Knowledge of the fire containment process
It should be noted that full containment does not imply that the fire is extinguished. Here, it indicates that the wildfire has been surrounded by a control line, and it can no longer spread. A fully contained wildfire will not be likely to spread, but will continue burning in the perimeter of the containment. But when it comes to containing and controlling a wildfire, there is a big difference between the two.
Controlling the fire is the second action after fire containment has been done. A fire control involves protecting the fire so that it can not escape or transcend the containment line. Containment is also a component of a bigger program on dealing with a wildfire. This was usually put as a percentage, and it means the percentage of the fire perimeter enclosed/circled by a control line that firefighters establish.
Fire lighting is widespread in California
As per NIFC statistics of 2024, there were 305 fires in California due to lightning, and they burned 90,206 acres of wildland. Firefighters on the ground provide reports on the progress of the incident to the center command regularly. With the continuing construction of the fireline, the building inspectors or reinforcers are recording those specifics, and the mappers will input those to modify the containment percentage.
The TCU September Lightning Complex was an active fire that was successfully contained, proving the competence of multi-jurisdiction coordinated firefighting efforts. Although the fire has inflicted immense structure damage and consumed a lot of resources, the joint action helped stop the fire and save other communities, who otherwise might have been ruined in the region of four counties.
