Eleven deaths have been confirmed and more than 12,000 structures have been damaged or destroyed. More than 150,000 people remain under mandatory evacuation orders. Law enforcement sources told The Times that it’s likely many of the small fires will turn out to have been the work of arson.

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 County of Los Angeles Department of Medical Examiner on Friday released a list of 11 fatalities under investigation due to the recent wildfires, five of which occurred as a result of the Palisades Fire and six of which were tied to the Eaton Fire.

To the northeast, the Eaton Fire erupted in the Angeles National Forest, claiming at least five lives in the suburb of Altadena and damaging or destroying a likely 6,672 buildings as of early Thursday morning, according to the satellite analysis.

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,
