LA fires: Data and videos reveal scale of ‘most destructive’ blazes in modern US history
The fires that have been raging in Los Angeles County this week may be the “most destructive” in modern US history.
In just three days, the blazes have covered tens of thousands of acres of land and could potentially have an economic impact of up to $150bn (£123bn), according to private forecaster Accuweather.
Sky News has used a combination of open-source techniques, data analysis, satellite imagery and social media footage to analyse how and why the fires started, and work out the estimated economic and environmental cost.
More than 1,000 structures have been damaged so far, local officials have estimated. The real figure is likely to be much higher.
“In fact, it’s likely that perhaps 15,000 or even more structures have been destroyed,” said Jonathan Porter, chief meteorologist at Accuweather.
These include some of the country’s most expensive real estate, as well as critical infrastructure.

Accuweather has estimated the fires could have a total damage and economic loss of between $135bn and $150bn.
“It’s clear this is going to be the most destructive wildfire in California history, and likely the most destructive wildfire in modern US history,” said Mr Porter.
“That is our estimate based upon what has occurred thus far, plus some considerations for the near-term impacts of the fires,” he added.
The calculations were made using a wide variety of data inputs, from property damage and evacuation efforts, to the longer-term negative impacts from job and wage losses as well as a decline in tourism to the area.
The Palisades fire, which has burned at least 20,000 acres of land, has been the biggest so far.

Satellite imagery and social media videos indicate the fire was first visible in the area around Skull Rock, part of a 4.5 mile hiking trail, northeast of the upscale Pacific Palisades neighbourhood.
These videos were taken by hikers on the route at around 10.30am on Tuesday 7 January, when the fire began spreading.
At about the same time, this footage of a plane landing at Los Angeles International Airport was captured. A growing cloud of smoke is visible in the hills in the background – the same area where the hikers filmed their videos.
The area’s high winds and dry weather accelerated the speed that the fire has spread. By Tuesday night, Eaton fire sparked in a forested area north of downtown LA, and Hurst fire broke out in Sylmar, a suburban neighbourhood north of San Fernando, after a brush fire.
These images from NASA’s Black Marble tool that detects light sources on the ground show how much the Palisades and Eaton fires grew in less than 24 hours.
On Tuesday, the Palisades fire had covered 772 acres. At the time of publication of Friday, the fire had grown to cover nearly 20,500 acres, some 26.5 times its initial size.
The Palisades fire was the first to spark, but others erupted over the following days.
At around 1pm on Wednesday afternoon, the Lidia fire was first reported in Acton, next to the Angeles National Forest north of LA. Smaller than the others, firefighters managed to contain the blaze by 75% on Friday.
On Thursday, the Kenneth fire was reported at 2.40pm local time, according to Ventura County Fire Department, near a place called Victory Trailhead at the border of Ventura and Los Angeles counties.
This footage from a fire-monitoring camera in Simi Valley shows plumes of smoke billowing from the Kenneth fire.
Sky News analysed infrared satellite imagery to show how these fires grew all across LA.
The largest fires are still far from being contained, and have prompted thousands of residents to flee their homes as officials continued to keep large areas under evacuation orders. It’s unclear when they’ll be able to return.
“This is a tremendous loss that is going to result in many people and businesses needing a lot of help, as they begin the very slow process of putting their lives back together and rebuilding,” said Mr Porter.
“This is going to be an event that is going to likely take some people and businesses, perhaps a decade to recover from this fully.”

Kristi Noem: Top Trump official’s handbag – containing $3,000 in cash and security pass – stolen in burger restaurant
A bag belonging to the US Homeland Security Secretary was stolen on Sunday night – containing thousands of dollars in cash and an ID card that gives access to secure agency buildings.
Kristi Noem was eating at a Washington DC burger restaurant with family when a man in a face covering sat near her table and stole her purse, according to two people familiar with the theft.
Officials confirmed the theft to Sky News’ US partner NBC News on Monday.
The cabinet secretary was carrying $3,000 (£2,243) in cash because “her entire family was in town including her children and grandchildren”, Department of Homeland Security spokesperson Tricia McLaughlin told NBC.
“She was using the withdrawal to treat her family to dinner, activities and Easter gifts.”

Just before 8pm, a man wearing an N-95 mask walked into the restaurant and up a few stairs to where Ms Noem was eating dinner.
He sat near her table and moved his chair close to hers before sliding her purse toward him with his foot, according to surveillance footage viewed by law enforcement, the sources said.
Within minutes, the man had Ms Noem’s purse under his jacket and walked out of the restaurant.
At least two on-duty members of the US Secret Service were in the restaurant – between Ms Noem and the front doors – according to a source who witnessed the meal.
They said the restaurant wasn’t very busy at the time.
The purse also contained credit cards, blank cheques, her passport, driver’s licence and a set of keys.
It’s unclear whether Ms Noem was specifically targeted – and investigators are looking into whether the man knew who the purse belonged to.
When asked about the incident, Ms Noem said: “I don’t think I can comment on it yet. It’s not resolved yet.”
She said the Secret Service was aware but said she hadn’t spoken to agency personnel about what happened.

Starmer and Zelenskyy discuss ending Russia’s ‘brutal war’ – as Putin says says he is open to bilateral talks on longer ceasefire
Sir Keir Starmer and Volodymyr Zelenskyy spoke about ending Russia’s “brutal war” on Ukraine in their latest phone call on Easter Monday, as Vladimir Putin said he was open to bilateral talks.
The prime minister and Ukrainian president spoke on Monday afternoon, when Sir Keir “reiterated his iron-clad support for Ukraine“.
A Downing Street spokesperson added that the prime minister “said that the UK supports Ukraine’s calls for Russia to commit to a full ceasefire and that now is the time for Putin to show he is serious about ending his brutal war”.
“They discussed the latest developments on the Coalition of the Willing, and looked forward to further progress towards a just and lasting peace,” the spokesperson added.
Mr Zelenskyy later said on social media that he had a “good and detailed conversation” with the prime minister, and added Ukrainian officials will be in London for talks on ending the war with Russia on Wednesday.
“We are ready to move forward as constructively as possible, just as we have done before, to achieve an unconditional ceasefire, followed by the establishment of a real and lasting peace,” he added.
The Ukrainian president added that the 30-hour Easter truce, which both Kyiv and Moscow accuse the other of violating, showed that Russia “are prolonging the war”.
It comes as Mr Putin proposed bilateral talks with Ukraine on a longer ceasefire, which would mark the first time Russia held such talks since a failed peace deal soon after the invasion in 2022.
Speaking to a state TV reporter, the Russian president said: “We always have a positive attitude towards a truce, which is why we came up with such an initiative (the Easter truce), especially since we are talking about the bright Easter days.”
When asked about Mr Zelenskyy’s calls to extend the 30-hour ceasefire into a 30-day pause on civilian targets, he added: “This is all a subject for careful study, perhaps even bilaterally. We do not rule this out.”
The Ukrainian president said on Sunday evening that the Russian army had “violated Putin’s ceasefire more than 2,000 times” during the day, and accused Russia of “failing” to “uphold its own promise of a ceasefire”.

From Saturday: Why Putin offered an Easter truce?
It also comes after Donald Trump has said he hopes Russia and Ukraine “will make a deal this week,” after he and his secretary of state Marco Rubio warned that the US will walk away from efforts to broker a peace deal unless there are clear signs of progress soon.
The US president said on his Truth Social platform that both countries would “start to do big business” with the US after ending the war.

Last month, Ukraine accepted Mr Trump’s proposal for a 30-day truce, but Mr Putin refused to back a full 30-day ceasefire, saying crucial issues of verification had not been sorted out.
He then said he would agree not to target Ukraine’s energy infrastructure. However, both sides have accused each other of breaking the moratorium on attacks on energy targets and at sea.
The Royal Navy’s flagship HMS Prince of Wales is to begin an eight-month deployment to send a “powerful message” of the UK’s naval and air power.
Operation Highmast will take in joint exercises and visits with 40 countries across the Mediterranean, Middle East, southeast Asia, Japan and Australia.
The £3bn aircraft carrier is scheduled to sail from Portsmouth on Tuesday, accompanied from the navy base by Type 45 destroyer HMS Dauntless, to join a formation of warships, supply ships and aircraft off the coast of Cornwall.
HMS Prince of Wales, as the biggest class of ship in the Royal Navy, is leading Carrier Strike Group 25 (CSG25) with the involvement of around 2,500 personnel from the Royal Navy, 592 from the Royal Air Force and 900 from the Army.

Later during the deployment, as many as 4,500 military personnel will be involved in exercises in the Indo-Pacific region. Forces from Norway, Canada and Spain are among 12 other nations taking part in operations.
The CSG’s first task will be to join a NATO exercise off France testing aerial defences before the ships move on to the Mediterranean to work with an Italian-led carrier force and then head east via the Red Sea.

Other military assets include a contingent of up to 24 Royal Air Force F-35B Lightning fighter jets, Merlin Mk2 anti-submarine helicopters, Merlin Mk4 Commando and Wildcat helicopters along with T-150 Malloy and Puma drones.

Commodore James Blackmore, CSG commander, said the deployment would send a “powerful message” of the UK’s naval and air power.
He said: “It’s about supporting key trade routes that exist from the Indo-Pacific region to the UK, and supporting partners and allies in the region, showing that we are there as a capable and credible force should it be required.
“Operation Highmast will demonstrate credible deterrence and our support to NATO and the rules-based international order.”
Defence Secretary, John Healey MP, called it an “immensely complex operation” which sends “a powerful message of deterrence to any adversary”.
“This is a unique opportunity for the UK to operate in close coordination with our partners and allies in a deployment that not only shows our commitment to security and stability, but also provides an opportunity to bolster our own economy and boost British trade and exports,” he added.
