2020 Oregon wildfires
Natural disasters in the USA
From Wikipedia, the free encyclopedia
The 2020 Oregon wildfire season was the most destructive on record in the state of Oregon. The season is a part of the 2020 Western United States wildfire season. The fires killed at least 11 people, burned more than 1,000,000 acres (400,000 ha) of land, and destroyed thousands of homes.[2]

Background
"Fire season" in Oregon typically begins in mid-May and ends with the first rains that normally begins in late September. Drought, snowpack levels, and local weather conditions play a role in Oregon's fire season, particularly in Eastern and Southwest Oregon. During peak fire season from July to September, most wildfires are caused by lightning, while ignitions in the early and later parts of the season are related to humans. Warm, dry conditions in summer heighten the wildfire risk. After over 100 years of fire suppression and prevention of all fires, there is now an abundance of fuel. Climate change is leading to a reduced snowpack with an earlier and reduced snowmelt, so there is a higher risk for areas that receive wildfires.[3]
Timeline
The Oregon Department of Forestry declared fire season beginning on July 5, 2020, signaling the end of unregulated debris burning outdoors.[4]
In early September, unusually high winds and continued dry weather caused the rapid expansion of multiple wildfires in Oregon. Over 1,000,000 acres were burned, and about 40,000 people were evacuated, with about 500,000 people in evacuation warning areas. The cities of Phoenix, Talent, Detroit, Idanha, and Gates in Oregon were substantially destroyed by the Almeda Drive and Santiam Fires respectively. State-wide, at least 7 people have been killed.[5][6][7]
In the Almeda Drive Fire area — between Ashland, Talent, and Phoenix — more than 2,800 structures were destroyed. Around the South Obenchain Fire, which stretched from Shady Cove nearly to Butte Falls, 153 structures were lost. Jackson County Sheriff Nathan Sickler said that these numbers do not differentiate between homes, businesses, outbuildings, and other structures. Assessing the precise nature of those structures lost would fall to local teams in the days and weeks ahead.[8][9]
Officials stated that the Almeda Drive Fire was human-caused.[9] On September 11, a man was arrested for arson, for allegedly starting a fire that destroyed multiple homes in Phoenix and merged with the Almeda Drive Fire.[10] A separate criminal investigation into the origin point of the Almeda Drive Fire in Ashland was ongoing as of September 2020.[10]
Causes
Through the end of July 2020, 90% of Oregon's wildfires had been caused by humans versus a yearly average of 70%, possibly because of increased outdoor recreation due to the COVID-19 pandemic.[11]
Rumors and theories
Rumors spread on social media that antifa activists were deliberately setting fires and preparing to loot property that was being evacuated. Some residents refused to evacuate based on the rumors, choosing to defend their homes from the alleged invasion. Authorities pleaded with residents to ignore the rumors.[12] One Facebook post shared thousands of times falsely stated, "KXL Radio in Portland reported today that Firefighters are now being shot at by suspected Antifa and BLM members."[13] QAnon followers participated in the misinformation, with one false claim that six antifa activists had been arrested for setting fires amplified by Q specifically.[14][15] There were also rumors that members of far-right groups had started some of the fires, though authorities labeled the claims as false, saying that people needed to question claims that they found on social media.[16]
Senator Jeff Merkley, (D-OR) decried President Donald Trump's comments blaming forest management for the fires as a "devastating lie.” Speaking on This Week with George Stephanopoulos, Merkley blamed climate change for the fires.[17]
One of the major fires, the Almeda fire in Southern Oregon, was worsened by a second blaze that was allegedly the result of arson. The first origin point of the fire was still under active investigation as of late 2020, and arson was suspected there, as well.[18][19]
Several small brush fires in Portland that were quickly put out were also the result of arson by a suspect who was apprehended, released, and then started several more.[20]

Notes
- Containment means that fire crews have established and secured control lines around the fire's perimeter. These lines are artificial barriers, like trenches or cleared vegetation, designed to stop the fire's spread, or natural barriers like rivers. Containment reflects progress in managing the fire but does not necessarily mean the fire is starved of fuel, under control, or put out.[21]
