indentations in the fire edge formed by fingers or slow |\ |\ |\ |\ |\ |\ |\ |\ |\ |\



burning areas |\




Island - CORRECT ANSWERS ✔✔Area of unburned fuel
|\ |\ |\ |\ |\ |\ |\ |\



inside the fire perimeter
|\ |\ |\




Spot fire - CORRECT ANSWERS ✔✔Fire ignited outside the

perimeter of the main fire by a fireband |\ |\ |\ |\ |\ |\ |\




Smoldering - CORRECT ANSWERS ✔✔Fire burning without |\ |\ |\ |\ |\ |\ |\



flame and barely spreading
|\ |\ |\




Creeping fire - CORRECT ANSWERS ✔✔Fire burning with a
|\ |\ |\ |\ |\ |\ |\ |\ |\



low flame and spreading slowly
|\ |\ |\ |\

|\ |\ |\ |\ |\ |\ |\ |\



producing sparks or embers that are carried by the wind |\ |\ |\ |\ |\ |\ |\ |\ |\ |\



and which start new fires beyond the zone of direct
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\



ignition by the main fire |\ |\ |\ |\

|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\



independent of surface fire. Sometimes classes as |\ |\ |\ |\ |\ |\ |\



running or dependent to distinguish the degree of
|\ |\ |\ |\ |\ |\ |\ |\



independence from the surface fire. |\ |\ |\ |\




Flare up - CORRECT ANSWERS ✔✔Any sudden
|\ |\ |\ |\ |\ |\ |\



acceleration in the rate of spread or intensification. |\ |\ |\ |\ |\ |\ |\ |\



Relatively short-duration. Junipers cause a lot of these.
|\ |\ |\ |\ |\ |\ |\

|\ |\ |\ |\ |\ |\



of ascending hot air and gases rising from a fire and
