Seismic wave velocity is mostly dependent on the material they travel through (things like magnitude do not affect wave velocity). As the earth is relatively uniform, there is virtually no deviation in earthquake 'speed'. (Wave velocity will differ depending on phase, depth, etc. - but that's different.)
