SUMMARYAlbania is a Balkan country with high rate of seismicity, and earthquake risk reduction has been an important, on-going socioeconomic concern. We adapt the experience and methods used for Canadian seismic hazard maps to present, for the first time, probabilistic spectral hazard maps for Albania. A revised catalogue of Albanian earthquakes, from 58 A.D. to 2000, with magnitude Ms>4.5 in the region between 39/N and 43/N and 18.5/E and 21.5/E was used in this study. Ten seismic source zones are used to define the seismicity. We have used the Ambraseys et al. (1996) strong ground motion relations for rock to produce 5% damped spectral acceleration values at 0.2, 0.5, 1.0 and 2.0 seconds (as well as peak ground acceleration) for a return period of 0.0021 per annum (equivalent to a 10% chance of non-exceedence in 50 years). The four spectral parameters maps will allow the construction of site-specific Uniform Hazard Spectra for all of Albania, and are suggested as the basis of the next version of the KTP-N.2-89 Technical Aseismic Regulations to improve earthquake-resistant design code in Albania.
