text: "The Lac-Mégantic rail disaster occurred in the town of Lac-Mégantic, located in the Eastern Townships of the Canadian province of Quebec, at approximately 01:15 EDT,[1][2] on July 6, 2013, when an unattended 74-car freight train carrying Bakken Formation crude oil rolled down a 1.2% grade hill from Nantes and derailed downtown, resulting in the fire and explosion of multiple tank cars. Forty-two people were confirmed dead, with five more missing and presumed dead.[3] More than 30 buildings in the town's centre — roughly half of the downtown area — were destroyed,[2] and all but three of the thirty-nine remaining downtown buildings are to be demolished due to petroleum contamination of the townsite.[4] Initial newspaper reports described a 1-kilometre (0.6 mi) blast radius.[5]"
