The impact energy was equivalent to an explosion of roughly 15 tons of TNT
, at least three times higher than the largest previously seen event observed by NASA in March last year.
The vast majority of it was likely vaporized or pulverized to dust when it slammed into the atmosphere and released the kinetic energy equivalent of about 500,000 tons of TNT
, or about 30 times the explosive power of the Hiroshima atomic bomb.
Speeding at some 40,000 mph, it released energy equal to 500,000 tons of TNT
3 meters) in diameter, and traveling about 56,000 mph (90,123 kph) when it slammed into the moon and exploded with the force of five tons of TNT

Fragments of the asteroid caused an explosion equivalent to 500,000 tons of TNT
when they hit.
The Threshold Test Ban Treaty, signed in 1974, banned underground nuclear weapons tests having an explosive force of more than 150 kilotons, the equivalent of 150,000 tons of TNT
, 10 times the force of the Hiroshima bomb.
The explosions engulfed explosive processing facilities with 2 500 metric tons of conventional munitions and 20 tons of TNT
The scientist analyzed data showing the presence of radioisotopes that indicated a uranium bomb had exploded and after a year of work, wrote Nature, "concluded that North Korea carried out two small nuclear tests in April and May 2010 that caused explosions in the range of 50--200 tons of TNT
Helens's eruption in 1980 equaled 20 million tons of TNT
The explosion yields the force of 20,000 tons of TNT
