Tangshan earthquake

1976 At 3: 42 on July 28th, an earthquake occurred in Tangshan City, Hebei Province, China. The magnitude is 7.8, and the epicenter intensity is VII. On that day 18: 43, an earthquake of magnitude 7. 1 occurred in Luanxian County, more than 40 kilometers away from Tangshan, with the epicenter intensity of 7 degrees. The earthquake happened in an industrial city with dense population and serious losses. Most of the buildings in Tangshan city were basically razed to the ground or seriously damaged. The rails twisted into a snake shape, and a large number of cracks appeared on the surface, as well as water spraying, sand falling and collapse, accompanied by the phenomenon of light before the earthquake. 242,769 people were killed and 16485 1 people were injured. Nearby Tianjin has also been damaged by Ⅶ ~ Ⅶ. The affected areas cover Liaoning, Shanxi, Henan, Shandong, Inner Mongolia and other 14 provinces, cities and autonomous regions, with a radius of about 250 kilometers. The study of focal physics shows that the process of focal dislocation of this earthquake is complicated.

The strong earthquake caused traffic interruption, communication paralysis, water and power cuts in the whole city, and emergency repair of lifeline projects such as communication, water supply, power supply and traffic recovery is one of the most urgent tasks of Tangshan disaster relief. According to this, the central government quickly arranged counterpart support tasks for various professional systems. Posts and telecommunications, railways, transportation, electric power, municipal construction and other departments immediately acted to ensure the smooth recovery and reconstruction of the above-mentioned system projects. The earthquake was in midsummer, the weather was hot, the rain continued, and the human and animal corpses rotted rapidly, and the epidemic situation was very severe. In epidemic prevention, comprehensive measures have been taken, such as surprise treatment, controlling the source of infection, improving the environment, eliminating pathogens, vaccinating and improving the resistance of personnel. The method of combining military and civilian, combining special groups and combining local and foreign countries was adopted to eliminate the epidemic before it happened, creating a miracle that there was no major epidemic after the disaster.

location

History will always remember this coordinate of the earth: east longitude 1 18.2, north latitude 39.6.

Mankind will always remember this historical moment: July 28th, A.D. 1976, 3: 42: 53.8 a.m. Beijing time.

The underground rocks in Tangshan suddenly collapsed! It seems that 400 Hiroshima atomic bombs suddenly exploded in the crust 16 km above the ground!

Lightning and thunder thundered over Tangshan; The wind roared on the earth. In the violent shaking, this industrial city with a population of one million was razed to the ground in an instant.

The whole land of North China is shaking violently.

There was a loud noise of house collapse in Tianjin, and the Australian Prime Minister who was visiting the city was awakened. Beijing is shaking, the Monument to the People's Heroes is shaking, and the thick beams and columns on Tiananmen Gate make a broken "quack" sound.

In China, Harbin in the north, Bengbu in Anhui and Qingjiang in Jiangsu in the south, Dengkou in Inner Mongolia and Wuzhong in Ningxia in the west, and Bohai Bay Island and the northeast border in the east, people in this vast area feel abnormal vibrations. Powerful seismic waves spread all over the earth at a speed and in a way that people can't feel.

The Palmer Observatory in Alaska suddenly sounded a gripping alarm, and Alaska jumped up and down by an eighth of an inch. According to the US National Geological Survey, an earthquake of magnitude 8.2 occurred near Tianjin, about 0/00 mile southeast of Beijing, China, at 39.6 north latitude and 0/8 east longitude.

The Japanese announced that an earthquake of magnitude 7.5-8.2 occurred in China. The epicenter was in Inner Mongolia, 43 north latitude and 1 15 east longitude.

Sweden says an earthquake of magnitude 8.2 occurred in China.

The Royal Hong Kong Observatory announced that an earthquake of magnitude 8 occurred in China, with its epicenter at 39.6 north latitude and east longitude11.1,which is very close to Tangshan.

China, Taipei and central weather bureau said that an earthquake of magnitude 8 occurred in China.

China Xinhua News Agency broadcast the following news to the world on July 28th: Xinhua News Agency1July 28th, 976: At 3: 42 on July 28th, a strong earthquake struck Tangshan-Fengnan area in Jidong area, Hebei province, China. ……

Nature warns that

This seems to be an unpredictable and unstoppable catastrophe, but nature did issue warnings, which made seismologists who collected data again after the disaster feel creepy and thoughtful. However, for "7.28", it was all too late.

1. Terrible fish

According to fishermen in Caijiabao and Beidaihe, fish are crazy. Around July 28, all kinds of fish came up and turned white, which was easy to catch. The fishermen met with unprecedented luck.

Naked children fish with small nets near Qimen River Gate. Fish can catch dozens of pounds of fish in a few hours as long as they jump into the net.

Chen Yucheng of Zhaogezhuang Coal Mine in Tangshan said that on July 24th, the goldfish in his two fish tanks scrambled to jump out of the water, get out of the tank and put it back, but they all screamed.

Huo of Baigezhuang Fish Farm in Tangshan said that on July 25th, there was an uproar in the fish pond, and grass carp jumped around in droves, and some jumped more than a foot above the water. What's even more surprising is that some fish will turn upside down and stand upside down on the water, but they will circle at the fastest speed.

On the sea of Dagukou, Tianjin, south of Tangshan, the crew of the "Changhu" tanker introduced that on July 27th, the jellyfish around the tanker suddenly increased, and groups of small fish swam around in a hurry, put down their hooks, and soon caught more than 100 fish.

2. Flying insects, birds and bats that have lost their "rationality"

The crew of the "Changhu" oil tanker witnessed that on July 25th, the air around the oil tanker creaked, and a large group of dragonflies with dark green wings flew in, perched on the window, mast and ship's side, motionless, and none of them took off. Soon, the commotion on the ship was even greater. A large group of colorful butterflies, native locusts, black cicadas, and many sparrows and unknown birds also flew in, as if it were an unexpected party. Finally, a colorful budgerigar flew in and stood motionless at the stern.

Hundreds of bats were seen flying in the air in broad daylight in Muchang Commune and Xiyingmen Commune on the outskirts of Tianjin.

A member of Xitangtuo Brigade, panzhuang Commune, Ninghai County, southern Tangshan, since July 25th, the old Yan under the beam has been throwing Xiaoyan out of the nest every day. The owner picked Xiaoyan up and was thrown out by the old Yan. On July 27th, Lao Yan flew away with the remaining two Xiaoyan.

On July 27th, members of Qian 'an Township saw dragonflies flying around like locusts. The flight team is 100 meters wide and lasts from east to west 15 minutes or so. Dragonflies buzzed when they flew by, and the momentum was so great that people were dumbfounded.

3. The Great Escape of the Animal Kingdom

On July 27th, people in Wanggaishan, Luannan County, Tangshan saw with their own eyes swarms of mice running in panic. The big mouse ran after the little mouse, and the little mouse bit its tail into a string. Some people were curious and ran after it, but the good-hearted people dissuaded them and said, "Stop fighting, I'm afraid it will send water."

On the morning of July 25th, in Funing County, some people saw 100 weasels, the big ones on their backs and the small ones on their backs, crawling out of the hole in the ancient wall and moving towards the village. When it was dark, a dozen of them wandered under a walnut tree, and five of them were killed on the spot. Others kept wailing and felt afraid of death. On 26th and 27th, this group of weasels continued their activities outside the village, and there was a panic atmosphere.

Sensitive flying insects, large and small birds and animals, took the first step to escape earlier than humans. However, human beings do not realize that this is a warning from nature. They never thought that a catastrophe that would destroy life was coming.
