Pukkelpop Storm Collapse (Belgium, 2011)

Pukkelpop's sudden storm collapse is a harrowing example of how quickly nature can turn a festival into a death trap. A violent microburst unleashed 90 mph winds, collapsing stages and large tents that killed five people and injured 140, forcing the immediate evacuation of 60,000 attendees. This 30% higher wind speed than the storm that toppled the Sugarland stage rigging demonstrates how even advanced weather monitoring can fail catastrophically. The venue was leveled in under 10 minutes, with debris flying at lethal speeds, making it the deadliest weather-related festival disaster in Europe since 2000.
