New Timeline of Deadliest California Wildfire Could Guide Lifesaving Research and Action

NIST researcher and fire protection engineer Alexander Maranghides views a landscape marred by the Camp Fire during a field data collection deployment.

On a brisk November morning in 2018, a fire sparked in a remote stretch of canyon in Butte County, California, a region nestled against the western slopes of the Sierra Nevada mountains. Fueled by a sea of tinder created by drought, and propelled by powerful gusts, the flames grew and traveled rapidly. In less than 24 hours, the fire had swept through the town of Paradise and other communities, leaving a charred ruin in its wake.


The Camp Fire was the costliest disaster worldwide in 2018 and, having caused 85 deaths and destroyed more than 18,000 buildings, it became both the deadliest and most destructive wildfire in California’s history, two records the fire still holds today.


What made the Camp Fire so devastating? And what lessons can we learn to prevent another disaster of this scale? Researchers at the National Institute of Standards and Technology (NIST) have begun to answer these questions by investigating the conditions leading up to the fire and meticulously reconstructing the sequence of events describing the first 24 hours of its progression. A new report containing the timeline identifies areas where more research is needed to improve life safety and reduce structural losses. It also offers a detailed look at how a large and deadly fire advances — information that will become increasingly valuable as fire seasons continue to intensify.
