LOS ANGELES (AP) — When disaster strikes, government emergency alert systems offer a simple promise: Residents will get information about nearby dangers and instructions to help them stay safe.
As the and other major emergencies have shown, alerts rely on a complicated chain of communication between first responders, government administrators, third-party companies and the public.
Sometimes, the chain breaks.
After the wind-driven wildfires broke out in Southern California on Jan. 7, evacuation orders for some neighborhoods — including the part of Altadena where the majority of deaths occurred — came . On Tuesday, Los Angeles County officials approved an outside review of how alerts functioned in the Eaton Fire and Palisades Fire in response to residents’ demands. City officials declined to answer The Associated Press' questions about , though Fire Capt. Branden Silverman said responding to a fire and determining evacuation needs can take some time.
It’s an increasingly common issue. After-action reports and investigations revealed issues with alert systems in other California blazes: in , which killed 22 people in Santa Rosa; the in ; the , which started the same day and killed three in Malibu; as well as in Colorado's , which destroyed more than outside Denver; and in Hawaii's , which decimated that historic town and .
It could take months to know why some evacuation orders lagged in the Los Angeles fires.
Several residents who lost homes in the Eaton Fire told the AP they received no notifications about their neighborhoods. For others, the first warning was an urgent text message in the middle of the night.
Susan Lee Streets, who signed up for alerts through Nixle, did not get any alerts specific to her west Altadena neighborhood before she and her family left of their own accord around 10 p.m. after losing power and cell reception.
“If we had even been informed that houses and other structures were burning down, we would have known better what was happening,†she said. “We almost went to sleep that night with two kids and a dog and two cats in the house.â€
Only after 3 a.m. did she see a notification about evacuating her neighborhood on her phone. Destroyed along with the house are the Christmas ornaments she saved for her children, and countless other family keepsakes.
“We lost everything, everything,†Streets said, breaking into tears.
Tricia Wachtendorf, director of the Disaster Research Center at the University of Delaware, said alerts have to be specific and clear. Research has shown that for them to be effective, people have to hear, understand, believe, personalize and confirm them before they react.
“Just because you send the message at 3 a.m. doesn’t mean someone is hearing it,†Wachtendorf said.
The hours between midnight and 3:30 a.m. appear to have been particularly challenging for first responders in Los Angeles County, based on an AP review of scanner traffic recordings and data from CalFire, the state's chief fire agency; the Federal Emergency Management Agency; and the Watch Duty app.
Resources were stretched thin, and hurricane-force winds had grounded air support, limiting authorities' ability to get a top-down perspective on the flames.
Calls reporting burning homes were flooding in as embers blew onto roofs and yards. During one half-hour period, 17 new addresses were relayed to firefighters, even as some crews ran low on fuel.
By 12:07 a.m., CalFire records show, dozens of neighborhoods had been ordered to evacuate because of the Eaton Fire, all of them east of Altadena's North Lake Avenue. None of the neighborhoods to the west — where all of the 17 confirmed fatalities occurred, as first reported by the Los Angeles Times — had received evacuation warnings or orders, despite house fires being reported there more than an hour earlier.
Over the next three hours, fire crews would go from begging for resources on the eastern flank of the blaze to radioing the command center to make sure it knew the fire was spreading west along the foothills near Sunset Ridge.
Just before 3:30 a.m., evacuation orders expanded significantly, with residents in 12 areas of Altadena and elsewhere told to “leave now.â€
Jodi and Jeff Moreno first heard about the fire from a neighborhood app. But the first official warning only came around 2:30 a.m., when authorities yelled through a bullhorn to evacuate. The couple grabbed their three daughters, their dog and some important papers, and fled.
There were no text alerts until after they were gone.
“On the neighborhood apps, some people were going, some people were staying. It was a wide variety of responses. We were navigating it on our own,†Jodi Moreno said. “It’s hard for us to gauge where exactly is that fire, where are the embers blowing. ... Those are things I would rely on people who are monitoring it†for information.
Desperate for more information, both the Morenos and Streets downloaded the Watch Duty app, which maps evacuation zones and consolidates information from multiple sources into a single stream. Launched in 2021 and today covering 22 states, it became a lifeline for them.
“The ideal system for warning people is informing them, right?†said Nick Russell, vice president for operations at Watch Duty.
“There’s certainly diligence necessary in the execution of official evacuation warning and orders or shelter in place, whatever the condition might be,†he said. "But telling people why that discussion is taking place between law enforcement and fire is important. And that’s what we’re doing.â€
The process of issuing evacuation notices starts with firefighters or other personnel on the ground recommending action, Russell said. It then moves up the chain of command to sheriffs, who ultimately put out any order.
During major emergencies that communication can be hampered by issues such as limited radio connectivity, wind noise or other technical problems. Incident command stations may have trouble synthesizing the large amounts of information they are getting from different agencies, something that is critical for understanding the scope of an emergency like a fire.
In Los Angeles County, residents who sign up for emergency notifications through the AlertLACounty website are then directed to a list of 57 links to other specific neighborhood or city alert system signups, as well as a general one covering 19 other cities. The city of Los Angeles and the Sheriff's Department also have alert systems.
It is not clear how the overlapping systems, which use different software programs, work together, or whether officials coordinate.
A 2024 Hazard Mitigation plan directed the city's Emergency Management Department to assess gaps in alert and warning systems in areas with poor cellphone connectivity and then implement a solution to ensure alerts reach people. But that goal was given a “medium†priority level and a long-term timeline, with completion expected sometime in the next 10 years.
Meanwhile, the county's Hazard Mitigation Plan, last updated in 2020, did not include a focus on emergency alerts or public notifications. Instead its high-priority goals had to do with educating people about wind's impact on wildfire risk and with community wildfire protection.
Officials at the County’s Coordinated Joint Information Center declined to comment other than to say that an independent review of evacuations and emergency notifications is planned and the Office of Emergency Management, County Fire Department and Sheriff’s Department plan to fully engage with it.
