Arson is a prevalent cause of wildfires in California, with 10% to 15% of fires started intentionally each year. Due to climate change, longer fire seasons, and increased drought conditions, the risk of arson-related fires is on the rise. The number of acres burned due to arson in 2024 is the highest since 2014. Arson-ignited fires pose a greater risk when timber is dry, potentially leading to larger and more damaging blazes.
The arrest of arsonists can have a significant impact in reducing the number of fires, as individuals who set fires often do so serially over a short period of time. In California, 91 people were arrested on suspicion of arson by August 2024. Wildfire arsonists tend to be men who set multiple fires and may not be caught until they have done so repeatedly. The difficulty in investigating and prosecuting wildfire arson cases lies in the lack of physical evidence and challenges in determining the cause of the fires.
Despite successful prosecutions occasionally resulting in lengthy prison sentences, victims of arson-ignited wildfires often struggle to recover losses through insurance or restitution. The recent arrest of a suspect in the Park Fire, who faces 25 years to life in prison if convicted, highlights the long-lasting impact of arson-related fires on individuals and communities. Increased use of security cameras, smartphones, and satellite-tracking devices has helped Cal Fire investigators clear more cases, but the inherent risks of wildfires in California make prevention and prosecution challenging.
