Fri Jan 10 11:50:00 UTC 2025: ## Power Grid Faults Skyrocket Before Major LA County Fires

**Los Angeles, CA** – A surge in power grid faults in the hours leading up to three devastating wildfires in Los Angeles County is raising concerns about a potential connection, according to data from Whisker Labs, a company that monitors electrical activity. The Eaton, Palisades, and Hurst fires have collectively destroyed or damaged over 9,000 structures, displacing at least 130,000 residents and resulting in ten deaths.

Whisker Labs CEO Bob Marshall revealed that the areas affected experienced a dramatic increase in grid faults—caused by events such as tree branches or wires contacting each other—immediately before the fires ignited. For example, the Palisades fire area saw 25 faults in the hour before the blaze and 18 during the hour it began. The Eaton fire area registered 50 faults during the hour of ignition, and the Hurst fire area saw 51 faults in the hour it was reported, following four hours of exceptionally high fault levels (120 faults total).

While Marshall emphasizes that a direct causal link hasn’t been definitively established, he notes that a single spark from a fault is sufficient to ignite a fire. He highlights that power lines remained energized despite the high number of faults in the hours leading up to each fire. “The utilities don’t have the sensors to know this is occurring,” he stated, emphasizing the value of his company’s data in identifying grid stress.

Although investigations are ongoing, officials from the Los Angeles County Fire Department and the U.S. Forest Service have not yet determined the official cause of the fires. The investigation into the Eaton fire is considering various factors, including public activity in the area and the presence of power lines. The cause of the Palisades fire is also under review.

This incident echoes the Camp Fire of 2018, where Pacific Gas & Electric equipment was determined to be the cause. The current situation underscores the potential for power grid failures to trigger catastrophic wildfires, especially given the ongoing extreme weather conditions in California. Experts warn that these fires could ultimately become the costliest wildfire disaster in U.S. history.
