行外推会导致很大的偏差，特别是在大震级和以深度为独立参数的关系上。
Attenuation specific from Vrancea intermediate-depth focus toward SE is revised at length in order to re-evaluate the seismic hazard at the nuclear power plant (NPP) Cernavoda. To this aim, we took into consideration all the strong motion data available for the region and test a large range of relationship types. Since the instrumental data are limited as magnitude and depth intervals, the extrapolation based on the attenuation laws deduced from these data to great magnitudes is very instable and must be carefully considered. The extrapolation outside the characteristic domain of the available database leads to large deviations, especially at large magnitudes and for the relations which contain the depth as independent parameter.
