Earthquake online monitoring. Seismically active areas of Russia: where earthquakes are possible

Today it is no longer a 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 cyclical processes and, as a consequence, global climate change. Increase in activity and frequency natural disasters on a planetary scale accounts for 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 increases, but also the intensity, location, and nature of destructive actions.

Yes, the region special attention For scientific direction climate geoengineering and the entire world community today are two points on different hemispheres globe– Yellowstone caldera in the USA and Aira caldera in Japan. These are two huge ones underground volcano, not standing together 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 is like this global catastrophe difficult to assess.

About this and others critical issues early warning of people about impending disasters, openly stated in 2014 world community ALLATRA SCIENCE scientists in the report “On the problems and consequences global change climate on Earth. Effective ways to solve these problems."

According to official terminology, an earthquake is a vibration of the earth's surface or underground points that are a reflection of the internal geological changes of the planet. The basis for this effect is the displacement tectonic plates, which lead to breaks earth's crust and robes. As a consequence, oscillatory movements, depending on the intensity of the process, may extend to long distances, bringing with it not only a destructive effect on social infrastructure, but also a threat to people’s lives.

This issue is dealt with by a special science – seismology. Several areas are being actively studied, including: deepening the knowledge of what seismic activity is in 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 a 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 monitoring is developing in most countries, regardless of the territory, frequency and threat of earthquakes. 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 areas of high seismic hazard. The action of such a destructive force of nature is fraught not only with an energy disaster, 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 necessary characteristics of tremors are studied - magnitude, location and depth of the source.

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

Active participants of the International social movement ALLATRA has developed the most full map seismic activity, which displays objective data from the world information portals and seismic monitoring stations. Informing the public and awareness about the processes occurring on the planet, their causes and consequences is the main goal of this project.

Today, everyone can observe a significant increase in abnormal weather changes, natural disasters, and cataclysms. The active participation of all people, unification, 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 humans cannot prevent.

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 casualties and destruction in a timely manner, as well as to identify areas of the greatest seismic activity.

The Earth's seismic activity map is physical card planet, which displays areas where earthquakes with a power of more than 4 points on the Richter scale occurred over a certain period of time. The map uses the following symbols: The diameter of the area is proportional to the strength 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

The map of seismic activity of the world allows you to select an area by clicking the mouse button earth's surface. In this case, the selected area will be separately displayed in the window, in which the epicenters of earthquakes are indicated in detail. The online seismic monitor allows you to obtain comprehensive data when selecting any source. The table shows the coordinates of the epicenters and the power of tremors, ranging from 24 hours to 30 days.

The greenhouse effect has tripped
Vladimir Erashov

In recent decades, the greenhouse effect has become the talk of the town; it is blamed for the increase in all earthly disasters. But here's a sensational surprise - THE GROWTH OF THE GREENHOUSE EFFECT AND THE NUMBER OF EARTHQUAKES COINCIDED ONLY UNTIL 2005, THEN THE PATH diverged, THE GREENHOUSE EFFECT CONTINUED TO GROW, WHILE THE NUMBER OF EARTHQUAKES STARTED TO DROP SHARPLY. Moreover, the statistics of earthquakes are as follows, we will present them below, which does not leave the slightest doubt about the presence of the indicated trends. The number of earthquakes on Earth increased significantly until 2005, and then began to decrease significantly. Earthquakes in modern times are recorded by many tracking stations with great accuracy and very scrupulously. From this side, any error is excluded 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 look at earthquake statistics: this statistic obtained after processing (summarizing) 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 in 1974. It has not yet been possible to process all the statistics, it is very labor-intensive, we present statistics for January earthquakes; for other months the picture is similar.
Here are the statistics:
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 before 2005 the number of earthquakes, albeit with minor 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 until 2005 greenhouse effect not connected in any way, it occurred for other reasons, these reasons remain to be determined.
An interesting fact is that 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 still impossible to state unequivocally that these facts are connected with each other, but it is also very unlikely that they coincided by chance. Moreover, short-term surges in the number of earthquakes correlate very well with surges in the Earth’s rotation speed.
From the works of scientist Sidorenkov N.S. It is known that the speed of rotation of the Earth has a very good correlation with the temperature on the Planet; a higher speed of rotation of the Earth corresponds to a higher average temperature - this has been established experimentally over a fairly long period of observations. Then a completely logical question:
Will not a decrease in the speed of the Earth’s rotation be followed not only by a decrease in the number of earthquakes, which has already followed, but also by a decrease average temperature, that is, are they signaling to us these factors about the beginning of the cooling era?
Apparently it’s too early to put an end to this issue, but let’s leave it this question without attention, Russian science has no right, the stakes are painfully 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 out of the blue.
In this regard, I ask readers not to be lazy, but also re-read the article “Transparent Climate”.
Isn't it time Russian science wake up?

The destructive power of an earthquake depends on its magnitude (at the hypocenter, i.e. at the source), the depth of the earthquake source and the distance from the epicenter (the point of projection of the source onto the surface of the earth).

Examples of media reports and explanations of terms:
“According to ***, there, at such and such Moscow time, an earthquake occurred magnitude in the outbreak M=4.3 points on the nine-point Richter scale, at a depth of 15 km from sea level.
The epicenter of the earthquake was located 100 kilometers southeast of the city ***. In the village *** were felt aftershocks by force up to four points, and in the city of *** - three points (on a 12-point scale). According to the latest data, there are no casualties or serious damage. Over the course of a week, 4 earthquakes with a magnitude from 2.3 to 4.3 on the Richter scale were recorded in the indicated area, which were also felt in neighboring regions. According to statistics provided by seismologists, average interval between series of earthquakes with a magnitude of up to four points in this area is approximately *** years."

Or
“An earthquake with a magnitude of 4.3 at the source occurred there. Its epicenter was located one hundred kilometers southeast of the city ***. The depth of the source was 15 km” from sea level.

Or
The four-point earth happened today somewhere.

The magnitude of an earthquake (not to be confused with “strength”, and leave the points alone) - quantitatively characterizes its energy at the source, on a nine-point Richter scale (0-9). Calculated based on the results of measurements by instruments (seismographs) at the seismic stations closest to the epicenter different countries. An earthquake with a magnitude of 6.0 or higher, with a nearby epicenter and a shallow source, is considered strong and can cause significant destruction and lead to casualties among the population, especially if buildings and residential structures are not designed for proper seismic resistance or were built by low-skilled migrant workers, with rough violations of construction norms and rules.

The strength of earthquake tremors (intensity) is a qualitative (felt, visible) characteristic of the degree of destruction and other manifestations on the earth’s surface, in specific point on the surface of the earth. For this purpose, a twelve-point scale is used (1-12) or modified scale Mercalli. They differ little. The real danger comes from tremors with a force of four or more.

Forecast. Before a strong earthquake, a few minutes or even hours later, domestic animals and birds begin to scream and rush about, trying to run away from the house to the street, to hide. The dogs are trying to take their owners and children to a safe place. Cats carry kittens away. Aquarium fish- they are worried, trying to jump out of the water of the aquarium. Rats and mice are running outside from the basements of houses. Wild animals, in advance - several hours or days before the earthquake, leave the dangerous area in packs. Snakes and lizards crawl out of their holes (even in winter, at night and in bad weather), Birds constantly scream, fly in circles for a long time and randomly. Animals and birds lose their appetite, their behavior changes greatly - they, without attacking each other, move away from danger together.

Those who were born, raised and lived (in natural conditions) in earthquake-prone areas have the best sensitivity. The skill lasts a long time. Their reaction is more often selective, only to close (local earthquakes) and dangerous in strength (more than two to four points).

Seismologists and volcanologists use scientific, instrumental forecasting methods and methods early warning: constant monitoring of seismic activity by a network of sensitive sensors, regular measurements and detection of increases in the concentration of helium and radon in the surface air and at depth, etc.

Dependence of earthquake intensity. from the distance to the epicenter. From nearby earthquake epicenters great strength(if a “seven” magnitude strike or higher) - very sharp shocks and impacts, intense shaking are felt, glows and sparks are visible, an underground rumble, crackling and roar of collapsing buildings and falling, broken trees are heard, a sharp increase in wind occurs. At distances of hundreds of kilometers from the epicenter, echoes of an earthquake reach - low-frequency, relatively slow vibrations, wave-like swaying of the earth's surface during the day. The farther away, the smaller their vertical amplitude and longer period(up to a minute or more, at a distance to the epicenter of several thousand kilometers), with the exception of anomalously intense and resonant manifestations at certain distances from the epicenter and along large, deep tectonic faults.

Influence of tidal (gravitational) effects. Seismicity increases - during the new moon and, especially, during the full moon, as well as when the Moon is at perigee (closer to the Earth). There is also a seasonal dependence: in autumn and, especially, in winter, it shakes stronger and more often than in spring and summer.

Geological factor. The greatest damage from an earthquake occurs at rocky outcrops rocks and if they are covered with loose sediments of small thickness, which are thrown up at their base. Safer ground conditions are areas with thick layers of loose rocks. rocks in which the seismic wave weakens and is extinguished until it reaches the earth's surface.

Tsunamis occur if the epicenter of the earth is located near the sea coast. At the first impact, the water first moves away from the shore, and then, accelerating, in the form big wave hits the coast. The brightness of the glow of marine organisms increases sharply two to three minutes before the tsunami.

Scientists have compiled a map of the largest tectonic plates:

• Australian;
• Arabian subcontinent;
• Antarctic;
• African;
• Hindustan;
• Eurasian;
• Nazca Plate;
• Plate Coconut;
• Pacific;
• North and South American platforms;
• Scotia Plate;
• Philippine plate.

From theory we know that hard shell The earth (lithosphere) consists not only of plates that form the relief of the planet’s surface, but also of the deep part - the mantle. Continental platforms have a thickness from 35 km (in flat areas) to 70 km (in mountain ranges). Scientists have proven that greatest thickness has a plate in the Himalaya zone. Here the thickness of the platform reaches 90 km. The most thin lithosphere is located in the ocean area. Its thickness does not exceed 10 km, and in some areas this figure is 5 km. Based on information about the depth at which the earthquake's epicenter is located and the speed of propagation seismic waves, calculations are made of the thickness of sections of the earth's crust.

The map shows the locations of seismically hazardous zones. The zones are highlighted in color - from green to red. The closer the color is to red, the higher the likelihood of strong and destructive earthquakes. The map was created using data from earthquakes that occurred since 1973.
Nuclear power plants are shown on the map. Finding nuclear power plant in seismically danger zone increases the danger to the population.

The vast majority of earthquakes last about one, rarely more than one minute. However, the intensity of the oscillations during this time is not the same. As a rule, an earthquake begins with relatively weak vibrations (sometimes imperceptible), which last 10-20 seconds, then the main phase of the earthquake begins, in which the vibrations reach their greatest intensity, then a gradual decline follows. Well-constructed and well-maintained buildings, which do not have special anti-seismic measures, can withstand earthquakes of up to magnitude 6 without much damage. Buildings in unsatisfactory technical condition and dilapidated, under threat strong earthquakes doubly dangerous. Before the earthquake Inside your home, firmly attach cabinets, shelves, and cabinetry to the walls and floors. Furniture, standing and hanging objects in residential premises are placed so that if they fall, sleepers will not be injured and the passages and exits from the apartment will remain free. All heavy objects should be moved to lower shelves and places. Shelves with dishes must be closed. Attach chandeliers and overhead lights securely; do not use glass shades. Do not block passages and exits from rooms and apartments with things. Flammable, caustic, toxic liquids and powders must be securely sealed, closed in strong, secured containers and boxes. All family members should be well aware of the most important dangerous places residential premises: in the openings of internal main walls near these walls, at supporting columns and under frame beams, in the corners of internal main walls and under durable furniture (tables, beds). And dangerous places too: near large glazed openings and partitions, corner rooms of buildings, especially the top floors. During an earthquake Don't panic! Quickly focus on executing previously thought-out actions, but be prepared to act according to circumstances. In the house/apartment: If you are in a low building, up to 2-3 floors, then it is better to leave it quickly. Moreover, this should be done if the building is not earthquake-resistant. Run out quickly but carefully, beware of falling objects, downed wires and other sources of danger, and immediately move away from the building to an open area. When on the upper floors of a multi-story building, do not rush towards stairs or elevators. Most likely, they will be crowded with people and the elevators will be disabled. Therefore, it is better to stay in the building and, after opening front door, which in the future may become jammed from distortions, quickly take the safest place in the room: under durable furniture, at the supporting column wall closest to the center of the building, in the doorway of the main walls, in the corner of the room. And always away from windows, heavy objects and equipment that could tip over. Provide assistance to the disabled and elderly. Do not enter or run around buildings. Once near a tall building, stand in the doorway, this will protect you from falling pieces of glass, balconies, cornices and parapets. It is best to be in an open place, away from buildings and power lines. In transport Any vehicle must be stopped calmly and quickly, as far as possible from tall buildings, overpasses, bridges, power lines or anything that could collapse from strong shocks. Drivers of buses and trams, having stopped transport, must open all doors. After the earthquake While in the building, remain calm and assess the situation. Examine yourself and the people nearby, and if necessary, provide medical care those in need. Wear sturdy shoes to avoid damaging your feet from splinters and debris. When going down the stairs, check the reliability of its structures. Check for fire hazards. Any fire that occurs must be extinguished immediately. If you notice damage to electrical wiring, turn off the power if you have not already done so.
