Photos offer a glimpse at the scale of destruction that occurred in just a day and a half.
The situation is still ongoing and dangerous, with evacuation orders in many areas.
The Palisades and Eaton fires are ripping through parts of Los Angeles and causing mass destruction.
Firefighters are still struggling to contain the blazes, which grew rapidly and have continued for more than 24 hours.
The fires have destroyed at least 1,000 homes. Five people are reported dead. These counts are preliminary, as the situation is still dynamic.
It's difficult to grasp the scale of these fires, but emerging photos paint a grim picture.

More than 70,000 people were under evacuation orders on Wednesday afternoon. Officials have warned that people in many other surrounding regions should prepare to leave their homes at a moment's notice.
Pat Durland, a wildfire-mitigation specialist and instructor for the National Fire Protection Association with 30 years of federal wildfire management experience, told Business Insider that if he lived in the area, he would leave before evacuation orders even hit his home.
"I would have left and gone to the beach or gotten a hotel," he said.

Many people abandoned their cars and fled on foot.
Since then, the Palisades Fire has burned through more than 15,800 acres. This was the area with evacuation zones early Wednesday afternoon.The area of the Palisades Fire with evacuation zones as of 2:30 p.m. Pacific Time on Wednesday, from the California state fire agency, CalFire.

Hurricane-force winds peaked overnight and Wednesday morning, and firefighters were unable to contain the blazes.
"Despite the efforts we put in with well-trained firefighters and equipment and aircraft, the wind and the weather still are ruling these situations," Durland said of major, fast-moving fires like these.

The last two winters in Southern California have been quite wet, even causing flooding. That led to an explosion of grasses and shrubs, nearly twice as much as a normal season, according to the UCLA climate scientist Daniel Swain.
However, this winter has been different. Months without precipitation have dried out all that vegetation, blanketing the LA hillsides with fire fuel.
Grasses and shrubs help spread the fire, but it's "human fuels" that ignite homes, Durland said.A firefighter douses a hot spot near a home in the Pacific Palisades.

"It's bark mulch, it's ornamental grasses, it's structures that are readily flammable," Durland said.
"This is an urban fire. We're burning urban fuels," he added.
That means that cities and homeowners can do something about it. More fire-resistant landscaping and construction can help protect homes from future firestorms like this.
There are always houses that survive wildfires, Durland said, and everyone can learn from that.The Palisades Fire approaches homes on Tuesday.

It helps to build homes with ample space between them and maintain a perimeter of at least five feet that's totally free of dry or flammable vegetation or mulch.
Homeowners can also keep their roofs and gutters clear and remove anything flammable from underneath porches and decks.
The Palisades were full of multi-million-dollar homes, which means this could be the costliest fire in US history, Swain said.The remains of a home's staircase in the Pacific Palisades neighborhood of Los Angeles.
