Theory 48/Fire regime/Termination phase
Termination Is Fuel Exhaustion
The claim
A fire stops when the ratio of available fuel to the heat needed to sustain combustion falls below one, not when it meets a barrier.
01Mechanism
The front advances only while fuel supplies net heat; the ratio determines the stop.
02Prediction
Burn perimeter should track fuel loading.
03Refutation
Perimeter tracking suppression effort would remove fuel.
