Y1 - 1989/06// N2 - The maximum likelihood estimation of earthquake hazard parameters (maximum regional magnitude, mmax, earthquake activity rate ?, and b parameter in the Gutenberg-Richter equation) is extended to the case of mixed data containing large historical events and recent complete observations. The method accepts variable quality of complete data in different parts of a catalog with different threshold magnitude values. As an illustration, the procedure is applied for the estimation of seismicity parameters in the area of Calabria and eastern Sicily.
