Glossary: what each term means
Minimal

Barely moving. Low, thin smoke.

Smoldering

Burning without flame, in the ground or in roots. Can flare up days later.

Creeping

Moves slowly, hugging the ground.

Moderate

Spreads with low, steady flames.

Active

Spreading evenly and steadily, with visible flame.

Extreme

Fast and unpredictable.

Running

Runs along the ground much faster than a person walks.

Flanking

Grows along the sides, not head-on.

Backing

Moves against the wind or downhill, which makes it slower.

Crowning

Climbs into the treetops and jumps crown to crown. It can't be attacked from the ground.

Short Crown Runs

Climbs into the crowns in bursts and drops back down.

Torching

Whole trees flaring up like torches.

Isolated Torching

Single scattered trees flaring up whole, like torches.

Group Torching

Whole clumps of trees flaring at once.

Spotting

Wind carries embers through the air and starts new fires ahead of the front: that is how a fire jumps a road or a firebreak.

Wind Driven Runs

The wind pushes it in long runs in one direction.

The ones marked are the behaviors that make a fire harder to stop. They are not a warning or an instruction: they are the description written by the agency in charge. For decisions, always follow your emergency services.
