Abstract : Amplification of the Eaton method for the determination of the seismometer damping, to make it more easily applicable in cases of large periods or dampings. A graph is presented which makes it possible to determine the damping as a function of the time which delays the initial elongation (release test), or maximum one (tapping test), of the recorded response curve in decreasing to a certain fraction, Q, of its value.
