Disasters at Mass Gatherings: Lessons from History[1]
Summary
A companion review of mass-gathering crowd disasters (excluding weather/environmental causes) found 156 events from 1971–2011, of which only 21 appeared in peer-reviewed literature (12 case reports, five review articles, four commissioned inquiries). Cases were analyzed across crowd control, event access, fire safety, medical preparedness, and emergency response, concluding that a mix of high crowd density, restricted access points, poor fire safety, minimal crowd control, and lack of onsite medical care can produce disaster.
So what
Names the recurring structural precursors of crowd disasters — density, restricted egress, fire-safety and crowd-control failures, and absent onsite medical care — as a checklist of what venue planning must actively prevent.
Key findings
- 156 crowd disasters identified (1971–2011); only 21 in peer-reviewed literature.
- Analyzed across crowd control, access, fire safety, medical preparedness, response.
- High density + restricted access + poor fire safety + weak crowd control + no onsite care → disaster.
