At least not according to Fundie Preacherman. His latest salvo in the great Heavy Buildings Cause Earthquakes battle:
If you go to back and look at history, I think it was three earth quakes attributed to Hover Dam and two to grand Collie Dam. Not that that would matter to you. I am an Engineer and know and understand the relative mass issues. The more distance from the center of rotation increases the effect on the balance.
Also, in reference to precessional rotation...
That is the center of the ecliptic plane of the earth's rotation about the sun which has a 23 degree inclination to that ecliptic plane. For travel on the ground it is of no issue and the reason the summer is warmer in the southern hemisphere, the earth has it closest approach to the sun. Once you lift off and achieve orbit all navigation is then done with the sun as the reference matrix for calculations. There is a, I think a 23 year cycle, that the earth rotation has small changes. I have never see a theory of why that happens, they just know it happens. It is not a wobble, it is just a difference in rotation axis.
I really should leave this poor old man alone, he's just not quite right anymore, but damn, supposedly he was an engineer -- you'd think he'd actually know about relative mass and precessional rotation. He's probably actually forgotten more than I ever knew about lots of stuff, but the trouble is he doesn't remember what he hasn't forgotten, either.
Your Majesty, I posted your calculations for his perusal, and also your qualifications as a Math Genius (compared to me, anyway). We Shall See...
