yur too clever....!
Well, I've heard of moonquakes on the Moon, so why not Marsquakes as well? Sounds logical to me...
Dunno, if Mars had bars would they be called Mars Bars?
Nope. They already exist, as of now.<br />
Extra-terrestrial seismic activity. I just made it up but why should that disqualify it as an accepted and useful term?
Nope, that sounds silly. What about we call them chops.
