Why so many fires?

California is burning! Wildfires have spread across the US State since Oct 23 and smoke has filled its skies.

Take the Kincade Fire in northern California for example. It forced ( 迫使 ) 200,000 people to e 1 its path within one week. The state’s largest power (电力) company cut power to about 206,000 homes in order to s 2 more fires from breaking out, CBS News reported.

California has seen many wildfires in recent years. Nine of the 10 biggest fires have happened since 2000, i 3 five since 2010, according to The New York Times.

Why is this? California has the perfect wildfire c 4 , Park Williams, a US climate expert (气候专家), told The New York Times. It has dry air and high temperatures from spring through late fall. At the same time, seasonal winds blow across the state every year, causing the wildfires to spread q 5 and last for weeks.

Global warming has also made the fires worse in recent years. It has dried out the state’s trees and o 6 plant life, causing them to burn more easily.

H 7 have played a role as well. Burning campfires, garbage debris ( 碎片 ),and cigarette butts (烟头) can easily cause wildfires. For example, one fire started last year when a car got a flat tire (漏气的轮胎). The car’s body met the road and sent out sparks (火花 ), starting a f 8 .

Lightning strikes (雷击) and volcanic eruptions (火山爆发) can also cause wildfires. However, people have caused 90 percent of California’s wildfires, according to the US National Park Service.

More about wildfires

Wildfires often happen in wooded areas in the US, Canada and Australia. They are also k 9 as forest fires or grass fires in Australia.

Wildfires can burn at over 900℃ and reach heights of more than 50 meters. They can move at speeds of up to 23 kilometers an hour, burning e 10 – trees, brush, homes, even people – in their path.

Every year, 12,000 to 14,000 e 1 happen around the world, killing tens of thousands of lives. So when scientists talk about monitoring（监测）earthquakes, every second counts. Recently, a new AI system d 2 by China is shortening the time it will take to detect（探测）earthquakes.

After an earthquake happens, most researchers can quickly release（发布）the time, p 3 , magnitude（震级）and depth of the earthquake. H 4 , they often don’t include the focal mechanism parameters（震源机制参数）, which can be used to predict（预测）the possible distribution（分布）of strong aftershocks（余震）.

“It t 5 three to 10 minutes for other countries to release the focal mechanism parameters, but by this time, the earthquake has fully happened and the h 6 has been done,” Zhu said. “This new system can p 7 the focal mechanism parameters in just one second and release the information before the aftershocks reach some areas.”

“If we are a 8 to receive the warning information three seconds earlier after an earthquake happens, we’ll be able to r 9 the wounded by 14 %. With 10 seconds earlier, the wounded can be reduced by 39%.” Zhu said.

This improvement is possible thanks to a deep learning method. The system is trained with millions of earthquake samples（样本）. It’s now t 10 in Yunnan and Sichuan provinces.
