Four days before the disaster, residents of the Analco Colonia Atlas district reported a strong gasoline odour from sewers, nausea, and eye irritation. City workers confirmed dangerously high gasoline fume levels in the sewer system, but the mayor declined to order an evacuation, judging there to be no explosion risk.
On April 22, 1992, a series of ten gasoline explosions erupted in the sewer system beneath the downtown district of Guadalajara, Jalisco, Mexico. Over four hours, the blasts and resulting fires destroyed 8 kilometres of streets, with Gante Street sustaining the greatest damage.
The disaster killed an estimated 252 to 1,000 people, left roughly 500 to 600 missing, injured nearly 500, and rendered 15,000 homeless. Monetary damage ranged between $300 million and $3 billion. The affected neighbourhoods are still identifiable today by the modern architecture that replaced destroyed buildings.
