  abstract = {{W}e propose a new technique to determine the rupture velocity of large strike slip earthquakes. {B}y means of simple numerical ground motion simulations, we show that when the rupture penetrates a shallow layer of sediment or fractured rock, shock waves propagate along the surface fault trace in the forward rupture direction. {S}uch shock waves, which are insensitive to the complexity of slip over the fault plane, propagate at a phase velocity equal to the rupture speed. {W}e show that those shock waves can be easily isolated in the frequency domain, and that phase velocity can then be simply obtained from shear strain.},
