An earthquake produces two basic types of waves: surface waves and bulk waves. The former move along the surface of the earth much like the ripples in the surface of a pond, while the other type propagate through the whole earth forming a hemisphere around the point of origin of the quark assuming that it occurred close to the surface.
One particular earthquake produces bulk and surface waves with identical amplitudes at 1 km from the epicentre. What is the ratio of the amplitude of the surface wave to the bulk wave 134 km from the epicentre of the quake assuming that the earth is a perfect, uniform wave medium?
