Here's all you need to know about devastation from Los Angeles wildfires

Fires ripping through the Los Angeles area have killed at least 16 people, displaced thousands of others and destroyed more than 12,000 structures while burning through an area larger than the city of San Francisco.

The blazes started last Tuesday, fuelled by fierce Santa Ana winds that forecasters expect to kick back up through at least midweek. Cal Fire reported the Palisades, Eaton, Kenneth and Hurst fires had consumed about 160 square kilometres.

Five deaths were attributed to the Palisades Fire along the coast and 11 deaths resulted from the Eaton Fire further inland, the LA County medical examiner's office said. At least 16 people were missing, and authorities said that number was expected to rise. 

While a cause for the fires has yet to be determined, early estimates indicate they could be the nation's costliest ever. Preliminary estimates by AccuWeather put the damage and economic losses at between $ 135 billion and $ 150 billion.

Thousands remain evacuated or without power  The flames have threatened and burned through several highly populated neighbourhoods over the past week, including Pacific Palisades, Altadena and others.

About 150,000 people were under evacuation orders with more than 700 taking refuge in nine shelters, officials said.

Cal Fire reported containment of the Palisades Fire at 11 per cent and the Eaton Fire at 27 per cent on Sunday.

The Kenneth Fire, which broke out near West Hills in the San Fernando Valley, was 100 per cent contained as of Sunday morning, while the Hurst Fire was 89 per cent contained.

Nearly 70,000 customers were without power across California as of Sunday morning, more than half of them in Los Angeles County, according to PowerOutage.us, which tracks outages nationwide.

Sewer, water and power infrastructure across the region has been significantly damaged, officials said.

The National Weather Service warned that strong Santa Ana winds could soon return and issued red flag warnings for severe fire conditions through Wednesday. The winds have been largely blamed for turning the wildfires into infernos that levelled entire neighbourhoods around the city where there has been no significant rainfall in over eight months.

Thousands have fled and many have lost their homes, including Hollywood stars Billy Crystal and Mandy Moore and Los Angeles Lakers head coach JJ Redick.

Fires scorched more than just landmarks and celebrity homes  While the fires have reduced a number of celebrity mansions and movie landmarks to ashes, they also burned through a haven in Altadena for generations of Black families avoiding discriminatory housing practices elsewhere. They have been communities of racial and economic diversity, where many people own their own homes.

The fires have destroyed several places of worship, including a mosque, a synagogue, a Catholic parish and a half-dozen Protestant churches.

Investigators studying cause of fires  No cause has been determined yet for the fires.

Lightning is the most common source of fires in the US, according to the National Fire Protection Association, but investigators quickly ruled that out. There were no reports of lightning in the Palisades area or the terrain around the Eaton Fire, which started in east Los Angeles County.

The next two most common causes are fires intentionally set and those sparked by utility lines.

Several events have been cancelled and postponed  The Critics Choice Awards rescheduled Sunday ceremonies in Santa Monica for January 26.

The organisation that puts on the Oscars extended the voting window for Academy Award nominations and delayed next week's planned nominations announcement.

The NFL moved the Los Angeles Rams' wild-card playoff game against the Minnesota Vikings to Arizona because of the fires. The game will be played Monday night. And the NBA postponed the Lakers' game against the Hornets.

NBA games are scheduled to return to Los Angeles on Monday night, with the Clippers hosting the Miami Heat and the Lakers set to host the San Antonio Spurs. It'll be the Clippers' first game in five days after having their home game against Charlotte on Saturday postponed. The Lakers had two home games pushed back.

The California Department of Education released a statement Wednesday saying 335 schools from Los Angeles, San Bernardino, Riverside, Ventura, and San Diego counties were closed. It was unclear how many would be closed Monday.

Accusations of leadership failures are percolating LA Mayor Karen Bass faces a critical test of her leadership during the city's greatest crisis in decades, but allegations of leadership failures, political blame and investigations have begun.

California Governor Gavin Newsom on Friday ordered state officials to determine why a 440 million-litre reservoir was out of service and some hydrants had run dry.

Los Angeles Fire Chief Kristin Crowley said city leadership failed her department by not providing enough money for firefighting. She also criticised the lack of water.
