A year after the devastating fires ripped through L.A. County, AccuWeather estimates that total cost of the fires - between damage and economic loss - is as high as $275 billion. This update would make it the most expensive natural disaster in U.S. history even after accounting for inflation, according to the National Oceanic and Atmospheric Administration (NOAA).
Governments and industries across the board have spent the last year digging into why and how these fires got so out of control, using their research to enact policy and practice change that is intended to at least mitigate the chances of a similar event.
