Topographic amplification means that shaking tends to be stronger
Answer: B
Correct answer: at ridge crests than at the base of a slope
Waves arriving at a ridge are focused by its geometry and are reflected within it, so the crest shakes more strongly than the surrounding ground - sometimes by a factor of two or more. The effect is well documented in post-earthquake damage surveys, where structures on ridge lines fare noticeably worse than identical ones on the flat.
