Why not all movement along faults produces earthquakes?

Answer:
There are only 4 types (Normal, Reverse, Strike-slip, Oblique-slip) of fault movements that cause earthquake.
Explanation:
There are four main types of faults that produces earthquakes:
- Normal faulting occurs where the crust is being pulled apart.
- Reverse faulting occurs where the crust is being compressed.
- Strike-slip movement occurs when crustal blocks move sideways past each other, usually along nearly-vertical faults.
- An oblique slip comprises numerous groupings of these basic movements.
Faults can be as short as a few meters and as long as 1000 km.
