Tens of thousands of people have fled their homes as a wildfire in the Pacific Palisades killed at least five people and burned more than 21,000 acres within three days, reaching 8% containment Friday as firefighting efforts continue.

Though the Palisades and Eaton fires are smaller, they rank high in structures burned. Combined, they would equal the second-most destructive California wildfire in history, with more than 9,000 structures burned, according to early Cal Fire estimates. A more detailed analysis of the total number of destroyed structures is still underway.

The deadly wildfires roaring through Los Angeles County entered a fourth day on Friday. At least 10 people have been killed, about 150,000 are under mandatory evacuation orders and more than 10,000 homes and other structures have been destroyed,
