How did the fires start? Natural and human causes behind the California fires

Investigators continue their efforts to determine the causes behind the catastrophic fires that swept through the state of California, which killed at least 11 people and left massive destruction in thousands of homes and businesses in the Los Angeles area..
With the fires constantly raging and the authorities unable to control them, the question was what are the reasons behind these terrifying fires.
In the Pacific Palisades area, famous for the homes of Hollywood stars such as Jamie Lee Curtis and Billy Crystal, authorities located the ignition point behind a house on Piedra Morada Street, according to what the American Associated Press reported.

This area is located above a valley with dense trees, which contributed to the rapid spread of the fire due to strong winds.

Although lightning strikes are the most common cause of wildfires in the United States, investigators confirmed there have been no reports of lightning strikes in the area. Therefore, investigations focused on other causes, such as intentional fires and problems with utility lines.

John Lentini, an expert in fire cause analysis, says investigations usually focus on pinpointing the exact starting point and examining the causes around it.

The role of utility lines in California wildfires

California laws require utility companies to report any electrical incidents that may be related to wildfires. For example, investigations into the 2017 Thomas Fire resulted in the discovery that Southern California Edison’s power lines were the primary cause, resulting in massive human and material losses..

Regarding the current Eaton fires, Edison reported no electrical anomalies in its lines prior to the fire, but filed a report with authorities out of an abundance of caution..

Other possible causes of fires

In addition to common causes such as lightning and arson, fires can result from various factors such as burning debris, fireworks, and accidental accidents, such as revealing the gender of a child, which in 2021 caused a major fire that destroyed large areas..

Current status of fires

So far, fires are still burning in the Pacific Palisades and Eaton areas, while dry and windy conditions are helping to exacerbate the crisis. “These fires won’t go out until the fuel runs out or weather conditions change,” Lentini says“.
With the continued drought and no rain in the weather forecast, California faces a difficult test in containing these fires and limiting their losses.
Yesterday, Friday, the American authorities imposed a curfew in areas of Los Angeles, California, to protect properties that were evacuated due to the forest fires that swept the region.
Los Angeles Police Chief Robert Luna announced in a press conference on Friday morning that the curfew applies to the evacuated areas affected by the Palisades Fire and the Eaton Fire, and is scheduled to be in effect from 6 p.m. today, Friday, until 6 a.m. tomorrow, Saturday, local time.

“You cannot be in these affected areas. If you are there, you are subject to arrest,” Luna said.
He stated that the curfew allows the police to take action against thieves operating in parts of the city that have been evacuated.
He added, “We are doing this to protect the facilities and homes that residents left because we ordered them to leave.”
At least 10 people have been killed in massive wildfires that have swept through the greater Los Angeles area in recent days.
