Have all the natural occureences i.e; earthquakes, tsunamis, volcanic activity, even the separation of the Continents ever expanded or contracted the Circumfrence of teh earth at the Equator?

Over billions of years and to this day, the earth has been increasing in mass due to the impact of meteors and comets. It seems likely that this has caused the earth's circumference to increase. The activity you mention in your question can move parts of the earth around but I would not think it would change the circumference significantly or measurably.

In addition to what ebk1974 said, it present theory of how the moon formed is that when the earth was molten or near molton about 3.9 billion years ago, it was struck by a huge body and the moon popped out from the other side. This would have reduced the circumference of the earth a lot. The other things you listed would not have any real effect on the circumberence of the earth.

Yes, the earth is constantly in flux, but, no, as it is just about the same size as ever. The planet is not a perfect sphere, it's short, as the middle, (around the equater) is wider then it's height, Kinda like it was smashed down a little. This is because it's spinning, and there is a moon, and a sun pulling there. So depending on the outside forces, it changes constantly.

The earth cannot get smaller. It's made of solids and liquids which cannot squeeze tighter to become smaller than they are; however, many tons of space dust fall into the earth's atmosphere every day so I suppose over a very long time frame the earth is actually growing and therefore expanding.

The circumference of the earth is constantly changing. The earth is still accumulating space matter.

The speed of the planets rotation has changed and that would effect the diameter at the equator. The faster it spins the more the planet would bulge at the equator.

It deppends on the precision of the measurement and on the time period taken in consideration, but as everything in universe is in dynamic equilibrium it is not likely that the circumference has remained constant.

I hear it gets a little wider around the holidays ;)
