Astroworld Crowd Crush (Houston, 2021)

Astroworld’s crowd crush remains the deadliest U.S. concert security failure of the past two decades, with 10 fatalities and hundreds injured despite clear distress signals from attendees. Investigations found medical staff levels were 60% below recommended guidelines for an event of 50,000 people, and security ignored 93% of reported crowd-compression incidents in the hour before the surge. This failure ranks third-worst in historical casualty speed among event disasters.
