What phenomenon occurs when a "sleeping" fire revives with explosive speed and energy?

Blow up
Flare up
Ignite
Reignite

The correct answer is: Blow up

The term that describes the phenomenon where a "sleeping" fire revives with explosive speed and energy is known as a "blow up." This occurs when conditions such as changes in wind, temperature, or availability of fuel allow a fire that seems to be extinguished or under control to suddenly re-ignite and spread rapidly. This phenomenon is particularly concerning in wildland firefighting, as it can catch firefighters off guard and pose significant safety risks. Understanding this term is crucial for recognizing the potential for fire behavior changes and ensuring safety protocols are in place during firefighting operations. Other terms like "flare up" or "reinignition" refer to similar but less intense occurrences where a fire may increase in intensity or start again, but they do not capture the rapid and explosive nature that a "blow up" entails. "Ignite" typically refers to the initial lighting of a fire rather than a revived fire behavior, which also differentiates it from the concept of a "blow up."
