However as The Instances first reported in January, evacuation orders weren’t issued for west Altadena till after 3 a.m., properly after the fireplace had threatened the world. Evacuation warnings for the world by no means went out.
All however one of many Eaton hearth’s 19 deaths occurred in west Altadena.
The Hearth Security Analysis Institute report, launched Thursday morning, doesn’t analyze why alerts had been delayed, however gives essentially the most detailed timeline but of the night time of the fireplace, together with new timestamps that present there have been indicators the fireplace was shifting towards west Altadena nearly six hours earlier than the world obtained any evacuation alert.
The report notes that there was “hearth unfold to the west” as early as 9:30 p.m. on Jan. 7, pointing to a number of spot fires west of the fireplace origin.

A number of hearth officers beforehand advised The Instances that they weren’t conscious of wind shifting to the west till round 2 a.m, however the report reveals that the indicators had been there earlier, each in wind measurements and in 911 calls.
Pasadena Hearth Chief Chad Augustin advised The Instances in Could that round 2 or 3 a.m. command workers on the Rose Bowl began receiving “good intel” from groups on the bottom that the winds had been shifting and pushing the fireplace west, requiring extra evacuations, however he didn’t recall the precise timing.

Though the doc doesn’t present a lot evaluation, specializing in the details of the circumstances, preparations and response, the findings had been clear that “the ember forged contributed to the fast enlargement,” Derek Alkonis, one of many authors, stated at a information convention on Wednesday, forward of the report’s launch.
The delayed evacuations have prompted scrutiny from public officers and Altadena residents in regards to the L.A. County Hearth Division’s dealing with of the wind-driven inferno.
Michael Gollner, an affiliate professor of mechanical engineering at UC Berkeley who leads its Hearth Analysis Lab, stated the timeline offered within the report is a crucial place to begin to grasp what occurred in the course of the hearth response.
However he famous there was nonetheless little details about some essential particulars: What was the chain of command on the primary day of the Eaton hearth? How was data being shared? What different points had been incident commanders coping with on the identical time that might have affected evacuation selections?
“That’s what’s actually vital, how that data was handed on and the way a lot they knew that [the fire] was spreading into this space,” Gollner stated. “There’s much more to return and much more we’d like.”
Different already launched experiences in regards to the fires carried out by Los Angeles County and the town had been met with criticism from residents for being restricted in scope.
Final month, a report commissioned by Los Angeles County discovered {that a} common lack of planning, poor communication, understaffing and chaotic circumstances contributed to premature evacuation orders because the Eaton hearth tore by Altadena. However the report was extensively criticized for not answering key questions round evacuation failures, together with why county officers didn’t ship evacuation alerts to west Altadena till 3:25 a.m. or later.
Particulars within the state report shed some extra mild on what finally induced county hearth officers to develop evacuations to incorporate west Altadena.
At 10:50 p.m., a resident known as in to say that fireside was seen from her dwelling on East Calaveras Road in west Altadena. Virtually precisely an hour later, a Los Angeles County battalion chief reported a construction hearth at Glenrose Avenue and West Loma Alta Drive, even farther into west Altadena, in line with the report.

Across the identical time, county hearth officers had been defending constructions on East Mount Curve Avenue close to Lake Avenue. They had been compelled to go away after half-hour due to hazard from the erratic winds.
Regardless of all these indicators of accelerating hearth exercise in west Altadena, it might nonetheless take greater than an hour earlier than the evacuation order went out.
Gov. Gavin Newsom commissioned the Hearth Security Analysis Institute, based mostly in Columbia, MD, to conduct an investigation a few month after the Palisades and Eaton fires killed 31 individuals and destroyed 16,000 constructions throughout Los Angeles County. Researchers and engineers from the institute — which additionally carried out the post-incident evaluation for the state of Hawaii after the 2023 Maui hearth — deployed to Southern California to assemble proof to “construct a complete timeline of occasions and circumstances that may inform the evaluation of efficacy of the response.”
Thursday’s report gives a timeline of how the fires progressed and appears at state and native officers’ actions, climate circumstances, the emergency response and hearth suppression. It additionally features a assessment of 10 different fires that occurred in Southern California the identical month because the Eaton and Palisades fires.
The report additional captures the chaos and erratic nature of the wind-driven Eaton hearth and the challenges crews on the bottom confronted battling the inferno. Not solely was the fireplace shifting west sooner than beforehand reported, nevertheless it was additionally spreading east concurrently, in line with the report.
Simply earlier than 1 a.m., crews at completely different ends of the fireplace requested extra assets, asking for assist each to the east and west of the fireplace’s origin. Related accounts of the severity of the fireplace got here in from regulation enforcement from 1:11 a.m. to three:13 a.m., reporting homes on hearth in north Sierra Madre, in addition to in east and west Altadena.
The ember forged reworked what began as a wildfire right into a full-blown city conflagration. This possible made evacuations tougher, consultants have stated.
When hearth officers are contemplating evacuations, they often have a look at wind pace and course, topography and gas kind to assist information them, stated Matt Rahn, the founding director for the wildland city interface program at Cal State San Marcos and the analysis director for the Wildfire Conservancy.
However in a quickly shifting inferno the place embers are casting miles from the pinnacle of the blaze and igniting spot fires, it “makes it very troublesome to evacuate communities and predict the place an evacuation ought to happen,” Rahn stated.
“When all the sudden you’ve spot fires begin actually miles away from the fireplace entrance itself, it creates this complete new problem,” Rahn stated. “You’re not simply apprehensive about what’s occurring right here, you’re apprehensive about different incidents that will develop into bigger fires or, within the case of the Eaton hearth, an city conflagration. They’re very arduous to foretell they usually’re changing into extra frequent within the sorts of fires we expertise.”
The second section of the report, anticipated to be launched in mid-2026, will draw on data contained within the first report to supply evaluation and particulars on the effectiveness of officers’ efforts to stop the fires and alert residents. The experiences won’t delve into the reason for the fires.
Artwork Botterell, former senior emergency providers coordinator for the California Governor’s Workplace of Emergency Companies, stated the timeline was a mandatory first step. However though the timeline strategy may be helpful, Botterell stated, it additionally has limitations.
Botterell stated tendencies and variations in demographics, city planning, workforce growth, and infrastructure growth and upkeep may be more durable to identify in a collection of snapshots from a comparatively quick interval.
“New information is all the time useful, however often the blind spots lie within the questions we don’t ask,” Botterell stated. “A lot will rely upon the depth, perspective and independence of the evaluation that follows.”
