In the Kursk, Belgorod and Orel regions, the Kursk Magnetic Anomaly (KMA) is located. This is the largest region on our planet, which is incredibly rich in iron reserves.
Back in 1773, the astronomer P. B. The pacers noticed that under the city of Kursk the compass, namely its magnetic needle, behaves strangely. In this abnormal area, the compass can show anything: it begins to point east, although there is west, it confuses north and south.
Later, in 1874, privat docent I.N. Smirnov decided to conduct a geomagnetic survey of the European part of Russia, and was surprised to find this anomaly.
The scientist N.D. solved the riddle. Pilchikov, who observed the KMA and suggested that it arose due to the large deposits of iron ore in the area. For this discovery, he received an award - a silver medal. Later, the first deposits were discovered here, and ore mining began.
KMA - these are two underground iron ore ridges. One stretches for 400 km, has a width of 25 km, the other - 600 km in length and 30 in width. It is this gift of nature that feeds the local population in recent years.
We recommend you 10 interesting facts about the Kursk magnetic anomaly - one of the most unusual places on Earth.
10. The largest iron ore basin
One of the largest iron reserves in the world is KMA. Only explored, i.e. the reserves of rich ores known to us are 30 billion tons, which is a lot, given the fact that world iron ore reserves are 160 billion tons. This is the largest iron ore basin known to us in Russia and around the world..
9. The total area of reserves is about 160,000 km²
Iron ore in this area has captured a huge area, covers an area of over one hundred and sixty thousand km². The Kursk magnetic anomaly includes 9 regions of our country, mainly the South and the Center.
8. In 1773, the first to notice the "strange terrain" pacers
Peter Borisovich Inokhodtsev was once one of the best students, on the initiative of M.V. Lomonosov was sent abroad for further training, showed himself as a brilliant specialist. He became a famous scientist, astronomer.
He headed the expedition, which was supposed to determine the latitude and longitude of some cities, including Kursk. There he noticed the strange behavior of the magnetic needle.
7. In 1923, the first ore mining was carried out.
The famous Russian geophysicist, Professor Ernest Leist, was sure that large iron deposits were located at the KMA location. But geologists did not share his point of view, because it seemed unbelievable that in a flat place ore deposits could appear that would exceed in their reserves all other deposits on our planet.
A real “fever” began, many land owners sold and bought land in this place. Leist was given money to purchase the necessary equipment.
The scientist calculated that the iron ore deposits are not very close to the surface, at a depth of two hundred meters. But in the place he chose, she was not found. They ceased to trust his conclusions, but Leist himself was sure that he was not mistaken, and did a great job of studying the Kursk magnetic anomaly.
He took all the documents with him, going to Nauheim for treatment, but he died there, and the Germans appropriated his studies to resell the USSR. Lenin himself ordered P.P. Lazarev to conduct a new survey of this area. And in 1923, near the village of Lozovka, the first samples of such coveted ore were discovered.
What is the most annoying, not far from the first Leista well, it was also found, but at a depth of 220 m, i.e. even a little bit, and the work of his life would be appreciated. The first mine appeared in this area in 1931, in the Starooskolsky district.
6. Weak immunity of local residents
Back in the late 80s, specialists at Kursk Medical University were the first to notice that the incidence of infectious diseases at the site of the anomaly is several times higher than in neighboring cities.
Studies were completed that completed in 2007. They found that geomagnetic field weakens immunity and creates favorable conditions for the spread of infectious diseases. As it turned out, this is due to the fact that the immune system is constantly experiencing overstrain, and if a person becomes ill, it is more difficult to cope with the malaise. This is on the one hand.
On the other hand, the Kursk magnetic anomaly, on the contrary, supports microbes. The causative agents of dysentery and salmonellosis in this zone have been studied. Scientists were able to establish that they have an increased ability to cause disease and have resistance to drugs. Therefore, the disease is more difficult and long.
Experts advise taking immunostimulants and monitor your health. Nothing more can be done, because it is impossible to eliminate the intensity of the geomagnetic field.
In Zheleznogorsk, as scientists have established, pregnancy pathologies are more common and the course of sexually transmitted diseases is complicated.
5. Scientists have identified the relationship between the terminal and geomagnetic fields
If a person works with terminals, then two magnetic fields seem to overlap each other, terminal and geomagnetic. This leads to sad consequences. Those who live in the anomaly zone and like to sit by the computer are often sick, because they have lower immunity than the rest.
There is no help in this case, because without technology in the modern world can not do. Scientists can only advise taking ascorbic acid, which has a good immunostimulating effect.
4. Low yield of nearby lands
Statistics show that yields in these regions are slightly lower than in farms located in other areas. and similar in soil and climatic conditions, but with a normal magnetic field of the earth. The difference is not very big, only 10-15%, but it is.
3. Legends about the appearance of UFOs in the anomaly zone
Where the anomaly is located, unidentified flying objects are constantly observed. There are many testimonies when in this area UFOs were observed not by 1-2 people, but by more than 10 witnesses.
In 1990, the ufological society “Visit” was organized in the city of Kursk, which recorded 52 cases in the first year of its existence. There are many stories about how residents watched flying objects, as well as how UFOs land.
2. The observation deck at the mine for tourists
In recent years, industrial tourism has become increasingly popular. If desired, you can visit a magnetic anomaly, this can be done by anyone. In many quarries there are museums and information centers, observation platforms have been made. Special groups are organized, local companies offer their tours that are affordable for almost anyone (from 1.5 thousand).
1. In 2004, a stamp with an illustration of KMA was issued
Publishing and Trading Center "Marka" in 2004 decided to issue postage stamp No. 904, which cost 5 rubles. It was a series of “Russia. Regions. " Just printed 200 thousand copies. The artist was Sukharev S., who drew an illustration where we can see the extraction of iron ore at the KMA. In addition, it has a monument to the defenders of the Fatherland and another monument, this time to Prince Vladimir.
