A series of ten explosions took place on April 22, 1992, in the downtown district of Analco Colonia Atlas in Guadalajara city, Jalisco state, Mexico. Numerous gasoline explosions in the sewer system and fires over four hours destroyed 8 kilometres (5.0 mi) of streets. Gante Street was the most damaged. By the accounting of Lloyd's of London, the reported number of people killed was about 252 people although many estimate that the catastrophe actually caused at least 1,000 deaths. About 500 to 600 people were missing, nearly 500 were injured and 15,000 were left homeless. The estimated monetary damage ranges between $300 million and $3 billion. The affected areas can be recognized by the more modern architecture in the areas that were destroyed.Four days before the explosion, residents started complaining of a strong gas-like smell coming from the sewers which became progressively more pungent over the course of those days. They were experiencing symptoms such as stinging in their eyes and throats; and nausea. Some residents even found gasoline coming out of their water pipes. City workers were dispatched to check the sewers and found dangerously high levels of gasoline fumes. However, the city mayor did not feel it was necessary to evacuate the city because he felt that there was no risk of an explosion.
