Brazil experienced a 6 hour long widespread black out starting at 10:15 Tuesday night, affecting major cities and atleast nine states; nearly half the country.
Power went out for more than two hours in Rio de Janeiro, Sao Paulo and several other major cities, affecting millions of people, after transmission problems knocked one of the world's biggest hydroelectric dams offline. Airport operations were hindered and subways ground to a halt, according to the USA Today.
The 6 hour black out put the country in a state of fear and resulted in a mess of chaos.
Off-duty police were called up as thousands were trapped in immobile elevators and subway trains. Cars were forced to nose through intersections made dangerous by suddenly extinguished traffic lights. Some cafes closed out of fear of a nocturnal crime wave, according to the Assosiated Press.
The cause of the failure had not been determined, but Lobao said strong storms uprooted trees near the Itaipu dam just before it went offline and could be to blame. Rio was the hardest hit city, he said. Huffington Post
The 2016 Olympics are set to be held in Brazil, but this black out may put an apprehension on the decision.
