6. [Initial letter of secondary.] Used, chiefly in S wave, to denote an earthquake wave which oscillates transversely to the direction of propagation, a shear wave; so named because secondary waves arrive at a given place later than primary waves. (See also P wave at P n. 6.)

1913 G. W. Walker Mod. Seismol. vi. 39 A pronounced movement corresponding to the arrival of the longitudinal disturbance, and..a pronounced movement when the transversal disturbance arrives, both of which have travelled by the brachisto~chronic path... These are..identified with the beginning of the first phase P and the second phase S of a seismogram.
