  There
are other stresses on the lithosphere caused by the very fact that
our Earth rotates on its axis. The equator moves much faster than the
poles. It’s like when a basketball player can balance a spinning ball
on its finger. The player has found the point of the axis that is not
moving and balances it. As you go to the equator of Earth from the
rotational axis you travel from 0 miles per hour to 1000 miles per hour.
On Earth we don’t feel it because of other physical constraints, but
to an "Alien" looking down at us. Well, a polar bear on the
North Pole and penguins on the South Pole would be standing still, while
people in New York would be moving about 600 miles per hour, even if
they were standing still in traffic. So what does this have to do with
earthquakes?
