and you’ve written how many papers on supershears?
Wikipedia is (uncharacteristically for engineering/science) not very talkative. All it says is that the rupture propagation speed exceeds the S-wave velocity, creating an analogy to a sonic boom.
So does that imply one has a propagating "shock wave" ? Which confuses me, what are the relevant state variables for the ground, which would suffer a discontinuity -- and how would the "shock" differ from the ordinary S and P waves?
Color me overdosed on chocolate bunny ears too.
