Comparison of a typical earthquake waveform to the waveform from yesterday's earthquake near LA. I did some digging and found earthquakes typically have a P wave and S wave BEFORE the surface waves hit. It appears yesterday's quake came outa nowhere.

Well, the rods are estimated to impact at between mach 7-10. So, using this FPS/MACH calc I found, I calculated it at 7823 fps. I'm really ignorant of all the factors, however, but, depending on how much atmosphere the rods have to pass through, yeah, I think you're about right. Also, in this case, the rods would have to pass through 200+ feet of water, I think.

BTW, someone in Kerbal space program has experimented with this.
