This paper is focused on the empirical formulations for the estimation of rock mass deformability dependent on data obtained from dynamic methods. The fundaments of dynamic testing, as well as their advantages and limitations, are reviewed. Based on the results of recent studies, a discussion is made on the relationship between dynamic and static deformation moduli, and their dependency on factors such as lithology, weathering, or presence of discontinuity surfaces. The most significant empirical formulations published to this day are summarized, alongside a critical exposition of their characteristics, and a statistical analysis of their results is undertaken. As a result, the influence of the lithology as a crucial factor in the determination of the deformation modulus is highlighted. Thus, it must be properly considered when adopting a formulation for the estimation of the deformability behaviour of a rock mass.
