What Started the Pacific Palisades Fire?

Officials indicated that extremely high winds have worsened the fire if not directly caused it. Wind gusts increased overnight on January 7, and multiple outlets reported that gusts could reach up to 100 miles per hour in certain parts of L.A. County.

What Causes California Wildfires?

California wildfires are caused by a combination of natural and human factors. Drought, high temperatures, and strong winds, particularly from the Santa Ana winds, create ideal conditions for fire. Lightning strikes can ignite dry vegetation, while human activities like arson, faulty power lines, and outdoor equipment can trigger flames. Additionally, overgrown vegetation, climate change, and urban sprawl increase fire risk by providing more fuel and bringing wildfires closer to populated areas.

How Much of the L.A. Fires Have Been Contained?

As of now, the majority of the fires remain largely uncontrolled:

  • Palisades Fire: Over 15,832 acres burned, with 0% containment.
  • Eaton Fire: Over 10,600 acres burned, with 0% containment.
