Incendiary Effects of Explosions?

[Flashlight237]

So I recently came across this calc by @StrymULTRA : https://vsbattles.fandom.com/wiki/User_blog:StrymULTRA/Undertale:_Undyne's_house_explodes_(RECALC)

This made me realize something... We never really covered the incendiary effects of explosions, did we? I mean the destruction here is basically just crap burning and a fish lady getting scorched. The problem here is neither Wikipedia, the Nuclear Secrecy blog, nor Antoniofer's blog (linked in the calc) have incendiary effects listed anywhere on their overpressure charts. Is there any resource listing the incendiary effects of explosions?

Best I can think of is the nuke thing listing fireball radius. It also has parts on thermal radiation.

I know it is a little late but that also got me curious as there is this link below on the percentage of what goes into the energy output of a nuke.

What I have seen is that non nuke calcs here are usually divided by like 50%, but shouldn’t it be multiply by 85% since 15% is the amount of radiation? And the other 85% is thermal? I would say you can do 50% if there is without a doubt no thermal affect in the explosion right?

50% is shockwave, 35 % is thermal, 15 % is radiation for a nuclear explosion. We don't know how the ratios are for things other than nukes, like explosion caused by magic or chakra.
We only use the 50% of the energy that is in the shockwave for calcs, as our calculation method is shockwave based. I.e. the formula tells you how strong of a nuke you would need to build to replicate the shockwave. But if you had an explosive device that converts 100% of its energy to shockwaves, you could create the same shockwaves as seen in the feat with 50% of a nukes power.
So since we don't know the ratio of the actual explosive attack for non-nukes, we take the low-end of assuming they are close to 100% shockwave. Hence we only credit 50% of the nuke value to them: They can have higher efficiency than nukes.

I will add in advance that the explosion displaying some thermal effects won't matter. Unless you can quantify the percentage (or calculate the thermal yield independently) we cant really assume it's 35%.

I see, so for the case of Shockwaves produced from like say a powerful stomp, would that be the same way, dividing by 50% to just be shockwave to remove the thermal and nuclear energy?
