OREANDA-NEWS. October 12, 2015. Impact Forecasting, Aon Benfield's catastrophe model development team, today launches the latest edition of its monthly Global Catastrophe Recap report, which evaluates the impact of the natural disaster events that occurred worldwide during September 2015. Aon Benfield is the global reinsurance intermediary and capital advisor of Aon plc (NYSE:AON).

The report reveals that several wildfires impacted California during the month; the Valley Fire, which occurred northwest of San Francisco, was the third-most damaging wildfire in state history, killing four people and destroying 1,958 homes and other structures. Forecast economic losses from the fire were in excess of USD1.5 billion, with preliminarily insured losses estimated at more than USD925 million.

Meanwhile, the Butte Fire, which occurred southeast of Sacramento and was the seventh-most damaging wildfire in state history, killed two people and caused total estimated economic losses of at USD450 million, with insurance losses expected to be above USD225 million.

With peak U.S. wildfire season in California having started in late September and lasting through early November, wildfires in 2015 have already caused more damage and financial loss in the U.S. than in any other year since 2007.

Adam Podlaha, Head of Impact Forecasting, said: "The severity of the September wildfires in California serves as a reminder of how costly the peril can be for the insurance industry. With insurers facing more than USD1.0 billion in claims payouts for the Valley and Butte fires alone, it makes it the costliest year for the peril since 2007. The peak of the California wildfire season is just beginning, and Impact Forecasting remains well suited to help our clients assess their risks given our brushfire model for the region."
