What defines running fire behavior?

Running fire behavior is characterized by a fire that spreads rapidly and has a clearly defined front or head. This type of behavior typically occurs under certain environmental conditions, such as low humidity, high temperatures, and strong winds, which provide ample fuel and increase the intensity of the fire. A running fire can quickly move through the landscape, consuming fuel with a high rate of spread, which makes it particularly dangerous and challenging to control.

The distinction of having a well-defined head is significant, as it indicates the fire’s intensity and the speed at which it is advancing. Understanding this behavior is crucial for fire management and safety, particularly for those involved in firefighting and land management, as it helps in predicting and mitigating fire risks in affected areas.
