"WebUnlike P waves, S waves cannot travel through the molten outer core of the Earth, and this causes a shadow zone for S waves opposite to their origin. They can still propagate through the solid inner core : when a P wave strikes the boundary of molten and solid cores at an oblique angle, S waves will form and propagate in the solid medium.
