The Palisades and Eaton fires, two of the deadliest and most destructive wildfires in California history, reached 100 percent containment more than three weeks after they began.

After nearly a month, the Palisades and Eaton fires in Los Angeles County have reached 100% containment, according to the California Department of Forestry and Fire Protection. The two blazes started on Jan.

Containment measures the percentage of a fire's perimeter that firefighters have under control. Parts of the fire's interior may still be burning.
