It was learned from Shangri-La City in Yunnan Province that the local area mobilized multiple towns and villages to search for the meteorite that fell in western Yunnan on the evening of the 4th, but the search was unsuccessful.

Videos taken by netizens in Dali, Diqing and other places in Yunnan Province on the evening of the 4th showed that a huge meteorite fell on the night of the Mid-Autumn Festival and landed in Shangri-La, causing concern.

According to reports, at 20:07:05 on October 4, Beijing time, an asteroid impact occurred on the earth. The impact location was 40 kilometers northwest of Shangri-La City, Yunnan Province. The explosion yield was equivalent to 540 tons of TNT, which was larger than the tin in 2014.

The Ringler event (450 tons) is slightly stronger.

The official Weibo of the National Seismological Network "China Seismological Network" also confirmed on the 5th that the China Seismological Network recorded a meteorite impact in real time.

According to preliminary analysis, the impact event occurred in northwest Yunnan Province, China at 20:09:44 on October 4, equivalent to a magnitude 2.1 earthquake.

The Propaganda Department of the Shangri-La Municipal Party Committee in Yunnan Province accepted an interview with a reporter from China News Service on the 5th and said that based on the asteroid impact information circulated on the Internet, the city arranged for relevant township personnel to conduct an investigation on the meteorite. So far, no relevant meteorite has been found, and the meteorite may not have been found.

did not fall into the city.

The report on the Internet that fragments of the meteorite have been found is also a misinformation.

The Yunnan Provincial Seismological Bureau announced through its official WeChat account that after the incident, the Yunnan Provincial Seismological Bureau promptly contacted relevant experts from the Yunnan Observatory and learned that the scientific name of the event was a "bolide airburst" event, which was a high-speed moving asteroid that crashed into the earth.

After orbiting, friction occurs with the Earth's atmosphere, exploding in the air, and the remaining parts falling to the Earth's surface.

"Bolide airburst" events are highly accidental and difficult to observe with astronomical instruments, but they are relatively common with the naked eye.

At the same time, preliminary calculations show that the straight-line distance between the epicenter of the Yongsheng magnitude 2.9 earthquake on October 5 and the location where the Shangri-La meteorite fell is about 244 kilometers. There is no direct causal relationship between the two events.
