RFS 2001-01 replaced RFS I.2.c, published in 1981, however it has been criticised for continuing to require a deterministic assessment (rather than a probabilistic approach) that relies primarily on the strongest 'historically known' earthquake near a site.
《RFS 2001-01》取代了1981年发布的《RFS I.2.c》，但是它一直受到批评，因为它继续需要一个确定性评估（而不是概率风险评估方法（英语：Probabilistic risk assessment）），主要依赖于站区附近最强的“历史上已知的”地震。
