The epicentre of an earthquake refers to the point on the Earth`s surface directly above the seismic focus. Option 1 is incorrect because the earthquake originates at the seismic focus, which is located beneath the Earth`s surface, not at the epicentre. Option 2 is incorrect because being prone to volcanoes is unrelated to the epicentre of an earthquake. Option 3 is incorrect because the intensity of seismic waves does not decline from the epicentre. In fact, the intensity is usually highest at the epicentre and decreases as you move further away. Therefore, option 4 is the correct answer, as it accurately describes the location of the epicentre relative to the earthquake`s focus.
