Why were seven tourists struck by lightning while sheltering from the rain at the beacon tower?

20 17,10 On the morning of September 20th, there was a sudden shower in Huangyaguan Great Wall Scenic Area in Tianjin, accompanied by lightning and showers. As the rain came in a hurry, the tourists on the Great Wall failed to get down in time, so they had to run to the nearest enemy building to take shelter from the rain. At about 1 1 20, some tourists who took shelter from the rain in the watchtower 16 were struck by lightning, causing seven people to be injured to varying degrees.

It is understood that at the time of the incident, when they climbed to the Huangyaguan Great Wall 16 beacon tower near the top of the mountain, it suddenly rained heavily, and several people hid in the beacon tower to avoid the rain. At about 1 1 point 30, a lightning strike hit the beacon tower.

A tourist said, "I sat on the ground after being struck by lightning." Although I was not directly knocked down by lightning and my body was not burned, I felt weak in my legs and feet, and my heart was particularly uncomfortable. I sat there for a long time before I came to my senses. "At this time, he found a 1 1 year-old girl, the girl's father and a middle-aged man were knocked to the ground by current, and three people were unable to speak or stand because of serious injuries. Middle-aged man, head down, bleeding profusely. In desperation, the tourist quickly called the police for help.

Because the beacon tower is far away from the gate of the scenic spot and the Great Wall is steep, it took rescuers more than half an hour to arrive at the scene. Rescuers told reporters: "After we arrived at the scene, there were only four people on the scene, three of whom were seriously injured, 1 person was slightly injured, and the other three tourists were not seriously injured. The lightly injured tourist is a girl of 1 1 year old, and her mood is very unstable. We have been comforting her. "

Three seriously injured people were carried away from the scenic spot by stretchers, and the other four tourists were escorted to the parking lot by rescue teams. The 120 ambulance that had arrived immediately sent the injured to Jizhou County People's Hospital for treatment.

At present, of the seven injured, four need to be hospitalized for observation, and the other three have been discharged, which is no serious problem.

The reporter interviewed a staff member of lasg about the lightning strike on the beacon tower. The staff member explained: "Although the beacon tower is equipped with lightning rods, it is not absolutely safe. It is most likely that this matter was caused by a mobile phone. Electromagnetic waves will form a conductive magnetic field in a humid atmosphere, which is very easy to attract new lightning strikes.

Thunderstorm weather, lightning interferes with the ion fluctuation in the ionosphere of the atmosphere, and the wireless frequency hopping of the mobile phone is enhanced, resulting in the chip being burned or the lightning being led to the mobile phone. But generally speaking, there are lightning protection devices in public residential areas, and people are relatively safe in this environment. Thunder and lightning will only interfere with the mobile phone signal, damage the chip at most, and will not cause fatal harm to the human body. Once in the open area, people and mobile phones will become obvious bumps on the ground, and mobile phones are likely to become the discharge objects of Lei Yun's choice. "
