Most of the people that died in Seoul were party-goers in their 20's. They got crushed to death by overcrowding. At least a third of those that died suffered cardiac arrest. People couldn't breathe because their lungs were being crushed, there was no space to breathe. I'm still surprised just how lethal it can be to be in a press of human bodies. They were pushing from different directions, although it's still unfathomable why the people that were able to move didn't move away when people were screaming and dying. Perhaps because it happened so quickly (death or cause of death within six minutes perhaps) and that the ends of the crowd were so far away that they didn't know what was happening, and just kept pushing.
It's a terrible tragedy, and I didn't know about the freak bridge accident in India too. With so many dead, over 150, plus more injured, questions will definitely get raised. I still can't imagine so many dying in such a way. That's almost as many people that died to global air travel crashes in 2021. The bridge accident is really fishy. It re-opened on 26th October after extensive repairs for 6-7 months, without a safety certificate. The bridge itself was 150 years old.
