How Do You Rate a Forest Fire?

Most of the news stories about the 43 large wildfires in the Western United States report some level of "containment" reached by firefighters. What does it mean to contain a fire, how is the percentage calculated, and when is a fire "controlled"?
To prevent a blaze from spreading, firefighters dig a "fire line" around its circumference. If three miles of fire line have been built around a fire that is 10 miles in circumference, then 30 percent of the fire is contained.(外周10マイルの火事に対して3マイルのトレンチなどのFirelineが作られると30％conainedされたという)
Fire lines are trenches dug to create a "fuel break" around the fire. Fires need fuel, oxygen, and heat to burn, and the easiest of the three to eliminate is fuel. Fire lines can also include "natural" barriers such as roads, rock bluffs, or streams.
Once a fire is fully contained, firefighters work on "controlling" it by battling it inside the containment line. A controlled fire is one that has no risk of expanding beyond the fire line.
