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,

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.

Three hundred Oregon firefighters have arrived in Southern California, and many of them have started fighting the fires that have devastated Los Angeles and killed at least 10 people.

A new fire — the Kenneth Fire — erupted Thursday afternoon, so far spreading across 960 acres in Los Angeles and Ventura counties. The California Department of Forestry and Fire Protection says that blaze is 35% contained.

Two Los Angeles County wildfires which tore through more than 34,000 acres in four days, killing at least 10 people and destroying more than 10,000 structures, are now among the 20 most destructive fires recorded in the state of California.

Firefighters made significant gains Thursday at slowing the spread of the major fires, but overall containment remained far out of reach.
