Accelerogram. Comparison with Results in the Northeastern of Spain

Numerical analysis applied to the Beznar dam accelerograms (longitudinal and transversal components) shows that the Fourier amplítude spectrum is a good approxímatíon to the pseudo-velocíty spectra. Thís fact makes possible to use displacement ar velocíty seismograrns to generate acceleration of the ground in places where acceleration data are not avallable. Maximae accelerations determined near and at the Beznar dam are compared wíth the predicted acceleration values far the regían compressed by the Pyrenees Mountains, the lberic System and the Catalonia Coastal Mountains usíng a established theoretical formula far this regían. Theoretical and observad values are consistent among them.
