Earthquakes are caused by shifts in the outer layers of Earth—a region called the lithosphere.
I would say that the US and the Soviet Union at the end of WWII withdrew their troops as soon as a demilitarized zone was created. Also, I am sure they would require a peace treaty to be signed with Germany before withdrawing troops.
C. Nuclear to be honest, I don’t know, but I think this is the answer.
Amount of energy released by the earthquake, and distance from the epicenter. hope that helps!
