In deep water, a larger-amplitude water wave can be more destructive because wave energy is proportional to the square of wave amplitude ($E \propto A^2$). If the amplitude of a water wave increases from $0.50,\text{m}$ to $1.50,\text{m}$ (with other conditions similar), by what factor does the wave energy increase?

A seismology demo models ground motion as a wave where the energy carried is proportional to the square of the ground displacement amplitude ($E \propto A^2$). If the amplitude of the ground motion is tripled, by what factor does the energy change?
