Koeficijent gamma neelastične atenuacije u Albaniji i korekcije iznosa Ao u Richterovom izrazu za račun magnitude

Using some graphical and analytical methods recommended mostly by American authors, a value of gamma = 0.007052 km-1 is determined for 1 Hz Lg surface waves of near earthquakes of Albania. Starting from this value of g, a reevaluation of the corrections for the Ao factor in the Richter’s magnitude formula for Albania is also carried out. For epicentral distances 80-700 km the difference in magnitude determination between the values obtained using tabulated Richter factor and corrected values is 0.1-0.4.
