Columbian Chemicals Plant explosion hoax

The Columbian Chemicals plant explosion was a hoax claiming an explosion at a chemical plant in Centerville, St. Mary Parish, Louisiana. On September 11, 2014, reports of an alleged explosion were sent to local residents via text messages and spread through various social media. Several reports claimed that the militant group ISIS had taken responsibility for the attack. St. Mary Parish officials claimed that the reports of an explosion were a hoax. A spokesperson for the company told reporters that the reports of an explosion were a hoax:

"We have been informed by the community that a text message has been received by several individuals indicating a release of toxic gas from the Birla Carbon's Columbian Chemicals Plant near Centerville, Louisiana. The content as stated by the text message is not true. There has been no release of such toxic gas, explosion or any other incident in our facility. We are not aware of the origin of this text message. Law enforcement authorities have been contacted and are following up on this matter."

Betaworks CEO John Borthwick described the hoax in an essay as an unsuccessful attempt to "hack" social media. The essay uses analysis by Betaworks data scientist Gilad Lotan to argue that the effort likely originated inside Russia, and failed to achieve virality in part because the fake identities it used had little connection with genuine human identities. Borthwick concludes that a successful hoax would have required its creator to embed the fake identities in real social networks, which he argues would have required considerable time and effort.[2]

In June 2015, the New York Times Magazine published an extensive article by Adrian Chen, claiming the hoax "was a highly coordinated disinformation campaign" and that the "virtual assault" was the work of the Internet Research Agency, a Russian institution specialized on nationalistic online propaganda, funded either by the Russian Government or a close ally.[8] According to Chen, this was "one in a wave of similar attacks" in 2014 using similar techniques and included the Ebola hoax in Atlanta.
