MAXIMUM PARAMETERS OF GROUND MOTION DERIVED FROM STRONG MOTION DATA IN ALBANIA

Recently, significant efforts were attempted to the re-organization of the former network established in the early 80's. As a result, sixteen digital accelerograph stations were installed most of them concentrated in seismic active, densely populated and industrialized areas. In fact, analog SMA-1 recorders were replaced by digital QDR-s upgrading thus network's effectiveness. A number of accelerograms from small magnitude events have been recorded and data were properly processed in order to obtain the maximum ground motion parameters. Particular importance was devoted to the "band-pass" filter parameters in order to eliminate the noise that influences the spectral characteristics of the signal as well as the absolute values of maximum ground motion parameters in case of strong earthquakes.
