That is insane, he thought he was at a safe distance and then instantly his life is over. Horrible.

Curious to see what a satellite estimates the blast radius is.
I mean 21 tons of TNT ? Jesus.

Ball park numbers:
1 mole of TNT ~ 250g
1mole of TNT exploding gives ~ 7 moles of gas.
1 mole of gas ~ 22.4 liters
so 250 g of TNT detonating gives ~ 150 liters of gas.
However the gas is not at room temperature (~300 k) but 2000K.
Gas expands ~ 7x when heated from 300 K to 2000 K.
So when 250g (1/4kg) of TNT is detonated, it creates a fireball ~ 1000 liters in size, or 1 cubic meter.
The fireball in the video is ~300m in diameter, or 150m radius.
This means the volume of the fireball is ~14 million cubic meters.
This means ~3000 tons of TNT would be required to make this fireball.
If the estimated diamter of the fireball is reduced to 150m, the volume of course goes down by a factor of 8.
This would still mean an estimated 300 tons would be required.
It certainly seems the chinese estimate of 20 tons of TNT seems on the light side!

The guy that filmed this one is dead. Apparently he was live-streaming through WeChat.
Play the video at .25x speed and you can see the fences and buildings in front of him get torn apart by the shock-wave.
