The relation between Mk and MJ MJ=0.5Mk+4.35 is obtained by the method of least squares, using data from 1926 to 1943. It is shown that the relation can also be applied to earthquakes between 1885-1925. However, for earthquakes before 1885, the relation seems to hold for only large earthquakes with magnitude M(=0.5 Mk+4.85) larger than 8.0. MJ of the great Kanto earthquake of 1923 is given as 7.83 from the seismograms recorded at 3 Japanese stations.
