In Ufa are ground motion

According to scientists, to blame the karst cavities and active construction.

— I jumped out of bed, feeling a strange vibration, look, and the floor was shaking walking! — Told "Komsomolskaya Pravda" resident of the house on Revolutionary, 58 Vladimir Rabinovich. — It lasted around half an hour at night and in the morning again started — cracked ceiling!

Here's a restless night was the last year the residents of a house in the center of Ufa. They felt like heroes Hollywood blockbuster about the end of the world. Earth literally start to go from under their feet.

However, it appeared that the "shaking" to Ufa is no rarity. And it is connected with a large number of underground cavities.

All my fault GROUNDWATER?

At home we are building correctly, but sometimes it happens that the action of an unknown force on them "run" cracks, the floors go shake and death frightened residents running out of them away. And myths are born that Ufa is built over a huge void. And sooner or later we are all at risk of falling into a huge hole.

There is some truth, few people know that in Ufa from 1963 to 1995 was 22 cases of destruction of buildings, including many high-rise buildings. Cracked and broke the house down the street Nejinskaya, 5, and Karl Marx, 43. In 2011, the house number 4 on the street Antonov cracked exactly in the middle. At various times, cracked home the streets were covered with tram, Vladivostok, Mendeleev, revolutionary. In spring 2011, there was a crack in the second entrance of a nine house number 23 on Gagarin Street. The building cracked from roof to foundation.

— In addition to deformation of buildings in the city, there is another problem — the underground failures, — the "KP" honorary surveyor Russia, Associate BSPU Gennady Turikeshev.

In the spring of 2000, Demski district in Cheboksary alley formed dip depth of 12 meters, with a diameter of 10 meters. In 2001, the land has fallen in the Kirov region, outside Pugachev. Formed a deep pit seven meters.

— A large number of failures in the north-western outskirts of the city along the railroad Ufa-Chelyabinsk is because on one square kilometer natural it has 36 holes and wells. And every year there is formed by one or two new failure — said Gennady Turikeshev. Their generation mechanism is very simple: underground karst processes occur. Underground water is slowly but surely dissolve rocks, because of voids and cracks are formed. And if a building year after year formed a void, then it is likely that sooner or later the house will "dance." And this process — quite natural for our area.


In the middle of the last century, scientists believed that the surface of Ufa rise by 2.9 millimeters a year.

However, in modern times the picture has changed radically. Each year, the capital of Bashkortostan lowered by one millimeter. According to Associate Professor Gennady BSPU Turikesheva, this is due to human activity.

— The weight of the earth's surface constructed buildings starts to fall — explains Turikeshev. — The city has an area built up with high-rise buildings, and there are less populated areas. It turns out that the load varies. Because of it, something in the earth layers and any irregularities stress, which leads to the revival of the old and the formation of new faults — so there are cracks. Because of them, and the deformation of the buildings.

Besides being active in Bashkortostan oil. To where it was before the black gold, pumped water: the pressure between the layers is disturbed, they begin to move, and that's a mini-earthquakes occur

A scientist can only throw up your hands, because the country is still not a single seismic station.

— So it turns out that the science geodynamics in our state Hunted — sadly said Gennady Turikeshev. — In the meantime, there are cracks in the buildings Sterlitamak, Neftekamsk and Meleuz. But in the country a lot of good scientists who could do it, if there was a station. Many phenomena can be prevented — "dancing" of houses we would become less.
