Abstract
The earthquake of May 21, 1961 is investigated. The finally revised epicenter 1.S 34� 36' S. (geographic)., 150� 24' E., and the adopted origin time 21h 40m 01s (G.M.T.). 'The five near stations with a < 1 � . 5 give a PI velocity of 6� 06 � 0 . 17 km/s, and the �eight stations with 2�<;a<;9� give a Pn velocity of S�OO�O�OS km/s. The distribution of the residuals contains no evidence of appreciable focal depth. Using the PI and Pn phases, a crustal thickness (on the assumption of a uniform crust) of 40 � 5 km is formally indicated.
