< p >我一直在做一个小地质研究。One of the topics that I noticed was the existence of "deformations" that appear in the rock layers if an earthquake has occurred. Smaller deformations (on average) imply a smaller earthquake magnitude; larger deformations (on average) imply a larger earthquake magnitude. However, I have not been able to find a mathematical equation saying that a deformation of size X implies an earthquake magnitude of size Y, and vice versa.
Does such an equation exist?
