The velocity of rupture propagation is orders of magnitude quicker as opposed to displacement velocity over the fault. Earthquake ruptures ordinarily propagate at velocities which can be within the array 70–ninety% of the S-wave velocity, and this is impartial of earthquake sizing. A little subset of earthquake ruptures show up to have propagated at speeds better compared to S-wave velocity.
