The massive Rim Fire burning in and around California’s Yosemite National Park is now the largest U.S. wildfire in 2013 and currently the nation’s top priority as many residents remain evacuated as of Saturday morning (31-August).
As of Sat evening, Inciweb is reporting the Rim Fire is 222,777 acres and 40% contained with over 5,000 personnel battling the blazes, and officials are projecting they may have full containment by late September.
Unfortunately this beast is human-caused and, although investigators have not determined the official cause yet, a local Fire Chief has indicated it may be the result of illegal pot growers.
According to National Parks Service Fire and Aviation Mgmt, as many as 90% of wildland fires in the U.S. are caused by humans. Some human-caused fires result from…
- campfires left unattended
- burning of debris
- negligently discarded cigarettes
- off-road vehicles
- firearms + exploding targets
- intentional acts of arson
The remaining 10% are started by lightning or lava. In addition, wildfires caused by lightning burn an average of 5.5 million acres annually.
Acreage burned comes from a variety of factors…
- climate shift to a hotter, drier West after decades of cooler weather
- pine beetle infestations that create more fuel to burn
- decades of fire suppression
Even though it seems like much of the western U.S. is burning, the National Interagency Fire Center reports 34,388 fires have burned almost 3.8 million acres in the U.S. from January 1 – August 31, 2013 … which is well below the 10 year average of 54,072 fires that burned 6 million acres for this same time period.
