What is the catastrophe in Haiyuan, China?

1920 12 16 A rare disaster in human history suddenly came to Haiyuan, China: an earthquake of magnitude 8.5 occurred, which was even more destructive than the magnitude 8.5 confirmed at that time. The aftershock lasted for three years, making it the largest earthquake in China history and the most terrible earthquake in the world so far. In the second year after the earthquake, the government of China released an explosive figure to the world: 234 1 17 people died in this earthquake in Gansu, accounting for 56% of the total number of people in the disaster area.

Haiyuan, winter in 1920. People entered 65438+ February and 65438+ June. ...

This is a day full of strong blood smell forever in human history.

This winter is particularly cold. It snowed in Haiyuan this morning. In the morning, there was another strong wind blowing in this area. At the moment, the sky is dark, foggy, and there is no light in the sun and the moon, much like the battle before the summer rainstorm. However, the abnormal weather did not arouse people's vigilance, and everyone fell asleep with the joy of abundant snow.

Who would have expected that at this moment, death came knocking at the door!

At 20: 06: 09, a red light suddenly flashed in the thick black fog. The sky is like a thousand guns, and a powerful shock wave swept from the northwest. The government offices, houses, shops and temples in Haicheng Town seemed to be squeezing mud, and all fell to the east with a bang.

The earth jumped up and down wildly, and two stone lions weighing 3 tons in front of the county yamen were thrown a few feet high. Then it swayed from side to side, and the ground cracked a gap with different widths, as if the gods had laid tight encirclement, half of the county was buried underground, and nine times out of ten people were buried. In Haiyuan County, except for a clock and a very short adobe arch kiln, all other buildings were razed to the ground.

After the earthquake lasted for 6 minutes, the roaring shock wave fled to the southeast. ...

At dawn, the messy county town has become a water town again. Black water is everywhere on the ground, some water columns are one person high, the water depth between the broken walls is tens of feet, and the black water is full of human and animal corpses.

A bustling town ended hundreds of years of glorious history in an instant and disappeared painfully!

Not only Haiyuan county was destroyed, but also other parts of the county were devastated, because this terrible earthquake zone crossed the territory of the county at that moment.

Xi Anfu, which was originally larger than Haiyuan County, and Dalachi Town, Jingyuan County, which is also prosperous, were both destroyed at the same time, becoming a dead city that nobody cares about so far.

Because all the people in the villa live in caves, which were dug on heaped-up mountains, people are bored in caves when the mountains roll down. One kiln, one kiln, one ditch, one ditch, and no one can be found anywhere. In the farming village, the violent vertical vibration during the earthquake caused all the houses and kilns to collapse, and only 6 people survived in the village 170 people. Such a high proportion of casualties is unique in the world earthquake history.

In a town in the northwest of the county seat, in a large-scale landslide, all the houses and streets fell down with the mountain and cried. No one can tell how many people died in this tiny place. Many people died, leaving no chicken or dog. Many people's bodies are buried too deep, and they can only smell the rancid smell in the loess after the earthquake, so they can't be dug up.

The Haiyuan earthquake is equivalent to dropping 1200 Hiroshima atomic bombs in an instant, which is equivalent to the continuous destruction of Hiroshima 1200 times! According to the investigation and analysis of seismologists later, the damage degree of this earthquake was even stronger than the magnitude of 8.5 confirmed at that time, because the macro-intensity of Haiyuan dry salt pond, which was the most seriously damaged, reached 12 degree, and the aftershocks lasted for three years. This is the biggest earthquake in China's history and the most terrible earthquake in the world so far!

Because the earthquake is in Haiyuan, it is called "Haiyuan earthquake".

After Haiyuan was instantly destroyed, the powerful shock wave did not seem to be completely released. A long earthquake zone, like an angry dragon, waddled to the sea, climbed China and climbed the earth two and a half times.

It is said that the Great Wall in Wan Li, China is the only man-made trace that can be seen when standing in space overlooking the earth. However, this earthquake caused a 220-kilometer-long fault zone, leaving another obvious mark on the earth.

The breadth of extreme seismic zones is unprecedented. It starts from Guyuan in the east, passes through Xiji, Haiyuan and Jingyuan counties, and reaches Jingtai County in the west. More than 20,000 square kilometers have almost become a no-man's land. Dozens of counties in central, eastern and southern Gansu were all swept away. In addition, eight provinces including Xinjiang, Shaanxi, Ningxia, Shanxi, Suiyuan, Qinghai, Sichuan and Yunnan also suffered large-scale disasters.

Not only that, the whole earth is "swinging" with it. "12 16" not only belongs to the sea source, but also is the anniversary of all mankind. ...

At this moment, people on five continents are dizzy-

Beijing: "The electric light is shaking, which makes people dizzy";

Shanghai: "The clock stops and the lights shake";

Hong Kong: "Most people have a sense of shock";

Vietnam: "The observatory clock in Haiphong has stopped";

Cape of Good Hope in Africa: "The cups and plates in the restaurant fell to the ground with a bang" ...

Is there a worse earthquake in the world? To this end, 96 seismic stations around the world recorded the earthquake at the same time. The earthquake was also recorded on the seismograph in Tokyo, Japan, with a magnification of only 12 times. It also recorded an unprecedented phenomenon in the history of earthquakes: the shock wave of this earthquake circled the earth for two and a half times! What a shocking scientific conclusion!

As the birthplace of the earthquake, the then China government remained silent until the second year after the earthquake, and an explosive figure was announced to the world: 234 1 17 people died in Gansu, accounting for 56% of the total number of people in the disaster area.

As the epicenter of Haiyuan County, 73,604 people died in one county, accounting for more than two-thirds of the actual population of the county. Haiyuan is dead, Haiyuan is no longer Haiyuan.

China is one of the countries with the most earthquakes and the densest earthquakes in Chinese mainland. Since the beginning of this century, there have been more than 200 earthquakes 1, of which110 occurred in China. The Haiyuan earthquake of1920 65438+February 16 is one of them, which can be said to be the largest earthquake in China. Earthquake disaster not only causes huge casualties and property losses, but also brings various economic and social problems, so it is a matter of great concern to all countries in the world.

The people of China paid a high price for the Haiyuan earthquake, and we can learn a lot from it. Our attitude towards earthquake disasters is: first, we are not afraid, we are not afraid of earthquakes, and we are not worried all the time; The second is to take it seriously and take strict precautions. Constantly sum up in the earthquake disaster, understand the earthquake law, constantly improve the level of earthquake prevention and disaster relief, and reduce the earthquake loss to a minimum. In addition, people should be alert to all kinds of abnormal phenomena in nature before earthquakes. There will be signs before the earthquake and various signals will be used to remind people, which is also a lesson we should learn from this great earthquake.
