Does the amplitude of the EMG signal and the force of contraction, as measured by the absolute integrals, increase because a finite number of fibers are firing more often, or because more fibers are recruited to fire as the intensity of signals in the motor neurons increases, or a combination of these two?

Liquefaction was one reason the kobe wharfs were destroyed and other areas nearby. what is liquefaction? a. it is when conditions in the soil send the seismic wave out to the mountains and bounce back b. it is when conditions in the soil change to vigorous p-wave shaking when the surface waves pass by c. it referes to the fact that when an earthquake occurs wet and soft soil will vibrate more vigorously then solid rocky soil strangely in kobe some streets had very bad damage but the next street over had far less damage. what caused this? a. the waves passed through the city hit the mountains and returned back to the city. at some points the incoming and outgoing waves amplified their strength b. the mountains also had a quake and sent waves into the city c. waves hit the moutains and took longer to return
