The amount of energy the killer tornado that hit US state of Oklahoma had dwarfed the power of the atomic bomb that levelled Hiroshima.
On Tuesday, the National Weather Service gave it the top-of-the-scale rating of EF-5 for wind speed and breadth and severity of damage. Wind speeds were estimated at between 200 and 210 mph.
According to the New York Post, several meteorologists used real time measurements to calculate the energy released during the storm's life span of almost an hour.
Their estimates ranged from 8 times to more than 600 times the power of the Hiroshima bomb with more experts at the high end.
The tornado at some points was 1.3 miles wide, and its path went on for 17 miles and 40 minutes.
The hot spot is more than just the city of Moore. Several meteorologists said that it was 'bad luck' why that suburb seemed to be hit repeatedly by violent tornadoes.
