“The Book of Mormon also mentions the rising and sinking of the land, forming new ‘hills and valleys’ (3 Nephi 9:5-8)…Hydrographic surveys after the Japanese quake of 1923 showed that over an area of 500 square miles some ’areas were … lowered as much as 689 feet and other … areas raised 820 feet’—a difference of over 1,500 feet.’” (Since Cumorah, p. 236)

“…they used to tell us that the Rocky Mountains and the Andes were the results of this earthquake. Would you believe anything like that? Utter nonsense, isn’t it. These mountains out here weren’t formed in that way, were they? What does this describe? It describes a good earthquake, maybe 8.5 on the Richter Scale.” (Teachings From the Book of Mormon, Lecture 89, p. 38)
