Why are wildfires suddenly appearing in the U.S. state of California? What can localities do to contain the fires?

Fires can be started by a bad power line, but that's not always the case with California's frequent fires. Most fires are caused by aging electrical wiring, so it's important to pay more attention to what's going on when it comes to electrical circuits. In California alone, there have been nearly 60 fires that have burned more than 400 acres and caused significant injuries and damage to structures. The reason for the high number of wildfires is that Californians are living closer to the forests and the environment has become drier and hotter in recent decades. Since 1985, more than half of the world's extended fire seasons have occurred in the forests of the western United States. The landscape of western North America has changed slowly but dramatically in recent decades: the climate has become warmer and drier, fuels available for wildfires are accumulating, and the wildland-urban interface is expanding. As a concomitant result, wildfires in North America have become more numerous, larger, and more damaging than ever before, both in number and size, over the past three decades, and are tending to continue to worsen as the climate warms.

When a forest fire occurs, if the fire is small, you can use water to pour, soil buried, branches and other methods of fighting in time; if the fire has started, can not be controlled, do not be a hero, be sure to immediately transfer to the refuge, call the forest fire alarm. Transfer to avoid danger, first of all to correctly determine the wind direction, escape against the wind, if you suddenly feel the wind stopped, do not be careless, which means that the wind direction may change, be more careful. At the same time, pay attention to stay away from dense bushes and grass, and look for an open safety zone (open space, rivers, roads, wasteland, cultivated land, swamps, gravel, etc.). Once in the safe zone, quickly remove combustible materials from the surrounding area to eliminate potential safety hazards. Forest fires cause damage to people mainly from heat, smoke and carbon monoxide. Therefore, when evacuating, if there is a water source nearby, you can use soaked towels, clothes, hats, etc. to cover your mouth and nose to prevent smoke suffocation. In addition, the evacuation should pay attention to away from the dangerous terrain, try to fire line on both sides of the rapid evacuation to avoid danger.

You can't carry lighters or matches and other fire sources into the forest, because once used improperly, it will trigger a forest fire, putting yourself in danger. Not allowed to play in the forest area lanterns or burning lanterns, although the lanterns can fly very high, but it is also very easy to be stopped by the branches of the forest, which led to the terrible forest fire! We must cut off the occurrence of fire from themselves, the human factor is a lot of uncertainty, which is far more terrible than natural disasters.
