Surface waves will move equally in all directions away from the focus.

Question

Quizplus · Accepted Answer

Surface waves, which are a type of seismic wave, typically move along the Earth's surface and do not emanate equally in all directions from the focus. The focus is the initial point of rupture within the Earth, and while body waves (P-waves and S-waves) emanate outward from this point, surface waves travel along the surface and their propagation is influenced by the Earth's topography and the layers they move through.
