For Lhe hislorical onrthqtakes, the intensity was thus determined by the uffec_. vnInated accotrding, to the datLa in the sources aind then the magnitude ( I) was calclated; in the case of -nstrumental earthquakes, the satm or tLhe inverse process was followed. For earthquakes for which those values have nLt I e dot ermiied by the autlhrs of the other parameters, the same prot'edure way usied Naturall.', in tlse cas.s it, is not possible to stipulate the quality or the dgree of p~rec'ision of the vilues assigned and therefore the values must b taken with ct't ion; further ovaln tin and homogenization is needed.
