Seven famous villagers in Sichuan were hacked to death by lightning when they went up the mountain to dig Cordyceps sinensis. Why did they cause such serious casualties?

A lightning strike occurred in Derongma Township, shiqu county, Ganzi Prefecture, Sichuan Province. Seven villagers who were digging cordyceps were killed by lightning. The seven people who died came from two families, including three men and four women, the oldest of whom was only in his thirties, and a child who was taken away by his mother.

According to a local villager, May and June are the time for collecting Cordyceps locally. In the process of collecting Cordyceps, villagers will choose to spend the night in the mountains. There is no signal in many areas of the mountain, so it is difficult to contact.

The staff of Ganzi Meteorological Bureau told the reporter: "Due to the high altitude, about 5,000 meters, extreme weather is more common. No one was struck by lightning before the incident. We are still continuing to verify the relevant situation of this incident. "

It is reported that shiqu county is located at the southeast edge of the Qinghai-Tibet Plateau, at the junction of Sichuan, Qinghai and Tibet provinces, with an average elevation of 4,526 meters and an average elevation of 4,265 meters, making it the largest and highest county in Sichuan Province.

According to statistics, about 4,000 people around the world are struck by lightning every year, and the average probability of being struck by lightning is about 1.75 million. It is unusual for a person to be struck by lightning with such a small probability. Why were seven people killed by lightning in shiqu county at the same time?

According to local people's speculation, the biggest possibility is that digging Cordyceps requires metal tools such as hoes, which is easy to attract lightning in the wild, and seven people were very close at the time of the incident, which led to the tragedy of all deaths.

Lightning is a discharge phenomenon caused by the interaction of positive and negative charges in clouds. The average current is about 30,000 A, the highest current can reach 300,000 A, the voltage in the sky is about 65.438+0 billion ~ 65.438+0 billion V, and it will reach tens of thousands to hundreds of thousands of volts near the ground. The voltage that our human body can bear is 36 V, and the alternating current used in daily life is 220 V, which can't be compared with lightning at all.

In addition to strong voltage and current, the instantaneous temperature around lightning may be as high as 30,000 degrees, which is close to 5.5 times the surface temperature of the sun (5,500 degrees).

In the face of the magnificence of nature, human beings are always small, so outdoor activities should be avoided as much as possible in thunderstorm weather, and urgent and important things can be done after the rain stops. After all, nothing is more important than your own life, isn't it? A gentleman does not stand under a dangerous wall. Be sure to pay more attention to weather changes and forecast information before going out, plan your trip in advance, and try to avoid going out in thunderstorm weather!
