There have been lots of crowd crushes in the last 200 years, and the number is increasing. They seem to become more common all the time.
But what actually causes them? How can people walking into the back of other people actually cause fatalities?
I underatand that people can be compressed enough to be unable to breath, but what possesses the people at the back of the crowd to keep pushing forward even when the crowd stops moving?

Once you surpass a critical density of 7-8 people per square meter, individual movement becomes impossible. The crowd begins to behave like a fluid. Individual people collapsing can lead to propagating "waves" in the crowd, creating temporary areas of higher and lower density.
This gives the people at the back the illusion that they are moving forward. At the same time they have no clue what's happening at the front of the crush.

It's funny how you can know they're Peruvians just by looking at their faces.

Because pushing people with your body weight will seriously hurt sombody
Now imagine that push being multiplied by 200x
That results in alot of dead and crush people
Also panic is the biggest driving force, either fire or anything scary will result in a panic
Here is a very good analysis of aspects of a crowd crush
