CoreLogic’s annual Natural Hazard Risk Summary and Analysis released in late January shows that 2017 was a year of relatively average activity for most U.S. natural hazards with the exception of wildfires in California and flooding from Hurricanes Harvey and Irma.
The annual report reviews hazard activity in the U.S. including events for flooding, earthquake, wildfire, wind, hail, tornado and hurricanes, as well as several international events including Hurricane Maria in Puerto Rico, a magnitude 7.1 earthquake in Mexico and Cyclone Debbie in Australia.
Wildfires were also called out in the report.
The total number of acres burned (9,791,062, acres) in 2017 is the third highest in U.S. history, preceded by 2015 (10,125,149 acres) and 2006 (9,873,745 acres), the report shows.
