Caribbean Petroleum Corp. Refinery – Bayamon, Puerto Rico 2009
Due to a faulty gauge, refinery workers did not notice that an overfilled fuel tank was emitting deadly vapor. The fumes caught fire, causing an explosion equivalent to a 2.8-magnitude earthquake. The flames spread to fuel containers, raging for 66 hours until there was no more material left to burn. The catastrophe destroyed 20 tanks, damaged another 12, and battered hundreds of homes and businesses in a 2km radius. The Fort Buchanan military facility suffered over USD 5 million in damages. In addition, 136 million liters of petroleum were released into the environment. The Caribbean Petroleum Corporation, facing an estimated USD 200 million in damages, filed for bankruptcy in 2010.
