Videos from China, the starting point of the coronavirus epidemic, and posted on social networks have been about Kovid-19 for a long time. However, after a strange incident yesterday, China is on the agenda for a completely different issue and panic.
Located in Shenzhen City, Guangdong Province of China, SEG Plaza is a 79-story skyscraper nearly 300 meters high. Built in 2000, this skyscraper is also the address of major electronics companies and many offices operating in the country.
The incident that made the headlines of this skyscraper in the world press is an incredible video posted on social media.
In the video shared on social media, the 79-story SEG Plaza building suddenly begins to shake right where it is, for no reason. At that time, as people in the building were trying to panic out, the pedestrians on the street where the skyscraper was located also notice the situation and start to flee in fear.
Of course, the first thing that comes to my mind is that there is an earthquake in the area. However, what is strange is that there were no earthquakes recorded in the area at the time of the incident! It is known that multi-story buildings oscillate when it comes to strong winds, that is, they tremble like an earthquake. But at this time, the wind speed blowing in the area is only 43 kilometers per hour. So it is not with gravity that can cause this.
The skyscraper was evacuated after the incident at 1:00 p.m. yesterday. When the clock read 2:30 p.m., the building was completely sealed from danger and entry was not allowed.
As emergency officials quickly arrived in the area, experts began to investigate the causes of the incident.
According to a theory put forward by an engineer named Lu Jianxin in a press release, this strange phenomenon can be caused by the extremely rare occurrence of a natural oscillation of a structure coinciding with mechanical resonance due to an external effect. According to Jianxin, since no earthquakes have occurred in the area, the most logical explanation is some kind of “random frequency” phenomenon.
However, the cause of this rare event remains a mystery.
