Life Happiness Road (3) --- suffered from the Tangshan earthquake

Just when the old Liu family was still immersed in the joy of adding a big fat boy, on this day, a very terrible thing happened, the sky shook, this thing not only shook the whole village, but also shook the whole county, but also shook the whole country, the earthquake.

Speaking of earthquakes, I have to say two more words. Earthquakes, also known as ground motion and ground vibration, are a natural phenomenon caused by the rapid release of energy in the earth's crust, during which seismic waves are generated. The squeeze and collision between plates on the earth, causing staggering and rupture at the edges of the plates and inside the plates, is the main cause of earthquakes. The place where the earthquake begins is called the epicenter, and the ground directly above the source is called the epicenter. The place where the ground vibrations of destructive earthquakes are most intense are called polar seismic zones, and the polar seismic zones are often the areas where the epicenters are located. Earthquakes often cause serious casualties, can cause fires, floods, toxic gas leakage, the spread of bacteria and radioactive materials, and may also cause secondary disasters such as tsunamis, landslides, collapses, and cracks in the ground. According to statistics, there are about 5 million earthquakes on the earth every year, that is, tens of thousands of earthquakes occur every day. The vast majority of them are too small or too far away for people to feel; Earthquakes that can really cause serious harm to human beings are about a dozen or twenty times a year; There are about one or two earthquakes that can cause particularly severe disasters.

According to records, the first major earthquake in the history of the world was the magnitude 9.5 earthquake in Chile in 1960, which and the tsunami caused by the earthquake killed tens of thousands of people. The tsunami caused by the earthquake even killed many people in Japan tens of thousands of kilometers away. The intensity of the earthquake can be seen. The earthquake with the largest number of victims in Chinese history occurred in Shaanxi, which is also the earthquake with the largest number of victims in the history of the world, that is, 465 years ago, in 1556 AD, during the Jiajing period of the Ming Dynasty, a major earthquake occurred in Huazhou, Shaanxi Province, with a scale of 8.0 and caused 830,000 people to die.

Earthquakes that people do not feel must be recorded with seismometers; Different types of seismometers can record earthquakes of different intensities and near and far. Thousands of seismic instruments of various kinds are operating around the world, monitoring the movement of earthquakes day and night. The current level of science and technology cannot predict the arrival of earthquakes, and earthquakes will be unpredictable for a long time to come. The so-called examples of successful earthquake prediction are basically coincidences. For earthquakes, what we should do is to improve the seismic resistance of buildings and do a good job of defense, rather than predicting earthquakes.

It turned out that at 3:42:53.8 on July 28, 1976, the Tangshan earthquake that shocked the world occurred. China's seismic network measured a magnitude of 7.8, which is the most tragic page in the history of the world's earthquakes for more than 400 years, equivalent to 400 Hiroshima atomic bombs, which exploded in the crust 16 kilometers from the ground. The sky above TangShan flashed with lightning, thunder shook, the earth shook strongly, the wind roared, and a city of a million people was reduced to rubble and rubble. What a terrible number of 242769 deaths and 164851 serious injuries!

It is rumored that on July 27, 1976, before the Tangshan earthquake, there were many abnormal strange phenomena in the village -

First, the climate is abnormal. Older people say the weather was the weirdest day they've ever encountered. Although it is three volts, the weather should not be so hot - the previous heat is mainly characterized by sweating, and the heat of that day is that the heat energy is held in the sweat glands, which cannot be produced and dissipated; in the past, the hot days, shaking the fan can cool off, finding a shade can escape the heat, that day is not, the fan is shaken out of the hot wind, under the shade is also no cool... The heat of the day made people depressed, manic, and crazy!

The second is the anomaly of the watering hole. There is a large waterlogged pond on the back of Liujia Village, surrounded by water and grass, which is a natural regulator of temperature and humidity in the village, and it is also an "open-air bath pond" for villagers to bathe and cool down in summer. However, on July 27, when people went down to the pit to take a bath, they found that the originally clear pond had become a muddy mud pit. Some of the small fish in the water jumped up from the water restlessly, and some spit bubbles in their mouths and floated on the surface of the water.

The third is animal abnormality. Zhen Bin, who raised livestock for the brigade, unloaded the cart at night, and the cattle refused to enter the shed, how to pull and how to fight, and refused to go to the trough to eat grass. Some cattle, contrary to their old nature, sneezed, sneezed, rolled on the ground, and howled with all their might, as if to express something to the people. But none of this has alarmed people. People often say "play the piano to the cow" the cow does not understand. Nowadays, livestock still do not understand "playing the piano to people". From this point of view, people are dumber than cattle!

Of course, in the early morning of July 28, when the ground was shaking, people woke up from their sleep, not knowing what had happened, when the elderly and knowledgeable people shouted at the entrance of the village that the earthquake had occurred, people realized that it was really an earthquake, and rushed out of the house, crying and shouting, panicking, most people still holding babies, wearing pants, and even more naked standing in the middle of the yard, on the edge of the wheatgrass stack on the barley field, hiding from the disaster.

Early the next morning, the commune's public family organized a survey of the disaster in each village and told the villagers not to stay at home but to take refuge in an open place. In order to take refuge, each family also built a shack in the middle of the barley field and their own yard. The old Liu family is no exception because they are afraid that the newborn grandson will be hurt, they also set up a grass nunnery in the yard, and set up a pot stove in the yard to cook, and they dare not stay at home anymore, for fear of a large aftershock and the collapse of the house.
