Berliner Tageszeitung - California's largest fire of year rages in state's north

The so-called Park Fire outside of Chico in the state's north has been raging since Wednesday in a rural region about a three hours' drive northeast from San Francisco.

It has now ravaged more than 370,000 acres (149,700 hectares) according to the Cal Fire agency, making it one of the largest fires in state history.

No casualties have been reported so far, and firefighters benefitted from a slight drop in temperatures over the weekend which allowed them to make a bit of progress, with the fire now 12 percent contained.

Nearly 4,900 firefighters have been mobilized, with 33 helicopters, 400 fire trucks and numerous planes battling the conflagration.

Meanwhile, about 4,200 residents are under evacuation orders, and authorities are calling for the utmost caution due to the situation's risk of escalating at any moment.

"We ask that the public continue to be diligent and prepared due to erratic fire activity," Cal Fire said.

The megafire progressed during the first 48 hours at the speed of a person walking and has spawned fire tornadoes as well as generated smoke clouds shaped like atomic mushrooms.

- 'Super, super dry' -

The fire was able to spread quickly following multiple heat waves that have struck California and the US West since the beginning of June.

Vegetation "is still super, super dry," said Daniel Swain, an extreme weather specialist at the University of California, Los Angeles, adding that it was caused by "a month of record-breaking heat and evaporative demand."

While the foothills of the Sierra Nevada Mountains burn regularly, there hasn't been a fire for decades in the forests where the Park Fire is located, meaning there is plenty of fuel for the flames.

Despite the massive resources deployed by California, which has special expertise in firefighting, "it's still beyond technology to address a fire at that scope," Swain said.

The enormous Park Fire brings back bad memories: the town of Paradise, where 85 people died in 2018 in the deadliest fire in state history, is only about 12 miles (20 kilometers) from the flames. Its residents have already been put on alert.

In the meantime, some inhabitants of evacuated towns have chosen to stay until the last minute, such as Justin Freese, who is waiting with a firehose and 10,000 gallons of water at the ready.

"I'm prepared, but I'm not stupid," he told the New York Times. "If there's a 100-foot wall of flames coming, I'm not going to stay put and melt my skin."

- Multiple fires -

The Park Fire was caused by arson, according to authorities. A 42-year-old man was takin into custody Thursday morning after being spotted pushing a burning car into a ravine, according to the local prosecutor's office.

The United States is presently battling about 100 large fires according to the National Interagency Fire Center, mainly in the west of the country and in particular Oregon, where an airplane pilot fighting the fires died last week.

The smoke generated by the fires has prompted the weather service to issue air quality alerts in many places.

In California, a fire that broke out last week nearly razed the historic gold-mining town of Havilah in the state's center over the weekend, but caused no casualties.

Repeat heat waves and extreme weather events are accelerated by climate change, which is linked to humanity's reliance on fossil fuels, according to scientists.
