Park Fire Becomes Fourth Largest in California's History

Over 6,000 firefighters battle the blaze as it threatens homes and critical infrastructure in the state's Central Valley.

The Park Fire, allegedly started by arson, has burned over 400,000 acres since July 24.
Containment efforts have reached 27%, but hot, dry conditions and rugged terrain pose ongoing challenges.
More than 560 structures have been destroyed, and over 4,000 residents have been evacuated.
Firefighters face additional threats from potential thunderstorms and lightning strikes.
International firefighting aid is expected from Australia and New Zealand to bolster U.S. efforts.
