The deadly wildfires in Bastrop, Texas, known as the Bastrop County Complex Fire, began on September 4, 2011.
The fire burned through October 2011 and is remembered as one of the most destructive wildfires in Texas history. Key details about the event include:
Impact: The fire consumed over 32,000 to 34,000 acres, destroyed nearly 1,700 homes, and resulted in the deaths of two people.
Cause: The blaze was ignited by high winds—exacerbated by Tropical Storm Lee—which pushed trees onto power lines, creating sparks that quickly spread through the drought-stricken landscape.
Conditions: The region was suffering from an exceptional, record-breaking drought and extreme heat, which created highly volatile fire conditions.
The 1991 Oakland Hills Firestorm
Timeline: The fire began as a small brush fire on October 19, 1991, in the Berkeley Hills. Although firefighters believed they had extinguished it, Diablo winds rekindled the embers on the morning of October 20, driving a rapidly spreading firestorm into residential neighborhoods.
Impact: The firestorm lasted for three days and was one of the most destructive in California history. It destroyed approximately 3,800 homes and apartment units, caused an estimated $1.5 billion in damages (1991 dollars), and resulted in 25 deaths.
Contributing Factors: The area was experiencing a five-year drought, and a severe freeze in December 1990 had left significant amounts of dead, highly flammable vegetation. The combination of dry fuels, steep terrain, and Diablo wind gusts reaching 65–70 mph created erratic fire behavior that overwhelmed firefighting efforts.
What is a "Diablo wind?"
"Diablo" is a Spanish word meaning "devil." Diablo winds were so-named for the wild destruction they caused in parts of California in 1991. Diablo winds most typically occur over the San Francisco Bay area. Like the more familiar Santa Ana winds, Diablo winds are hot, dry northeasterly offshore 40-mph gusts noted for producing wildfires in southern California and the Baja Peninsula. Santa Ana winds occur most frequently in late fall and early winter and form over the Great Basin. They kick up over high desert elevations, while Diablo winds form in the mountains around the Bay.
What is a drainage wind?
Both Diablo and Santa Ana winds are drainage winds. A drainage wind is also called mountain or Katabatic wind. The term comes from the Greek for "moving downhill." In a Katabatic, or fall wind, gravity sucks high density air down slopes, at speeds that can reach hurricane force. Notable drainage winds include France's Mistral, the Bora of the Adriatic Sea, New Zealand's "Barber" and the Oroshi wind of Japan.
What is a firestorm?
As wildfire spread by forward directional movement, a firestorm, driven by gusting cyclonic winds, is more erratic. It flings embers around, causing fires break out. Firestorms create their own winds which propel the blaze in crazy patterns.
What happened in the 1991 Oakland Firestorm?
On Oct. 19, during the windy season, an improperly maintained brush fire set five acres alight in Berkeley Hills, Calif. Diablo winds with gusts up to 65 mph, caused the blaze to restart and develop into a firestorm. For three days, the fire ravaged a 1,520-acre area.
What was the death and damage toll?
The firestorm, called also the East Bay Hills Firestorm and Tunnel Firestorm (as it broke out near the Caldecott Tunnel), is notorious not for the area of land it covered, but the the damage it caused. Firestorms caused $1.5 billion in damage, burning 3,354 homes and destroying 437 apartment complexes and condominiums. 25 lives were lost in this terrifying and unexpected storm.
How has firefighting changed in response to the 1991 firestorm?
Building construction changed to create safer, fire-resistant structures. Updates were made to firefighting equipment and public address systems. When a brush fire struck in 2008, in the same location, lesson learned from the 1991 firestorm, enabled firefighters to contain the blaze in 90 minutes. The community will also host a twentieth-anniversary memorial tribute.
