The greenhouse effect stumbled
Vladimir Erashov

In recent decades, the greenhouse effect has become a byword, it is blamed for the growth of all earthly cataclysms. But here's a sensational surprise - THE GROWTH OF THE GREENHOUSE EFFECT AND THE NUMBER OF EARTHQUAKES COMEDIATED ONLY UNTIL 2005, THEN THE WAYS DIFFERED, THE GREENHOUSE EFFECT CONTINUED TO GROW, THEN THE NUMBER OF EARTHQUAKES STARTED TO DECREASE SHARPLY. Moreover, the statistics of earthquakes is as follows, we will give it below, which leaves no doubt about the presence of the indicated trends. Until 2005, the number of earthquakes on Earth increased many times, and then it also began to decrease many times over. Earthquakes in the present times are recorded by many tracking stations with great accuracy and very scrupulously. From this side, any error is ruled out in principle. Consequently, the indicated trend is an indisputable fact, a fact that allows us to look at the problem of climate warming in a very unconventional way.
First, let's give the statistics of earthquakes, this statistics was obtained after processing (summing up) the daily number of earthquakes stored in the archive of the site http://www.moveinfo.ru/data/earth/earthquake/select
Let us clarify that the site stores earthquakes of magnitude four and above, starting from 1974. It has not been possible to process all the statistics yet, it is very laborious, we present the statistics of January earthquakes, for other months the picture is similar.
Here are the stats:
1974 -313, 1975-333, 1976 -539, 1977 – 323, 1978 – 329, 1979 – 325, 1980 – 390, 1981 -367, 1982- 405, 1983 – 507, 1984 – 391, 1985 – 447, 1986 – 496, 1987 – 466, 1988 – 490, 1989 – 490, 1990 – 437, 1991 – 516, 1992 – 465, 1993 – 477, 1994 – 460, 1995 – 709. 1996 – 865, 1997 – 647, 1998 – 747, 1999 – 666, 2000 – 615, 2001 – 692, 2002 – 815, 2003 – 691, 2004 – 915, 2005 – 2127, 2006 – 971, 2007 – 1390, 2008 – 1040, 2009 – 989, 2010 – 823, 2011 – 1211, 2012 – 999, 2013 – 687, 2014 – 468, 2015 – 479, 2016 – 499.
And so in 2005 there was a radical change in the number of recorded earthquakes, if until 2005 the number of earthquakes, albeit with small stops, only grew, then after 2005 it began to steadily decline.
Main conclusion:
The catastrophic increase in the number of earthquakes that occurred on Earth before 2005 is in no way connected with the greenhouse effect, it occurred for other reasons, these reasons have yet to be clarified.
An interesting fact - in 2005, in parallel with the increase in the number of earthquakes, a radical change occurred in the speed of the Earth's rotation, the Earth began to slow down its rotation. Now it is impossible to unequivocally state that these facts are connected with each other, but it is also very unlikely that they coincided by chance. Moreover, short-term bursts in the number of earthquakes correlate very well with bursts in the speed of the Earth's rotation.
From the works of the scientist Sidorenkov N.S. It is known that the speed of the Earth's rotation has a very good correlation with the temperature on the Planet, a higher speed of the Earth's rotation corresponds to a higher average temperature - this has been established experimentally over a fairly long period of observations. Then a perfectly logical question:
Will the decrease in the Earth's rotation speed not only be followed by a decrease in the number of earthquakes, it has already followed, but also by a decrease in the average temperature, that is, do not these factors signal us about the beginning of an epoch of cooling?
Apparently, it is too early to put an end to this issue, but Russian science has no right to leave this issue unattended, the stakes are too high. Of course, no scientist will cancel the future cooling of the climate, which may be about to begin, but this cooling should not fall on Russia like snow on its head.
In this regard, I ask readers not to be lazy, but to re-read the article “Transparent Climate”.
Isn't it time for Russian science to wake up?

Today it is no secret to anyone that on all continents of our planet there is a significant increase in cataclysms and natural disasters, which are associated with cosmic cyclic processes and, as a result, global climate change. The increase in activity and frequency of natural disasters on a planetary scale falls on seismic activity. Scientists around the world are concerned about the constantly changing data on the increase in the number of earthquakes. Not only their number is growing, but also the intensity, location, nature of destructive actions.

So, the area of ​​special attention for the scientific direction of climate geoengineering and the entire world community today are two points on different hemispheres of the globe - the Yellowstone caldera in the USA and the Aira caldera in Japan. These are two huge underground volcanoes, standing at the junction of lithospheric plates. According to scientists, the activation of one of them can lead to the subsequent activation of the other, and this is not only a large-scale eruption, but also earthquakes, tsunamis and other consequences. The scale of such a global catastrophe is difficult to assess.

This and other important issues of early warning of people about impending cataclysms were openly stated in 2014 by the world community of ALLATRA SCIENCE scientists in the report “On the Problems and Consequences of Global Climate Change on Earth. Effective ways to solve these problems.

Earthquake.

According to the official terminology, an earthquake is a shaking of the earth's surface or underground points, which are a reflection of the internal geological changes of the planet. This effect is based on the displacement of tectonic plates, which lead to ruptures of the earth's crust and mantle. As a result, oscillatory movements, depending on the intensity of the process, can spread over long distances, bringing with them not only a destructive effect on social infrastructure, but also a threat to people's lives.

This issue deals with a special science - seismology. Several areas are being actively studied, including: deepening in knowledge of what seismic activity is in its essence and what it is connected with, possible forecasting of these natural disasters, for timely warning and evacuation of people. Like any other science, seismology can actively develop only in mutually beneficial symbiosis with other sciences (physics, history, biology, geophysics, etc.), since the fundamental basis for all knowledge on our planet is, of course, common.

Seismic activity online and in the world.

Seismic monitoring is developing in most countries, regardless of the territory, frequency and threat of earthquake development. In addition, a seismic monitor is one of the fundamental factors in the development and preservation of the integrity of energy industry facilities. Almost every person on the planet today is an active consumer of electricity. Therefore, power plants are located in all countries and on all continents, including the zone of increased seismic hazard. The action of such a destructive force of nature is fraught not only with an energy catastrophe, but also with global environmental problems.

In order to control seismic processes (earthquakes), study them and warn the public in advance about their occurrence, seismic stations are built in designated areas. All the necessary characteristics of tremors are studied - the magnitude, location and depth of the source.

Earthquakes online.

For all people, thanks to Internet technologies, data is also available today: “earthquakes online”. This is the so-called earthquake map, which provide information about tremors around the world around the clock.

Active participants of ALLATRA International Public Movement have developed the most complete map of seismic activity, which displays objective data from world information portals and seismic monitoring stations. Informing the public and awareness of the processes taking place on the planet, their causes and consequences is the main task of this project.

Today, each person can observe a significant increase in abnormal weather changes, natural disasters, and cataclysms. The active participation of all people, unity, mutual assistance and friendship, the prevalence of true moral and spiritual values ​​in society is the key to the survival of civilization in the future.

Every day various areas of our planet are shaken by tremors. An earthquake is one of the natural disasters that cannot be prevented by man.

The only thing he can oppose to the indomitable forces of nature is the achievements of science in the field of forecasting. Systematization and monitoring of seismic activity makes it possible to avoid human casualties and destruction in time, as well as to identify areas of the greatest seismic activity.

Accounting for earthquake sources

The Earth seismic activity map is a physical map of the planet, which displays areas where earthquakes with a power of more than 4 on the Richter scale occurred over a certain period of time. The following conventions are used on the map: the diameter of the area is proportional to the power of the tremors, and the color of the circle indicates the time interval. For example, red areas correspond to earthquakes occurring on the current date or in real time.

Seismic monitor, updated every 20 minutes


red circles - earthquakes in the last 24 hours
orange circles - earthquakes in the last 1-4 days
yellow circles - earthquakes in the last 4-14 days

EMSC and Google Map data

The map of seismic activity of the world allows you to select a section of the earth's surface by pressing the mouse button. In this case, the selected area will be displayed separately in the window, on which earthquake epicenters are indicated in detail. The online seismic monitor allows you to get comprehensive data when choosing any of the sources. The table shows the coordinates of the epicenters and the power of tremors, ranging from 24 hours to 30 days. Also, on the map of the region, seismic fixation stations located in the selected area are displayed.

Earthquakes are a terrible natural phenomenon that can bring numerous troubles. They are associated not only with destruction, due to which there may be human casualties. The catastrophic tsunami waves caused by them can lead to even more disastrous consequences.

What areas of the world are most at risk from earthquakes? To answer this question, you need to look at where the active seismic regions are. These are zones of the earth's crust, which are more mobile than the regions surrounding them. They are located on the boundaries of lithospheric plates, where large blocks collide or move apart. It is the movements of powerful rock layers that cause earthquakes.

Dangerous areas of the world

There are several belts on the globe, which are characterized by a high frequency of underground impacts. These are seismically dangerous areas.

The first of them is called the Pacific Rim, since it occupies almost the entire coast of the ocean. Not only earthquakes are frequent here, but also volcanic eruptions, so the name "volcanic" or "fiery" ring is often used. The activity of the earth's crust here is determined by modern mountain-building processes.

The second large seismic belt stretches along the high young ones from the Alps and other mountains of Southern Europe to the Sunda Islands through Asia Minor, the Caucasus, the mountains of Central and Central Asia and the Himalayas. There is also a collision of lithospheric plates, which causes frequent earthquakes.

The third belt stretches across the entire Atlantic Ocean. This is the Mid-Atlantic Ridge, which is the result of the expansion of the earth's crust. Iceland, known primarily for its volcanoes, also belongs to this belt. But earthquakes here are by no means rare.

Seismically active regions of Russia

Earthquakes also occur in our country. Seismically active regions of Russia are the Caucasus, Altai, the mountains of Eastern Siberia and the Far East, the Commander and Kuril Islands, about. Sakhalin. Earth tremors of great strength can occur here.

One can recall the Sakhalin earthquake of 1995, when two-thirds of the population of the Neftegorsk village died under the rubble of destroyed buildings. After the rescue work, it was decided not to restore the village, but to relocate the residents to other settlements.

In 2012-2014, several earthquakes occurred in the North Caucasus. Fortunately, their centers were at great depths. There were no casualties or major damage.

Seismic map of Russia

The map shows that the most seismically dangerous areas lie in the south and east of the country. At the same time, the eastern parts are relatively poorly populated. But in the south, earthquakes pose a much greater danger to people, since the population density is higher here.

Irkutsk, Khabarovsk and some other large cities are in danger. These are active seismic regions.

Anthropogenic earthquakes

Seismically active occupy approximately 20% of the country's territory. But this does not mean that the rest of the world is completely insured against earthquakes. Shocks with a force of 3-4 points are noted even far from the boundaries of the lithospheric plates, in the center of the platform areas.

At the same time, with the development of the economy, the possibility of anthropogenic earthquakes increases. They are most often caused by the fact that the roof of underground voids collapses. Because of this, the earth's crust seems to be shaken, almost like a real earthquake. And there are more and more voids and cavities underground, because a person extracts oil and natural gas from the depths for his own needs, pumps out water, builds mines for the extraction of solid minerals ... And underground nuclear explosions are generally comparable to natural earthquakes in their strength.

The collapse of rock layers in itself can pose a danger to people. After all, in many areas, voids are formed right under the settlements. The latest events in Solikamsk only confirmed this. But even a weak earthquake can lead to dire consequences, because as a result of it, structures that are in disrepair, dilapidated housing, in which people continue to live, can collapse ... Also, a violation of the integrity of rock layers threatens the mines themselves, where collapses can occur.

What to do?

People still cannot prevent such a formidable phenomenon as an earthquake. And even to accurately predict when and where it will happen, they also did not learn. So, you need to know how you can protect yourself and loved ones during tremors.

People living in such dangerous areas should always have an earthquake contingency plan. Since the elements can catch family members in different places, there should be an agreement on a meeting place after the shocks stop. The dwelling should be as safe as possible from the fall of heavy objects, furniture is best attached to the walls and floor. All residents should know where they can urgently turn off gas, electricity, water to avoid fires, explosions and electric shocks. Stairs and passages should not be cluttered with things. Documents and some set of products and essentials should always be at hand.

Starting with kindergartens and schools, the population must be taught the correct behavior in a natural disaster, which will increase the chances of rescue.

Seismically active regions of Russia place special demands on both industrial and civil construction. Earthquake-resistant buildings are harder and more expensive to build, but the cost of building them is nothing compared to the lives saved. After all, not only those who are in such a building will be safe, but also those who are nearby. There will be no destruction and blockages - there will be no victims.
