Now i don't know if this is just a stupid question :) But i came to thinking while reading the news about the Earth having slowed down 3microseconds because of the recent earthquake in souteast asia. The explanation i read was that it was because the Earth's crust had moved a few meters up and so the moment of inertia of the Earth had been changed.
This got me to thinking, that this is no different then building a house (obviously on a much smaller scale), and was wondering if there was any way to calculate the Earth's moment of inertia if there were no houses on the Earth at all, so all bricks/cement/metal used in houses were not raised above the Earth in houses, but still in the ground where they were originally harvested.
Is there any way to do this relatively easily? That is without just crunching it the hard way on paper I'm bad enough with just "normal" simple shapes
