“…though the aftershocks, correctly described as the tremblings and groanings, continued for three days (3 Nephi 10:9), during which time the afflicted people carried on in hysterical fashion with frightful howling and lamentation. This too is a normal part of the picture, since ’the incessant recurrence of aftershocks after a great earthquake is most unnerving to the populace.’” (Since Cumorah, p. 235)
