The connection between seismic moment and a torque is natural in the body-force equivalent representation of seismic sources as a double-couple (a pair of force couples with opposite torques): the seismic moment is the torque of each of the two couples. Despite having the same dimensions as energy, seismic moment is not a measure of energy.
Writing in response to institutional arguments, Diamond agreed that institutions are an important cause, but argued that their development is often heavily influenced by geography, such as the clear regional pattern in Africa where the northern and southern countries are wealthier than those in the tropical regions.
