Not so rarely happens that in some areas the ground out of land, and sometimes to fail even at home.In this case, the geologists are beginning to discuss some karst failures.What is, in general, is it?Is there in our country such places?
Simply put, it's a sinkhole.It occurs in the case where the ground water washed under some large portion of the void, then thinned base just can not withstand gravity.
And karst holes can be different: some of them do not exceed in diameter and one and a half meters, but more often it happens that the hopper reaches a dozen other meters in diameter.If multiple failures are connected, it may form a giant basin.
If geodesic investigation found that in some place is likely that outcome, then build there something harder coop is strictly prohibited!
Do not assume, though karst holes are only on land: they are much more at the bottom of the ocean.They are called "blue holes".There were many of them millions of years ago, when sea level was much lower.
Generally, such formations on the planet are very common.Despite this, on any person their appearance makes an incredible impression, so many failures regularly bring to the budget of the country where they are located, millions of dollars.
Tourists are drawn to him continuous chain.Thus, karst holes can be very helpful.
For example, in Texas is a huge crater, which is known as the "Devil's Hole".Tourists are not so much afraid of the name and a gloomy view of space as huge flocks of bats, which have long considered this place home.
known karst collapse in Guatemala in 2010, in the capital of the ground left the whole house.At this point, it formed a giant crater with a depth of 60 meters, diameter - 30 meters.
then killed one person.But it was not the first time!So, in 2007 in the same city I have formed a failure.
If you go to Abkhazia, local travel companies for certain employees "betrothed" to you on a tour of Lake Riza.It is exactly the same sinkhole, only filled with water.Generally, in the world there are many lakes that were formed in this way.They are distinguished by regular shape, the small diameter of the water table and a huge depth.Many of these bodies of water near the lake.
should remember also the karst collapse in Buturlino.That's not the name of the remote province of Central Africa, and a small village in the Nizhny Novgorod region.
he became known after one night right on its main street formed a giant crater.Depth of education was "modest" 14 meters, while the diameter of the failure of 40 meters.
Fortunately, the victims managed to completely avoid, as people were evacuated from their homes on their own, feeling the incipient movement of soil.As a result, it suffered only their property: three houses completely disappeared under the ground, and many of the neighboring buildings that day got visible damage.
