“Among the most notorious California wildfires, the Bel-Air/Brentwood fire began in a trash heap…..a blaze that left hundreds of the rich and famous homeless in what LIFE magazine called ‘A Tragedy Trimmed in Mink’ and prompted brush clearance laws and an eventual city ban on wood shingle roofs.”
The brush fire started Nov. 5, 1961, and blackened more than 16,000 acres. Santa Ana winds fanned the flames.

Researchers this week announced a new tool that can take some of the guesswork and resource limitations out of the equation when it comes to estimating wildfire risk.
Investigators with the National Centers for Environmental Information and the NASA DEVELOP National Program collaborated with a series of groups to create the tool that automatically processes satellite and weather station information. The Fire Risk Estimation tool — FIRE Tool for short — takes into consideration temperature, precipitation, relative humidity and wind observations and produces a single measurement of fire potential.
The new tool will be able to process data in almost real-time, determine when indicator thresholds are met or exceeded, and weigh how much each indicator would influence risk. From there, fire managers will be better able to more intently mobilize resources to high-risk areas — a tactic that until now was severely limited due to gaps in available information and computation.
“To create the FIRE tool, the team began with a list of indicators used to assess wildfire risk and the thresholds for each that would indicate higher risk,” researchers wrote in an online piece posted to NCEI. “Provided by fire managers in South Dakota, these initial indicators and thresholds were based on meteorological conditions that accompanied several large, complex wildfires in the past decade.”
Once the overall risk potential is calculated, information is plotted on a color-coded map spanning five categories — low to high.
From the NCEI report:
“This gives fire managers an overall view of risk in different locations, helping them quickly decide when and where to allocate their resources.”
The FIRE Tool was initially built for the Great Plains. However, experts say it can be modified to landscapes and geographical regions across the country.
“Part of the solution to dealing with the increasing complexity of wildfire management is to reduce uncertainties inherent within active fire management, where time-sensitive decisions often rely upon incomplete information. Breaking out of the wildfire paradox requires aligning the short-term operational objectives of incident responders with the longer term ecological and management objectives of landscape planning.”
The session is expected to focus on three specific topic areas. Among them, according to the event’s website:
Using risk-based analysis to quantify the potential hazards and benefits of wildfire to the things we care about.
Developing a network of potential fire control opportunities from characteristics identified from historical fire perimeters
Leveraging these control opportunities and risk assessment outcomes to develop response strategies that align fire operations with landscape planning objectives.

Justin Jager, interagency aviation officer for Grand Canyon National Park, Kaibab and Coconino National Forests and Flagstaff and Verde Valley Area National Monuments, said the drones are utilized in conjunction with traditional methods. Operators use the devices to scout fire lines, or communicate information to other personnel in the area.
The unmanned systems aren’t replacing fixed-wing scouting planes. Rather, they’re being used to search a fire’s outer edges and providing intelligence that can help establish stronger fire lines.
“We’re taking what we’re learning and creating a guide for other agencies, like BLM (Bureau of Land Management) or other national parks to create their own programs,” Jager said. “I think they can all benefit from adding this tool.”
Grand Canyon National Park is the only park with its own fleet of unmanned aircraft that can be used for locating people who have gotten lost, stranded, injured or killed. Under a program that began last fall, it has five drones and four certified operators, the Associated Press reported.
The drones are about 18 inches across and 10 inches high, with a battery life of about 20 minutes. Drone operators watch the video in real time and then analyze it again at the end of the day.
The U.S. Department of Transportation’s Federal Aviation Administration (FAA) has come out in the past supporting the U.S. Department of the Interior and U.S. Forest Service in their simple message to drone operators: If you fly; we can’t.
“Flying a drone near aerial firefighting aircraft doesn’t just pose a hazard to the pilots,” said U.S. Transportation Secretary Anthony Foxx. “When aircraft are grounded because an unmanned aircraft is in the vicinity, lives are put at greater risk.”
That didn’t matter. After a string of incidents last year, the FAA warned in a mass email to recreational drone operators that those “who interfere with wildfire suppression efforts are subject to civil penalties of up to $27,500 and possible criminal prosecution.”

After just one day of deliberation, a jury last week acquitted an Alaska couple on all counts related to the destructive Sockeye Fire.
Amy DeWitt, 43, and Greg Imig, were charged with a dozen counts each related to the 2015 fire. Among them: second-degree negligent burning, burning without clearing the area, allowing the wildfire to spread and reckless endangerment, the Alaska Dispatch News reported. If convicted, they could have faced fines and jail time.
The three-week trial ended Friday when the six-person jury returned “not guilty” verdicts on all counts.
In a prepared statement following the verdict, Imig told reporters the fire was “very costly” for the couple, in both the physical property lost and the price of defending themselves at trial. But he said it was necessary for the “real information” to come out.
“From the beginning, (DeWitt) and I have been forthright and honest and, frankly, this trial by the State of Alaska was wasteful and unneeded,” he read. “We knew we had to take this path to clear our name.”
Defense attorneys and private investigators maintained the state’s investigation was inconclusive as to the fire’s cause. They also cited the Wildfire Origin and Cause and Determination Handbook, arguing state investigators should have better documented the property and taken more steps to allay any “confirmation bias.”
