There is no difference. The definition of fault is precisely: a crack in the Earth's crust.
Crust
Vulcanicity is a process through which gaseous, liquid and solid materials are forced out of the earths crust to the earths surface. Volcanicity is the process where igneous materials reaches the earths surface from the earths crust to the earth surface
Fault mountains are formed when rocks crack down due to lines of weakness in the earths crust. This cause huge blocks to move forming block mountains. Fold mountains are formed when land is folded into wave like shapes because of the tectonic movements underneath the earth crust.
Cracks in the Earth's crust are called faults. They are typically a result of the action of tectonic forces and may be the cause of earthquakes.
The earths crust is a part of the outermost layer.

A fault.
A mega earthquake is seismic activity below the earths crust that causes fluctuations in the earths tectonic plates. This forces the ground to shake and the earths crust to crack.
