The two explosions at Silo 110 of the plant formed a crater 90 m by 125 m wide and 19 m deep. The explosions were heard as two loud bangs in north-eastern France and in München, more than 300 km away, and are estimated to have contained an energy of 1–2 kilotonnes TNT equivalent. Over 2.000 people were injured. According to some descriptions only 10% of the 4.500 tonnes of fertilizer stored in the silo detonated in the incident.
