The Worst Wild Fires in World History
The Worst Wild Fires in World History
The Wallow Fire in Arizona and New Mexico has now become the largest in history for the southwestern United States with over 788 square miles (504,409 acres) charred so far, far surpassing the Rodeo-Chediski fire of 2002. It is now probably in the top ten largest single wild fires in U.S history (as of June 18th). I thought this an opportune time to look back and compare the magnitude of the fire with those in the past in both the United States and around the world.
Worst Wild Fires in U.S. History
The single worst wild fire in U.S. history, in both size and fatalities, is known as the Great Peshtigo Fire which burned 3.8 million acres (5,938 square miles) and killed at least 1,500 in northern Wisconsin and the Upper Peninsula of Michigan during the week of October 8-14, 1871. Many sources put the size of the fire at 1.2-1.5 million acres but that included only the area that was completely burned and not the additional 2.3 million acres in surrounding counties that also suffered burn damage (see maps below). Unattended fires at logging camps in the area most likely caused the fire. After a long hot and very dry summer strong warm autumn winds from the southwest fanned the fires out of control. Fire tornadoes were reported at several locations and the fire became so hot that people taking refuge in rivers were boiled to death.

Numerous other fires also broke out in Michigan at the same time, the worst of which burned an additional 1 million acres (1,562 square miles) in Michigan’s thumb region and in the southwestern portion of the state and killed 200 people mostly in and around Port Huron.
This map shows the locations of all the major fires that broke out in the Upper Midwest during the period of October 8-21, 1871.
Amazingly, the Great Chicago Fire of even greater fame also happened this same week (October 8-10) and remains the worst urban fire in U.S. history with over 300 killed (assuming we treat the deaths in San Francisco in 1906 as earthquake-related). In fact, there is a connection between the wild fires in Wisconsin and Michigan and that in Chicago. An apocryphal story (made up by a newspaper man) blamed the cause of the Chicago fire on a cow knocking a lantern over in a barn. In fact, it is likely the fire was caused by embers from fires burning in the woods west of town being blown by the same strong southwesterly winds (that fanned the flames in Wisconsin) into the city and ignited some of the wooden buildings which were predominate in the city at that time.

All in all, well over 2,000 people died and close to 5 million acres (7,800 square miles) burned during the weeks of October 8-21, 1871 in Wisconsin, Michigan, and Illinois. An intriguing, but most likely apocryphal, theory is that the fires were actually caused by the impact of fragments from Comet Biela that was observed at this time.
It should be noted that all of the deadliest wild fires in American history have occurred in the Upper Midwest. Other notable fires were the Cloquet, Minnesota fire of October 13-15, 1918 that killed as many as 1,000, and the Hinkley, Minnesota fire of September 1, 1894 that killed 400-800.
The worst wild fire in western history and the 2nd largest overall in the United States was the Great Fire of 1910. This massive forest fire burned some 3 million acres (4,700 square miles) in Idaho and Montana beginning on August 20-21, 1910. It killed at least 87 people, mostly ill-equipped firefighters, including a single crew of 28 who were overcome by the flames near Setzer Creek outside Avery, Idaho. The worst hit town was Wallace, Idaho, of which one-third was razed.

The fire was the culmination (as always) of a long dry summer that spawned a number of small fires that were whipped into a single huge conflagration by near hurricane-force winds on August 20th during the passage of a strong cold front. Smoke from the fire was observed as far east as upstate New York.
The 1910 fire was the seminal event that led to a policy of the U.S. Forest Service to prevent and battle all wild fires. This policy remains in force today but is of considerable controversy. The debate reached a head during the summer of 1988 when 800,000 acres (1,250 square miles) of Yellowstone National Park were burned.
California experiences large and destructive wild fires virtually every year, usually in October when the long dry season is coming to an end (normally there is no rainfall in California between May 15-October 15). The worst fires usually occur in the densely populated coastal regions between San Diego and San Francisco which are subject to powerful easterly winds, variously known as Santa Ana (in southern California) and Diablo (in central California). This wind phenomenon is most common during the months of September and October.
The largest single fire in modern California history was the so-called Cedar Fire in San Diego County during October 2003. It burned 280,278 acres (438 square miles), destroyed 2,820 buildings, and killed 15 people.

The deadliest urban wild fire, however, was that which burned into the cities of Oakland and Berkeley on October 20, 1991. Although only about 1,500 acres burned, the fire consumed 3,500 homes and apartment buildings and killed 25. This fire was caused by a Diablo wind event and remains the deadliest and costliest urban wild fire in U.S. history.

The largest fire on record in the Pacific Northwest was the Syskiyou National Forest Fire of July 12-15, 2002 in Southern Oregon. Some 500,000 acres (781 square miles) burned. Fortunately, there were no casualties or major structural losses since the fire was contained largely to a wilderness area.
NORTHEAST AND CANADA
The largest (and deadliest) wild fire in Canadian history as well as in the northeast of the U.S. was the Miramichi Fire of October 7, 1825. An estimated 3 million acres (4,685 square miles) of forest burned in the Canadian province of New Brunswick and in the U.S. state of Maine. At least 160 people died but the toll may have been much higher since an unknown number of loggers in the area may have perished.
A wild fire in Acadia National Park, Maine during October 25-27, 1947 destroyed much of Bar Harbor, burned 205,678 acres (321 square miles), and killed 16.
Canada’s largest fire in modern history was the Chapleau-Mississagi fire of May and June, 1948 in northeastern Ontario. It burned 691,880 acres (1,081 square miles) and smoke from the fire was dense enough in Texas to cause streetlights to turn on during the daytime in some cities. A smaller but deadlier wild fire, the so-called Porcupine Fire, burned 494,000 acres (772 square miles) in northern Ontario in July 1911. At least 70 people died in several mining camps and communities in the area.

A series of large fires in Alaska during the summer of 2004 burned a combined 5 million acres (7,800 square miles), the most on record for the state although there is plenty of evidence that enormous fires have frequently raged over thousands of square miles in events prior to the modern settlement of the state.
Wild Fires Around the World
Perhaps the largest wild fire in modern world history was that known as The Black Friday Bushfire in Australia’s Victoria State on January 13, 1939. Some 5 million acres burned (7,800 square miles) and 71 died. About 75% of the entire state was affected and 1,100 homes and log mills were destroyed. Ash from the fires fell in New Zealand some 2000 miles to the east.
Australia’s deadliest wild fire, and the nation’s worst natural disaster, was the Black Saturday Fire of February 7-March 14, 2009. A swarm of fires burned 1.1 million acres (1720 square miles) and killed 173, many victims died in their automobiles trying to outrun the flames. 3,500 structures burned across the state of Victoria. The exact cause of the fires (aside from drought, heat, and wind) has never been determined although arson is suspected in several cases.

Large fires in Siberia’s taiga forests are fairly common and seem to be on the increase. The worst summer was that of 2003 when on one day in June satellites recorded 157 fires burning 27,181,000 acres (42,470 square miles) simultaneously. The smoke plume from the fires darkened the skies over Osaka, Japan some 3,000 miles away and soot from the fires was recorded in Seattle, Washington. The fires were mostly set (accidently or intentionally) by illegal timber firms who sell cheap lumber to China.
More recently, the wild fires caused by the remarkable heat wave of July and August, 2010 in western Russia engulfed 280,000 acres (437 square miles) around Moscow and killed at least 60 people.
As of this writing wild fires in Siberia are currently burning at least 520,000 acres (812 square miles) in Siberia. The Siberian Governor, Dmitry Mezentsev, has declared a state of emergency as “the situation appears to be increasingly deteriorating.”

The near record dry and warm spring this year has already led to a number of large wild fires in Switzerland and Italy. It is feared that this summer could produce a repeat of the disastrous wild fires of the summer of 2007 when 3,000 fires burned 670,000 acres (1,046 square miles) in Greece, burning down 2,100 structures and killing 84 people. The flames came dangerously close to iconic and historic sites in Athens, and Olympia.
INTENTIONLLY set fires in the AMAZON BASIN and INDONESIA
Enormous swaths of forest have been intentionally set ablaze over the past 30 years in the Amazon Basin and on the Indonesian islands of Sumatra and Kalimantan (the Indonesian sector of Borneo). Many millions of acres have been burned to clear land for agriculture and settlement in these regions and dwarf the wild fires I list above that have historically occurred in other places around the world. It is, therefore, hard to call these ‘wild’ fires.
