From August 2011 to January 2013, the noise of the Earth swept the world.

The main feature of the anomaly is to cause panic in people. Until now, scientists cannot understand exactly what this phenomenon is. There are many versions of the origin of the riddle. Nature itself, as well as secret special services, aliens and even the Creator are accused of the acoustic phenomenon. The intensity of passions is also caused by the fact that this natural strangeness began to occur on the eve of the End of the World according to the Mayan calendar. Is what is happening real or did the newspapermen invented another duck for the people?

The largest series of such sounds occurred between January 9-12, 2012. During these days, as the media said, the Earth literally howled. It is noteworthy that in all cases it was impossible to identify the acoustic source. Experts from various industries only gave some versions and we invite you to familiarize yourself with them. Some of them are more believable, and some less. In theories, there was a place for both scientific assumptions and religious ones.

Sounds of the apocalypse

Not only scientists, but also believers paid attention to the groan of the Earth. According to the pious, this may be an omen of the End of the World. In different religions it is said that people will be notified of Armageddon by a certain sound that will be heard in every corner of the planet. In Judaism, it is written that the famous Jericho fell from the acoustics of the shofar trumpet. On the Internet, users quickly processed this idea and came to the conclusion that a kind of play of nature is a consequence of the sound of Jericho trumpets. In addition to the Jewish belief, the noise of the Earth is spoken of in Scandinavian and Germanic mythology. In this case, Ragnarok will announce the End of the World in the golden horn of Gjallarhorn. The Qur'an and the Bible also found a place for the creak of the earth.

The rumble of the Earth: a technogenic theory

Perhaps the most common version. According to geologists, the roar of the planet is due to rock explosions. For example, this kind of detonation can happen during the development of coal deposits. The allegedly released energy bursts out, causing either an earthquake or a mysterious phenomenon. A similar anomaly can occur in a place where many high-voltage transmission lines are stretched. If the frequency in the power supply system reaches 60 Hz, then this indicator will be enough for a "short circuit" to form. But this assumption has a drawback. If the "production" factor was the cause of the mysterious phenomenon, then why was the sound heard all over the planet?

Howling of the Earth: Geophysical Theory

Have you read When the Earth Cried Out, written by Arthur Conan Doyle? So, the story speaks of a mystical groan. In the story, Professor Challenger is trying to find out if the planet on which he lives is alive. He begins to drill its surface until the moment when the noise of the Earth occurs. In many things geophysicists agree with the writer, in particular, that our House is alive and knows how to make sounds. In the bowels of the planet, lithospheric plates are displaced and magma moves, which leads either to a creak of the earth or to an earthquake. In the latter case, the planet begins to moan a few minutes before the start of the cataclysm, thereby warning people of the impending threat. However, not in all places where the phenomenon occurred, seismic activity is observed, which casts doubt on this assumption.

Crunch of the Earth: Heliocentric Theory

Professor Elchin Khalilov adheres to this hypothesis. After studying audio materials, he came to the conclusion that the anomalous howl is the result of catastrophes that occur on the Sun. When solar energy collides with the Earth's magnetosphere, acoustic waves are generated that hit our surface. To hear the waves, you need to use special devices, but some people are able to hear them even without instruments, for example, in the case of sound overlapping with low-frequency city noises. By changing the spectrum of urban sounds, the low-frequency wave becomes audible to humans. This sound can be similar to that of a crane, airplane, construction equipment, etc. But why do people start to panic at such sounds? It's all about their frequencies, which negatively affect the human psyche.

Moan of the Earth: Mass Hoax

However, it should be borne in mind that the noise of the Earth can be a large-scale deception, for example, to increase the circulation of newspapers or promote films on a similar topic. Keep in mind that people like to wishful thinking. A large number of versions, each of which has flaws, baffles a person. Even if we want to know the truth about the sounds of the apocalypse, we will face a lack of information. It remains only to wait, maybe in the future someone will shed light on this topic.

Taoist rumble is called a lingering low-frequency sound of unknown origin, which was recorded at different times in distant corners of the planet. It was heard simultaneously by rather large groups of people in northern Europe, Great Britain, Russia and some other parts of the Earth.

This hum is especially often recorded in the United States, in the area of ​​the town of Taos, located in the state of New Mexico. Hence, in fact, the name of the natural phenomenon. The sounds were reported by so many Americans - and there were complaints to the authorities - that in 1997 the US Congress decided to create a group of scientists and send them to the indicated places in order to study the mysterious Taos hum.

Geophysical version: the hum of the Earth

Some eyewitnesses of this strange phenomenon describe it as a very unpleasant, disturbing and even panic-causing low rumble, similar to the operation of many diesel engines somewhere in the distance. Others compare it to the noise of an airplane flying low over the earth's surface. Still others are like the movement of a huge column of heavy equipment along a remote highway.
There have been more or less successful attempts to record this drone on tape. The main question, where is the source of the hum, still does not have an exact answer. There are many versions regarding its origin. One of them is geophysical. The foundation was laid back in 1995, when drilling was carried out in the Kola Superdeep well.

When deeply buried in the rock - up to 12 km - a low-frequency prolonged hum was heard underground. The same one as in Taos. A similar phenomenon is observed in many deep wells. Scientists even deliberately lowered microphones into different boreholes to record this sound. The conclusion suggested itself: a hum is formed when lithospheric plates move deep below the planet's surface.

It intensifies when the time of the earthquake approaches. The colossal energy concentrated in the depths of the planet seems to burst outward, producing a frightening roar. And the louder it is, the greater the likelihood of an imminent cataclysm. On this basis, some scientists even tried to predict earthquakes.

Technogenic version: the work of human hands

The very first evidence of the phenomenon was recorded back in the 70s. This happened in the UK, in the city of Bristol. Residents then began to complain about the low-frequency sound, which lasted for a very long time, periodically repeated and did not give them rest. The local newspaper asked the population to confirm this fact. In response, about 800 people said in the affirmative that they had really heard such a rumble.

First, the authorities approached an industrial plant near Bristol, trying to accuse it of contaminating the "acoustic ecology" of the area. The owners of the business have denied this, arguing that the sound of the business simply cannot be heard that far.

At the same time, quite often the mysterious drone is associated precisely with the work of a person. Geologists argue that during mining and other activities, the "disturbed" planet emits a sort of prolonged groan. In 1982, a group of American scientists came to Akademgorodok in Novosibirsk. Geologist Aleksey Dmitriev, who worked with them, warned them that a series of cataclysms awaited America in the near future.

The scientist explained this by the fact that many high-voltage power lines have been laid along the East Coast of the United States. The frequency of the current in them is 60 Hz. The natural lithospheric currents of the planet have exactly the same. As a result, a kind of "closure" occurs, which can lead to earthquakes. His words were confirmed after 2 years.

Weather version: ice melting

According to another, smaller group of researchers, the noise can be produced by melting ice. When the bonds between hydrogen atoms are broken, a slight crackle occurs. It cannot be caught by any technique, but when there are trillions of such ruptures (or even more), the very same mysterious rumble appears that so worries many inhabitants of the planet.

The previous time he was heard in Great Britain, in Bristol, and for a long time was sorted out in the newspapers. And so he appeared again, this time sweeping across the entire planet. In August 2011, in 2012 and at the beginning of 2013, it was heard in Brazil, USA, Canada, Russia, Ukraine, Australia, Europe and Asia.

Its main feature is that it causes causeless panic in people. He is the so-called "groan" or "hum" of the Earth. Is it a sound hallucination, tectonic plate movement, the sound of acoustic gravity waves, mass psychosis, or just a newspaper duck? Let's try to figure it out.

We hear moans from everywhere

Doug Shafer, Ontario (Canada):
- These sounds were very intense, it seemed that everything was rumbling. It's like a huge ocean.

Natalia and Marina Eroshenko, Rostov-on-Don:
- The noise was so unusual that it cannot even be compared with anything. He was powerful
and scary. Direct roar of some kind, as if an airplane was flying directly over the house.

Tatiana Miteleva, Moscow:
- He came as if from the Earth, but was everywhere. And for me it was a little incomprehensible and scary.

Ilya Bogomolov, Rostov-on-Don:
- He seemed to be everywhere, around. So low, scary enough, unlike any other sound.

Roman and Gennady Ovchinnikov, Novokuznetsk:
- He woke me up at night. A strange hum, even through a closed window. A feeling of unreasonable panic is created. And literally you don't even know what to do at this moment. It really became scary, I thought that it was already necessary to collect things, a child, documents - somewhere to run. It is not clear where he was coming from, the feeling was as if this sound was enveloping.

This is a selection of numerous programs and Internet videos. The largest series of such noises swept across the planet from January 9 to 12, 2012. For these four days, the Earth, according to news correspondents from various channels, literally rumbled. Amateur audio and video recordings have been recorded on all continents. The media assured that no one had ever heard these sounds until now.

This is not entirely true. For years, residents of Taos, New Mexico, in the southwestern United States, have heard a low-frequency hum coming from the desert. The phenomenon is called "Taoist noise". The sound is similar to the movement of heavy equipment on a highway, although there are no major roads in the area of ​​the small settlement.
This sound is heard only by local residents and, extremely rarely, by visitors.

Scientists who have investigated this hum have never been able to find its source. They only suggested that the reason for it might be a large power transmission line passing near the city. Meanwhile, such a noise has been known for a long time, and it is called a sound anomaly.

This is a generic name for a number of phenomena associated with a constant or periodic low-frequency hum that is not distinguishable for all people. These noises are recorded in all parts of the world. In some cases, the sound source has been installed. For example, noise in Hawaii, heard for tens of kilometers, was the result of volcanic activity.

Usually, noises are described by bystanders as an idle sound from a running diesel engine. They, as a rule, cannot be recorded using a microphone, and most importantly, the source cannot be accurately identified.
However, there were cases when the sound was heard not only by a certain part of people. An example of this is the "Bristol Rumble", which was allegedly heard in the UK in the 1970s.

"Sounds of the apocalypse" or "crunch of the earth" - this is the name of the sound anomaly, which was noticed in different parts of the planet in the past two years. Unlike other similar phenomena, the hum was heard by most people, and the equipment recorded it perfectly.

APOCALYPTIC VERSION

Needless to say, even the most incredulous started talking about the notorious end of the world. The fact is that different beliefs say the same thing: a certain sound will notify people about the apocalypse. The Jews believe that it will be, but the trumpet is a shofar, from the sounds of which Jericho once fell. Many immediately began to experiment with audio recordings of the "groan" of the Earth and, of course, came to the conclusion that this was the sound of Jericho trumpets.

Heimdall. The Little Edda Icelandic manuscript, 1760. Heimdall in Scandinavian mythology is the guardian of the gods who lives at the edge of the world, the owner of the golden horn Gjallarhorn, whose sound will be heard in all corners of the world. The sound of his horn will herald the beginning of Ragnarok.

In German-Scandinavian mythology, the golden horn of Gjallarhorn will announce the beginning of the Scandinavian end of the world with a cheerful name Ragnarok. The planet's creak certainly resembles that too. In Kiev, where the Earth also "screamed", they started talking about "Archangel's trumpets", foreshadowing That Day ...

In fact, the "noise of the earth" has been known for a very long time. There are references to a certain "trumpet voice" both in the Bible and in the Koran. The ancient Greeks explained the underground groans by the fact that in its depths there were one hundred-armed giants, cast down by the gods into the bosom of the Earth. According to mythology, it was not only they who were tormented - Mother Earth also "groaned" from them.

MANUAL VERSION

The most common. Some geologists, for example, associate the mysterious rumble in Novokuznetsk with the development of coal in the Kuzbass. The energy of rock explosions allegedly accumulates in the Earth, and provokes either man-made earthquakes or mysterious noises.

Scientists from the Novosibirsk Academgorodok share a similar version. In 1982, when the Americans arrived in the town, one of the geological professors, Aleksey Dmitriev, allegedly warned them that serious cataclysms would soon await America, meaning man-made earthquakes and noises. The Americans did not believe him then, but in 1984 geophysical hums and small earthquakes swept across the entire East Coast of the United States.

Alexei Dmitriev argues that it was not difficult to predict them, since more than a dozen energy-intensive high-voltage power lines stretch along the East Atlantic coast of the United States. The frequency of the transmitted current in the US power system is 60 Hz. And since it corresponds to the frequency of natural lithospheric currents, a "short circuit" occurred ...

The technogenic version has only two drawbacks. If the cause of the noise was a "production" factor, then how to explain that the sound was heard in different parts of the planet almost simultaneously? The second drawback - if you believe, again, all the same eyewitnesses, then power lines, thermal power plants, factories, construction sites and other technical facilities were not always close to the place where the "groan" was heard.

VERSION GEOPHYSICAL

Arthur Conan Doyle has a story called When the Earth Screamed. The hero of the story, Professor Challenger, decides to find out if the Earth is "alive". To do this, he drills a giant hole in it. And when the drill penetrated very deeply into the earth's strata, the planet ... screamed.

In this story, only the ending is fantastic. In other respects, geophysicists are in solidarity with the writer - the Earth is really "alive", and it really "screams".

In the bowels of our planet, convection, the movement of magma flows and the displacement of lithospheric plates constantly take place. This leads to the fact that the Earth is noisy. And scientists learned how to record her "voices" long ago. To do this, they come to boreholes drilled for technical or scientific purposes, and put ultrasensitive microphones into them. The ordinary human ear is unable to hear this sound in most cases.

But there are also exceptions. They can occur, for example, during an earthquake, just before tremors. However, this is not surprising: during earthquakes, lithospheric plates move, so the process, of course, can be accompanied by strong noise.

It is noticed that before a large earthquake, the level of the earth's roar rises sharply. The earth seems to warn of an impending earthquake and gives people the opportunity to estimate its strength in advance and localize the epicenter.

In fact, in the depths of the Earth, earthquakes never stop. But it is practically impossible to predict which of them will "burst" to the surface in advance. Aleksey Lyubushin, chief researcher at the Schmidt Institute of Physics of the Earth, Russian Academy of Sciences, once succeeded. A major earthquake in Tohoku (Japan), which occurred in 2011 and killed at least 16,000 people, he predicted in as many as three years.

The fact that earthly noise under Japan began to synchronize (according to the scientist's hypothesis, this is the first sign of an impending powerful earthquake), Lyubushin noticed back in 2008 and published several warnings on this topic.

The Japanese did not believe it. The most unpleasant thing is that after the catastrophe, the synchronization of the low-frequency noise was preserved. Alexey Lyubushin believes that Japan will face another earthquake, no less devastating, and its epicenter should be located near the capital of the country - Tokyo. That is why the noise of the Earth can and should be studied. With their help, the planet not only informs about earthquakes, but also helps, for example, to search for oil and other minerals.

But, alas, not all "screams" of the Earth can be explained by impending earthquakes. After all, where they were supposedly heard in the last two years, no seismic events have ever happened! could not - often these were areas where they do not exist in principle.

WEATHER VERSION

Some scientists speculate that the planet's creak is related to the weather: fog, dampness and rain. When ice melts, part of the hydrogen bonds between water molecules breaks. Each gap releases energy and can generate a faint audible click. Therefore, according to the hypothesis of these scientists, if the noise is heard during fog or when there are clouds in the sky, this is the “song of water”, which can be accompanied by a hum. Of course, a single snowflake creates only minor noise, but when large amounts of ice melt, everyone can hear the sound.
Unfortunately, the version does not answer the question of why noises are heard in summer, in clear weather.

VERSION HELIOCENTRIC AND OTHER

It is adhered to by Professor, Doctor of Geological and Mineralogical Sciences, Chairman of the Board of the International Committee on Global Geological and Environmental Changes, President of the Global Earthquake Forecasting Network (GNFE) Elchin Khalilov. He studied audio recordings of earth noise from different parts of the planet, and found that they are all remarkably similar. From this, he concluded that the noise is a consequence of cataclysms on the Sun.

When streams of solar energy, after the next release, rush to the Earth and crash into the magnetosphere, this leads to the emergence of special acoustic waves, which then rush to the surface of the Earth. These waves can only be heard with special instruments. However, some people are also able to hear them if the sound is superimposed on the low-frequency city noise. A low-frequency wave changes the spectrum of city noise, and then a person can hear such an ominous "groan".

On the audio recordings, one can hear that the hum is, indeed, similar to the usual city noise - of a crane, an aircraft, construction equipment - but amplified many times over. The fact that this sound often causes a feeling of panic among eyewitnesses, Elchin Khalilov explains by its low frequency. It is known that low frequencies, although not distinguished by the ear, have a bad effect on the human psyche. An example of this is the famous research of the French professor Gavreau, who established precisely at what frequencies of infrasound a person begins to rupture the eardrum, hemorrhage into the brain, and at which even death.

The negative influence of infrasound on the psyche was recently demonstrated by Dr. Richard Lord and Professor of Psychology Richard Wiseman by organizing an unusual concert of organ music in Liverpool Cathedral. In two of the four compositions, the sounds of a 7-meter organ, specially designed for the experiment, were added. The peculiarity of the giant instrument is that the sounds it makes have a frequency below 20 kHz, so the human ear is simply unable to hear them.

Thus, the volunteers who listened to the concert did not even know exactly when the organ began to play. Scientists managed to establish that among the negative sensations that appeared in people during organ play were fear, loss of strength and mood, sadness. Many had goosebumps running down their skin.

In the 1960s of the last century, against the background of a general upsurge in the economy, science and culture in our country, Soviet scientists conceived an ambitious project - drilling a well of an unprecedented depth of 15 km. This project was supposed to mark another "psychological" victory over the United States. The victory of science was in learning more about the structure of the Earth.

The Americans also thought about the possibility of drilling such a super-deep well, but after weighing all the pros and cons, they decided that it would be easier to fly to the moon. But the Russians, as usual, did not give up.

And on the Kola Peninsula, a well appeared with a depth of just over 12 km. The Soviet scientists did not reach the declared level, but they broke the world record and got into the Guinness Book of Records. These tests literally and figuratively "undermined" all theories about the structure of the Earth that existed until then. It turned out, for example, that there is water even in the deepest layers of our planet, and the temperature at great depths was not at all as high as previously thought. There are many tales about the Kola well. One of them says that once geophysicists lowered a microphone there and clearly heard human screams, confirming that hell really exists.

It has long been known that infrasound inherently accompanies many natural phenomena: hurricanes, tsunamis, gusts of wind, noise of waves, volcanic eruptions, thunderstorms, sudden pressure drops, etc. and with infrasound, which is formed in the atmosphere.

According to one of the versions, the mysterious rumble is associated with the change of magnetic poles, which is now taking place on our planet. And psychologist from the University of Chicago, Neil Johnson, believes that the noise of the Earth is associated with the psychological characteristics of those people who hear it.

Researchers at Earthscope USArray have discovered a series of infrasonic noises generated by the collision of two ocean waves. The resulting sound from such collisions, in principle, can spread over the entire globe, so that the cause of the hum may not be the earth, but water.

There is also a version that the "sounds of the apocalypse" is just a massive hoax, a large-scale newspaper duck using fake videos to promote films such as "Red State" or "Alien Invasion: Battle of Los Angeles 2". The premieres of these films took place in 2011, almost immediately after the earthlings heard the “cry of the planet”. However, the human ability to pass off wishful thinking is also known, and the trait of many media outlets is the wishful thinking to be passed off as a sensation.

Such a number of hypotheses baffles a person who wants to find the only correct explanation for the sound of the planet. At least for now. Perhaps the groan of the Earth is indeed a multifactorial phenomenon, one way or another associated with each of these versions.

NAKED SCIENCE January, 2014

If you move away from the multifaceted cacophony of big cities with their noisy soundtrack, you can hear more harmonious and soothing melodies. This is the sound of the wind and the rustle of grasses, waves of seas and oceans beating against the coast and the creak of trees, the sound of drops and the sound of rain, loved by many.

Hum of the earth

However, in addition to the sounds of nature we are used to, there is another sound, it is constantly present on our planet. And only recently it became known that this is the hum of the Earth itself.

The reasons why our planet is "buzzing" lie in its depths. This hum is created by vibrations of the subtlest seismic movements that occur in the Earth itself. They are so insignificant that they cannot be detected without special equipment.

Research in this area

You may not hear how our planet "buzzes", but this process is happening all the time. Now scientists have managed to measure this noise at the bottom of the ocean.

Most earth vibrations are so subtle that people don't notice them. We feel only real earthquakes, although in fact there are many more of them, up to 500,000 every year, if you take into account the smallest of them, which are left unattended by people. Of this amount, only a fifth can be felt in some way, and only a hundred of them can do damage due to their power.

Back in the 90s, scientists learned about the "free vibrations" that can be detected on land using seismometers.

For many years, the source of this hum was incomprehensible. Researchers believed that these sounds came from the bottom of the oceans, while others attributed the noise to the collision of ocean waves. Only three years ago it was determined that these causes also play a role in maintaining the vibration of the Earth.

Exploring the oceans

Traveling to the bottom of the Indian Ocean, scientists used ocean seismometers to capture humming sounds. On an area of ​​more than 2000 km 2, 57 research devices were installed. Here, near Madagascar, they spent over a year.

With the help of special filters, seismometers screened out the noises common to the ocean, created by the movements of waves and the usual life in the water. Thus, it was possible to catch a special hum in the same amplitude ranges as the sound received earlier on land in Algeria. A person cannot hear something like this in any way, because the hum is within 20 hertz, which is 10,000 times lower than the human hearing threshold.

The study of the oceans has provided much more data explaining the previously incomprehensible noise. Until that moment, research carried out on land had never given such a result.
