30 degrees north latitude mainly refers to the range covered by 30 degrees north latitude fluctuating up and down by 5 degrees. The 30-degree north latitude runs through four ancient civilizations, which is a mysterious and peculiar latitude. Today, there are too many mysterious events that have been illegally explained by science, such as the famous pyramids and Mount Everest, the highest peak in the world. This issue of National Culture takes you to see the mysterious phenomenon that happened in China.

1 and 30 degrees north latitude are high-incidence areas of earthquakes in China since ancient times.

It is reported that Gu Jianhua, a disaster expert from the Seismological Bureau of China, told reporters that 30 north latitude has been a disaster-prone area since ancient times. At 30 north latitude, earthquakes, shipwrecks, volcanic eruptions and air crashes often occur.

According to historical records, there have been four earthquakes of magnitude 8 or above in Tibet, 7-7.9 earthquakes 1 1 times, and 86 earthquakes of magnitude 6-6.9. 1On August 5, 950, an earthquake of magnitude 8.6 occurred in Chayu-Medog, eastern Tibet.

The epicenter of the 8.0 earthquake in Wenchuan County, Sichuan Province on May 12, 2008 was also at 3 1 degree north latitude, very close to 30 degrees. The place where the earthquake hit 30 was destroyed.

2. The Yangtze River suddenly stopped flowing twice.

The geographical range of the Yangtze River is between 28 45' and 33 25' north latitude, which is recognized as 6300 kilometers. At present, it is actually the Yangtze River in China, 62 1 1.3 km. It is puzzling that it suddenly dried up twice in history.

In A.D. 1342, Taixing County, Jiangsu Province (now Taixing City), the Yangtze River water, which has never been cut off for thousands of years, suddenly dried up to the bottom overnight, and coastal residents went down to the river to pick up relics the next day. Suddenly, the river suddenly rose and drowned many people.

1954 65438+1October 13 After 4 o'clock in the afternoon, this strange phenomenon appeared again in Taixing County. At that time, the sky was dim, the river suddenly dried up and the boat on the river ran aground. After more than two hours, the river surged down. ...

At present, some experts believe that the interruption of the Yangtze River is related to the plate movement (the "breathing movement" of the plate), and the place where the interruption occurs may be "temporarily uplifted", so the river is temporarily interrupted, but when the force between the plates is "relaxed", the ground is restored to its original state.

3. The eternal mysterious cave in Anhui.

In the continuous mountains on the south bank of the downstream of Tunxi section of Xin 'anjiang River in Huangshan City, Anhui Province, there are 36 ancient grottoes in the mountains surrounded by streams, with huge space and strange structure, some of which are layered and have holes in the rocks; Some waves are rippling and winding; Some stone pillars soar into the sky, fantastic and mysterious.

There are no murals, Buddha statues or characters in the cave. Among them, the cave named No.35 has a depth of170m and an area of12000m2. Only a few hundred cubic meters of stones excavated are enough to pave a road from Huangshan city to Hangzhou city.

It contrasts with the masterpiece of nature, Huangshan Mountain. Together with the pyramids of Egypt, Bermuda Triangle, Noah's Ark and many other wonders of the world, it happens to be on the mysterious line of 30 degrees north latitude.

The mystery of Huashan Mystery Cave lies in the large-scale manual excavation of the grottoes, and it is in the center of Xin 'an culture, and there is no information record in history. In addition, the mysteries of the excavation age, use, whereabouts and duration of the grottoes and the identity of the diggers are still unsolved.

4. Sichuan's "Sea of Death"

The "Sea of Death" is located in Penglai Town, Daying County, Sichuan Province, also known as the British Dead Sea, which is another magical landscape at 30 degrees north latitude. Its seawater (brine water) comes from the depth of 3000 meters underground, the outlet temperature is as high as 87℃, and the salt content exceeds 22%. Mainly chloride, similar to the "Dead Sea" in the Middle East, it is easy for people to float and not sink in the water.

Seawater is rich in more than 40 minerals and trace elements such as sodium, potassium, calcium, bromine and iodine. Verified by the relevant national authorities, it has obvious physiotherapy effect on rheumatoid arthritis, dermatosis, obesity, cardiovascular and cerebrovascular diseases, respiratory diseases and so on. According to the relevant research data of UNESCO, people floating in the Dead Sea 1 hour can achieve the effect of sleeping for 8 hours.

5. Mengding Mountain in Ya 'an City has a mysterious pattern.

"Do you know the mysterious patterns of Zuo Qilin and Right Warrior on Mengding Mountain?" "There have been similar phenomena abroad. Could it be the footprints left by aliens? " In a famous geographical forum, donkey friends had a heated discussion on the mysterious pattern of Mengding Mountain, among which there were many speeches by experts and scholars. The reporter found the name of Liu Minsheng, a geological expert of Sichuan Geological Engineering Survey Institute.

The reporter then got in touch with Liu Minsheng. It has been confirmed that there is a strange and huge pattern on Mengding Mountain (30 06') in Mingshan County, Ya 'an City near 30 north latitude: a unicorn on the left and a warrior wearing a feather crown on the right! CCTV 10 program "Into Science" visited here and made a series of reports.

It is understood that as long as you use satellite map software, you can see that this pattern covers almost the whole shady side of Mengding Mountain. Liu Minsheng also analyzed the geographical position and structure of the whole Mengding Mountain from the perspective of geology.

Ya 'an is a very special place in geology, which is located at the core of Y-shaped structure in China. The northwest, northeast and south geological tectonic belts just meet in Ya 'an, forming a meeting point. Therefore, the geological structure here is very complicated, which has the basic conditions for the emergence of this special landform. Of course, the reasons for its formation are very complicated, and only after investigation can we draw a scientific conclusion.

6. Poyang Lake "Devil's Triangle"

On April 6th, 1945, the Japanese transport ship "Kobe Maru" with more than 2,000 tons suddenly disappeared (sank to the bottom of the lake) while sailing to the waters of Laoyemiao in the northwest of Poyang Lake, Jiangxi Province, and none of the more than 200 people on board escaped. Later, the Japanese navy sent people to sneak into the lake for reconnaissance. Everyone who went into the water, except Zhao at the foot of the mountain, disappeared mysteriously. After taking off his diving suit at the foot of the mountain, Zhao was frightened and then went insane.

After the victory of the Anti-Japanese War, Edward Bohr, a famous American diving expert, and his party came to Poyang Lake. After months of salvage, they still found nothing. Besides Edward Bohr, several American divers have disappeared here.

Forty years later, Edward Bohr finally revealed to the world for the first time his experience of losing his mind at the bottom of Poyang Lake. He said: "A few days later, my three partners and I searched for Kobe Maru in the waters several kilometers underwater and found no trace.

Where the hell is this huge thing? Just as we continued to search along the bottom of the lake to the northwest, suddenly a dazzling white light flashed not far away and quickly shot at us. There was a sudden violent vibration at the bottom of the calm lake, and there was a loud noise in my ear, and a powerful attraction held us tightly. I was dizzy and white light rolled at the bottom of the lake. My three diving partners drifted away under the attraction of white light, and I struggled to surface ... "

7. The strange fire of repeated harassment

In Jia Zhu Village, Lianhu Township, Poyang County, Jiangxi Province, villagers Zhu Manshan and Zhu Songshan continued to burn for no reason. The fire is red and linear, and it is strange every time it catches fire. Flammable things didn't burn, but flame retardant things caught fire. No matter how big the fire is, it is always put out with a little water.

From March 23rd to April 6th, 1995, there were more than 20 fires with unknown causes in Jia Zhu.

8. Mystery of the Dragon Rack Savage

The mysterious 30 north latitude line connects a series of colorful and breathtaking natural mysteries in the world-Bermuda Triangle, Egyptian Pyramid, Noah's Ark, Sahara Desert, Mount Everest ... The mystery of Shennongjia savage is also strikingly strung in this mysterious latitude.

Shennongjia is located in the western border of Hubei Province, with a land span of10956 ′-1058 ′ and a total area of 31/kloc-5 ′-3175 ′ north latitude.

For many years, a mysterious shadow has been hanging over the hearts of local people in Shennongjia. No one can be sure what this is. People have a name from mouth to mouth, "Savage".

Many places in the world have reported the mystery of savage, but most of them have gradually disappeared. Only Shennongjia often has savage haunts. Perhaps the ecological environment here is more magical, perhaps the humanistic care here is more cordial, or perhaps their care for this enduring home? It is precisely because of their carefulness that the most beautiful scenery on this earth has added some mysterious and magnificent colors.

9. Sanxingdui Civilization

About three or four kilometers away from Guanghan, Sichuan, there are three loess piles that stand out in the Chengdu Plain, hence the name Sanxingdui. 1929 In the spring, local farmer Yan Daocheng found a beautiful jade pit while digging a ditch next to his house, which opened the prelude to the study of Sanxingdui civilization. 1986, the discovery of two large sacrificial pits in the Shang Dynasty in Sanxingdui, containing thousands of rare treasures, caused a sensation in the world and was hailed as the "ninth wonder" in the world.

Where does Sanxingdui culture come from? A large number of bronze figures and animals here do not belong to any category of Central Plains bronzes. Incredibly, there is not a word left on the bronze ware.

10, the most violent tide: Qiantang River spring tide

Qiantang river tide, also known as haining tide, is a tidal bore at the mouth of Qiantang river in Hangzhou Bay, Zhejiang Province. One of the world-famous tidal bore is also one of the largest astronomical tides in the world. Watching autumn tide in Qiantang has become a custom as early as the Han, Wei and Six Dynasties, especially in the Tang and Song Dynasties. International geographers call Qiantang River, Amazon River in South America and Ganges River in South Asia "the world's three strong tidal rivers".

Qiantang River Borehole is located in Qiantang River Basin, Zhejiang Province. Due to the tidal force of the moon and the sun, the ocean surface fluctuates periodically.
