Detailed breakdown of key historical incidents
One woman tripped on a dark staircase. 173 people died - because nobody behind could see why the crowd had stopped.
A last-minute goal sent fans surging back up the exit stairs - straight into the people still leaving.
Thousands waited outside. Only a couple of doors opened. The crowd mistook the soundcheck for the show.
A flimsy fence, a crumbling wall, and rival fans in the wrong place - a disaster built before kickoff.
To relieve a crush outside, an exit gate was opened - funnelling thousands into pens that were already full.
Rain, mud, and a surge toward the stage. Nine young men suffocated in the crowd at the front.
Crowd crushes kill by compressive asphyxia — not trampling. It comes down to density.
