On what we stand?. Continued Part 2

Thus, in the north-west of Moscow, where in the years 1920-1940 was only observed gully and river erosion, now have developed karst processes that cause surface subsidence. From this accident Khoroshovskoe area. Many of its residents remember the incidents on the streets Kuusinena, Tukhachevsky, Khoroshevskoye highway where houses were destroyed. And it is in this area are located TEP-16, Khladokombinat N7 and several other vulnerable and dangerous industries in the event of an accident.
— Pumping of ground water has broken the balance of nature?
— Certainly. Violation of the natural ways of groundwater migration, the total dry before watering spaces (horizons), the accumulation of water in front created, sometimes crudely, artificial underground obstacles, massive water leaks, increasing the aggressiveness of the chemical composition of the water — all this leads to a weakening of the supporting soil properties, and at certain areas to strengthen the karst processes with all its consequences.
— For some time now some specialists, and behind them, and the media scare Muscovites discovered near the town of large faults and catastrophic consequences of their possible activation. What is the real situation?
— Geophysicists have found that the city is located at the intersection of the foundation blocks at the depth of several kilometers and forming tectonic faults. But it does not follow that these faults that have been active for billions of years ago remain the same today.
Moscow is located away from the main sources of geodynamic activity. Many signs indicate slow, geologically extended displacements and deformations in some areas, as "flow" of the masses, which does not cause disasters.
— The destruction of some monuments of history and culture, probably due to the fact that they are located in areas of "underground danger"?
— In 2002, Doctor of Geological and Mineralogical Sciences, deputy chairman of the Central Counsil Eugene Merkurevich Pashkin carefully studied the degree of deformation of buildings in some areas of the capital and highlighted the area from the southern end of Gogol Boulevard in the direction of the Russian State Library and along the streets of Moss. Other scholars have identified the north-western area, along which are Tver and Leningrad Prospect.
— How, in your opinion, would happen?
— Several years ago, as part of the program "Security in Moscow" specialists of the Institute of Environmental Geoscience made a series of maps in the capital by types of natural hazards. Lots of geological risk for flooding, landslides and karst take a little less than half the area of the capital. On a map of karst manifestations revealed the three most dangerous from this point of view the area. The first runs through the city from the south-west (along the river valley Syetun) through the center to the north-east. The second — from the center to the north-west along the valley of the Moskva River, the third is the extreme north-west sector along the Ring Road.
According to weather experts, the development of the city will further intensification of flooding, particularly in new areas of mass building and developing industrial zones. In the Western, North-Western, Southern and South-Western districts, where extensive development loamy sediments, groundwater rise relative to the current level could be around 7 meters. In general, the year 2010 in Moscow could be flooded already half the size (compared to today's 30-40%).
This means that in the vast expanses deteriorate mechanical properties of soils, increase the accident rate, and with it the cost of repairing homes and communications. Also, due to contamination of underground and surface environment health will be under even greater threat. And when the next Carpathian earthquake shakes (as in 1940 and 1977), many neighborhoods with tall new buildings can not escape damage. No life-sustaining structure, nor the population to this, it seems, is not ready to …
Among other natural processes provoked by human activities, can be called landslides (usually on the steep banks of the Moskva River, for example, on the Sparrow Hills or in Fili) and the accumulation of explosive methane in the basements of houses on the site of intersection nodes permeable zones in the crust.
All of these processes need to study in detail, we also often limited to what is "written off" on their inability or failure to understand the true causes or technological and operational disturbances and failures. At a time when not respected or violated safety regulations, technology standards, is not taken into account in the design of possible adverse processes, building not regulated and controlled, and the city's infrastructure is complicated, is it any wonder that the number of accidents increases exponentially. — The city will grow up and go deep into the ground. But will respectively grow and deepen our knowledge and engineering solutions in the field of security?
— These things depend, in practice, not from scientists but from the authorities …
Work in the capital of environmentalists is unbroken. The main thing is how you react to the conclusions of experts townspeople. Here is a characteristic quote from a newspaper (large on the front page): "It is hoped that scientists' predictions are exaggerated."
Hope, of course, you can. But not on the failures of scientists. And not for the traditional Russian "maybe blow over." Hope you just have to own — an active and constant for each in its place — counteracting the risk.
