Does having more people on the planet affect how often we have Earthquakes? Does this put more pressure on the magma below us all?

Jeez, again more evidence that people have no concept of the size of the Earth.

If I had more space I could show you that the Earth is about 20 TRILLION times the mass of all the people on it. I did the calculation after some other rather uninitelligent person though that if everybody jumped that the same time, they could move the Earth.

20 Trillion - I did not make that up.

There are 6 billion people.

If they average 50 Kgs each, that is 300 billion Kgs

That is only 300 million tonnes.

The Earth is 6 billion trillion tonnes.

It's not a difficult sum.

NOTE also: Ants and termites have more mass than the human race.

One moderate mountain has a thousand times more mass than the human race.

One moderate lake has more mass than the entire human race.

Try and get some perspective.

That is a really good question! I don't think it would actually effect it too much but it is a good thought. Remember that there were trillions of animals, that were bigger than humans, that humans killed off. So that would probably make for less pressure on the crust. One thing that has bothered me is the drilling and emptying of formations of natural gas and crude oil. Also the mining of minerals is putting large voids between the mantle and the surface.

No, the all up weight is the same. These extra people haven't been flown in from another planet. I do know that massive dams can cause seismic activity.

No, you must remember that the mass that makes up all of us and everything that we have built comes from the Earth. So, we are not adding any weight to the Earth. We just using that which is already here.

Yes, especially in countries like the US where everyone is so fat. Tremendous stress on the bedrock.

Well, maybe if all the socialist lefties fell into the deepest geosyncline..............NO.
But I can dream.
Funny thought you had.

Our weight is so minimal, that the answer has to be no.
