Magnitude determination of near earthquakes for the Albanian network

Analysing about 500 earthquakes recorded by the Albanian Seismological Network during 1984-1988, new relations for the determination of near earthquake magnitudes are found, based on a more accurate correction factor Ao of Richter’ s magnitude formula. The seismological station Tirana was the first to be provided with this a new relationship. Accepting this as the principal formula, others were obtained for different stations of the Albanian network. According to total event signal duration, equivalent relations for the magnitudes were also produced.
