In this paper the accuracy of routine methods for processing strong-motion earthquake accelerograms (Trifunac, 1971, 1972; Hudson et al., 1971) has been tested by comparing displacement curves computed from the twice-integrated accelerograph recordings with displacement curves computed from displacement-meter measurements. The displacement meters have transducers with natural periods typically several seconds long. Agreement is found to be very good, suggesting that the methods used for routine processing of strong-motion accelerograms are quite accurate.
