This is false, as the equator does not run north-south. The equators is the line that goes all around the planet in equal distance from the two poles: so it runs west-east.
It is true however that it runs roughly through the middle of the continent of Africa, but rather on the west-east axis.

Answer:
Surface waves have a longer duration and higher amplitude than body waves.
Explanation:
The stark difference between an earthquake body and surface waves is such that they have longer duration and a higher amplitude compared to body waves.
There are two categories of seismic waves that usually accompanies an earthquake:
- body waves are faster and perpetuate in the subsurface. They reach the seismic station first and are discovered faster.
- surface waves arrives later and they cause the damage produced by most earthquake waves. They perpetuate on the surface.
- surface waves are the love and Rayleigh waves
- body waves are the primary and secondary waves.

The correct answer is - Focus.
Focus of the earthquake, also referred to as hypocenter, is the location/point where the earthquake starts. It is usually few kilometres below the surface. At this spot the ground raptures after which seismic waves start radiating outward in all directions. The focus is located below the epicenter, or rather the epicenter is above it because the location of the epicenter is determined by the location of the focus, so the epicenter represents the closest point on the surface of the Earth from where the focus is.
