Los Angeles County has been devastated by two deadly wildfires that have become some of the most destructive in California history.

The Palisades and Eaton fires both erupted on Jan. 7, fueled by severe drought conditions and strong Santa Ana winds.

Dozens of people are believed to have died in the fires, which have burned down whole swaths of communities, including in the Pacific Palisades, Malibu, Altadena and Pasadena. More than 12,000 structures have been damaged or destroyed in the two fires, with the Eaton Fire the most destructive in Los Angeles history.

With the fires continuing to rage, the full scope of the lives lost and destruction remains to be seen.

While working to contain the Palisades and Eaton fires, firefighters also have had to contend with several smaller fires that have ignited amid the hazardous fire conditions.

Here’s a look at how the deadly blazes unfolded.

A dayslong red flag warning goes into effect for parts of Los Angeles and Ventura counties, with very strong winds in the forecast amid dry conditions.

The Bureau of Alcohol, Tobacco, Firearms and Explosives is leading a task force investigating the cause and origin of the fires, officials announce. The task force is made up of local, state and federal partners designed to investigate the cause of these fires and to see if there’s any connection between them.

Newsom also announces he is doubling the California National Guard’s deployment to the Los Angeles fires to 1,680 service members, as they are “continuing to rush in resources to rapidly respond to the firestorm in Los Angeles fueled by hurricane-force winds,” he says in a statement.

Four separate lawsuits are filed against Southern California Edison, a utility company in California, by homeowners and renters who lost their homes in the Eaton Fire. The lawsuits each allege the company failed to de-energize all of its electrical equipment despite red flag warnings issued by the National Weather Service.

A group of Pacific Palisades residents and businesses impacted by the Palisades Fire also files a lawsuit against Los Angeles’ Department of Water and Power, alleging that the city and its agency were unprepared for the Palisades Fire.

The cause of the fire has not yet been determined. Fire agencies are investigating whether Southern California Edison — a subsidiary of Edison International — infrastructure sites caused fires in areas devastated by the Eaton and Hurst wildfires.

Pedro Pizarro, the president and CEO of Edison International, tells “Good Morning America” that the company cannot yet rule out the possibility that its energy infrastructure played a role in the fires, as they have not yet been able to examine the equipment.
