Russia's 'father of all bombs' is 4 times stronger than the 'mother of all bombs' for a horrifying reason

[SZonian]

On April 13, the US military dropped a school bus-size munition nicknamed the "mother of all bombs" on a network of ISIS-held caves and bunkers in northeastern Afghanistan, according to the Pentagon.

Weighing about 21,600 pounds and stretching 30 feet, each MOAB (officially called the GBU-43/B Massive Ordnance Air Blast) can explode with the power of about 11 tons' worth of TNT, making it the largest conventional bomb in the US arsenal.
 
However, MOABs are not the most powerful non-nuclear explosives in the world.

That title belongs to the Russian-built "father of all bombs," also called "Blackjack" by NATO.

Each FOAB can detonate with the power of 44 tons' worth of TNT, or with four times the MOAB's yield. (This is more than 1,000 times weaker than the first atomic bomb detonations.)

But these gigantic bombs are two entirely different beasts designed to kill enemies in different situations.

This is a little bit misleading.  Yes, a fuel air explosive bomb incinerates.  But it is really the blast wave it generates that is the point of using that weapon, as the "incineration radius" is much smaller than the fatal blast/overpressure radius, followed by the vacuum pressure.  It's not really analogous at all to napalm or WWII fire-bombing raids, where it is the fire itself that does the damage.
