Clearing the toxic remnants of burned buildings around Los Angeles will require a complex and expensive mobilization. California has been there before.

Los Angeles is reeling from the most destructive wildfires in its history, and firefighters are struggling to contain the devastating blaze.

Hollywood stars are sharing the devastation caused by the California fires and sharing "prayers and strength" for those affected.

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.

California homeowners shared video clips of the damaging flames plowing through the Pacific Palisades area as a fire continues to blaze since its start on Tuesday.
