When WUI becomes the city: Lessons from the 2025 Los Angeles fires for Australia's urban-wildland future

19 Aug 2026
IFE Australia | Meeting Room 211
The January 2025 Southern California fires did not behave like wildfires. They behaved like urban conflagrations — ignited at the wildland edge and consuming densely developed neighborhoods at a pace and scale that overwhelmed every layer of preparedness and response. The Palisades and Eaton fires together destroyed more than 16,000 structures, killed 32 people, and exposed a dangerous gap between how fire agencies plan for WUI events and how those events actually unfold when wind-driven fire enters the built environment.

Drawing on UL Research Institutes' Fire Safety Research Institute independent analysis — commissioned by the Office of the Governor of California — this session presents findings from the Phase 1 Southern California Fires Timeline Report and, where available, the Phase 2 Incident Analysis. Together, these reports examine fire progression, structure-to-structure spread, the role of built environment conditions, and the limits of agency response under simultaneous multi-incident conditions.

Australia knows this terrain. From Black Summer to growing WUI expansion across peri-urban corridors, the conditions that produced Los Angeles are not anomalies — they are a preview. This session translates what FSRI's science reveals into actionable implications for fire engineers, emergency managers, and policymakers preparing communities for the conflagrations ahead.
