Which seismic waves can travel through liquid medium? - Quora
Answer (1 of 4): Liquids spring back when compressed, but have no strength against shearing. Hence compressional waves, also called P for primary waves, can travel in water, while shear waves, also called S for secondary waves, do not. Love and Rayleigh surface waves also involve shearing, and he...
