Begging for the cause of wildfires in California, USA

In many areas of Southern California in the United States, hundreds of houses have been burned down by fires caused by wildfires, and nearly 30,000 residents have been forced to evacuate. California Governor Schwarzenegger has declared a state of emergency in the fire area.

Mountain fires spread rapidly

Since the night of the 14th local time, Los Angeles and neighboring Orange, Riverside, Santa Barbara and other areas in Southern California have experienced successive fires caused by mountain fires. The fire caused by the fire spread rapidly under the influence of strong winds. Houses in its path were destroyed and residents were evacuated.

About 600 houses have been burned down. The fire department expects that as the fire further expands, the number of burned houses and evacuated residents will increase. California Governor Schwarzenegger declared a state of emergency in Los Angeles County on the morning of the 15th.

The authorities dispatched nearly a thousand firefighters and numerous firefighting aircraft to put out the fire. However, due to strong winds, progress in putting out the fire was slow. The fire also caused the closure of many highways, making it difficult for people to evacuate.

It is not yet clear what caused the fire, but the local high temperature, dryness and strong winds caused the fire to spread quickly. In the northern suburbs of Los Angeles, police began searching a mobile home park to investigate the cause of the fire. About 500 mobile homes in this parking lot were all destroyed in the fire, making this fire the most damaging fire in the history of Los Angeles.

Causing serious air pollution

The California state government warned on the 15th that as wildfires continue to burn in several areas of southern California, local air pollution is "very serious" and has threatened to the health of local residents.

Sam Atwood, spokesman for the California South Coast Air Quality Management Board, said that severe air pollution caused by wildfires is harmful to everyone, and all local residents should close their doors and windows and avoid outdoor activities. The Los Angeles Health Department also ordered schools and sports clubs to stop all sports competitions.

In areas where fires are raging, black smoke obscures the sky, and the diffuse smoke makes it difficult to breathe. Local hospitals report an increase in the number of people suffering from respiratory illnesses in the affected areas.

Endangering the power supply of Los Angeles

A forest fire broke out in the northwest of Los Angeles, the second largest city in the United States, on the evening of the 14th. In addition to forcing about 10,000 people to flee their homes, it also endangered the city's power supply. Antonio Villaraigosa, the mayor of Los Angeles, California, said that the local wildfire near Sylmar has burned many facilities and may damage transmission lines, "threatening the power supply in Los Angeles. We may have to adopt sharded power outage measures."

He called on residents to save electricity and evacuate in time depending on the spread of the fire. "If you wait until the fire is in front of you (evacuate again), it will be too late. The fire may come close in a moment."

Some roads around Los Angeles have been closed.

Sam Padilla, a spokesman for the city fire department, said that high temperatures caused the ground to dry and coupled with strong winds, the fire spread quickly
