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.

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.

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.
