Taos rumble: the terrible secret of the Earth. Studying the phenomenon of "Earth Moan" from a scientific point of view Sound throughout the earth

Beginning around 2005, people around the world began to hear sounds that were later called Hum, Groans or Earth Creaks. Similar sounds have been heard before in some parts of the planet, but this phenomenon made itself felt especially often in the period 2011-2012.

There are various versions of the origin of these sounds: from apocalyptic to heliocentric. You can get acquainted with them, for example, in the article "Studying the phenomenon of "Moan of the Earth" from a scientific point of view"

I propose to look at the Earth's Hum from the other side. What people hear really belongs to the planet itself. The hum of the Earth is the so-called Schumann frequency, which suddenly acquired a voice that people can hear.

Our planet is a living organism that has its own oscillation frequency (vibrations/pulsations). This frequency is measured in hertz (1 Hz is 1 oscillation per second. 1 kHz is 1000 oscillations per second) and is called the Schumann frequency or resonance. The Schumann frequency is not constant and not uniform. It changes throughout the day and seasons. Its indicators will differ in different parts of the planet, depending on the energy flows established there.

We are interested in the question: “If the Schumann frequency has always been inherent in the Earth, then why has it only now become available to hearing? a large number of people?"

Since 1986, scientists have been observing an increase in the frequency vibrations of our planet, which rose from 7 Hz to 14-15 Hz. From time to time, energy bursts occur on Earth with a frequency about 16 Hz, and this is the oscillation frequency that the average person ALREADY perceives and considers sound! For their part, the people themselves have changed. As a result of the transformation of the senses, including hearing, we begin to hear what was previously outside the zone of our perception. I.e some people begin to hear air vibrations with a frequency below 16 Hz. When such “hearing” people fall into the Schumann frequency burst zone, they become a witness to the Earth’s hum, which they then tell their “deaf” neighbors, police and rescue services.

In fact, everything that we are accustomed to consider as sound is a kind of vibrations of a solid, liquid or gaseous medium, which is transmitted through the air to a person in the form of a sound wave in the range of 16 Hz - 22 kHz. It is these frequencies that are perceived by the hearing organs and the brain of an average person.

To make it clear, let me give you an example. Let's take an ordinary wooden ruler and press it 1/3 to the table, and bend the free end down a little and let go. The ruler will begin to oscillate, and we will hear a sound (t-dr-r-r). This happens because a solid body (ruler) oscillates and vibrates the air around it. A wave in the form of spheres propagates through the air in all directions. Since the air is invisible, we cannot see these spheres, but we can hear them.

Thus, increasing the frequency of oscillations of the planet and near-Earth space, up to about 15-16 Hz, made them audible for some sensitive people. This explains why the Earth Rumble is not heard by the entire population of the city where this phenomenon was observed.

The second reason for the selective audibility of the Earth's hum is that the Schumann frequency can vary greatly in different parts of the planet. Where the level of fluctuations is much lower than 16 Hz, people do not hear the hum of the Earth. But in places where the level of fluctuations jumps to 15-16 Hz and above, people hear them.

Sharp fluctuations in oscillations from 8 to 16 Hz and above occur in places where high-frequency energy flows coming from space are present. These New "light" energies are pushing out the "heavy" low frequency energies of the 3rd Dimension. A similar replacement occurs every night, so people often hear the Earth Rumble at night.

During the day, high-frequency energy flows, as lighter ones, rise again. They are picked up by the winds and carried all over the planet. Sometimes these streams are pressed quite low to the ground even during the day, so people hear the Earth's hum even in the daytime. Most often, this happens in nature, over the oceans and seas, where the Earth's hum is more like the music of the spheres or the sound of the ocean. These flows linger in those places because there are no huge concentrations of people with a level of consciousness of the 3rd Dimension, whose energies repel high-frequency energy alien to them.

It has been noticed that the Earth hum is often heard before or during natural disasters. This is natural, because through cataclysms the planet is cleared of obsolete low-frequency energies. In places of such cleanings, there is a sharp increase in the frequency of vibrations of space up to 15-16 Hz and higher. As a result, people begin to hear "groans, creaks, thunders," and so on.

This sound often causes a state of fear in eyewitnesses. It is believed that low frequencies (infrasound), although they are not distinguished by the ear, have a bad effect on the human psyche. In fact, people are panicked by sounds with a frequency of 7 Hz, and they have nothing to do with the hum of the Earth.

The perception of the Hum of the Earth depends entirely on the person himself. Fear arises in people who do not like change in life. The new and the unknown means for them the loss of the familiar old. The rumble of the Earth is a Sign and a Call for change. People who are ready for change will hear not a groan and a rattle, but the music of the spheres, the sound of the sea or the ringing of bells. Such sounds can surprise, please, but not scare.

If someone was lucky enough to witness the Earth's Hum, then I advise you to listen to your feelings at this moment. Fear will indicate your attachment to the old world of duality. Joy will show your willingness to change yourself, and through it the rest of the world. After all, it has long been known: if you want to change the world, start with yourself.

I wish you all peace in your soul, joy, love and courage during your meeting with the New.

In preparing the article, materials from the links below were used.

The last time he was heard in the UK, in Bristol, and was sorted out in the newspapers for a long time. And now he reappeared, swept this time around the planet.

In August 2011, in 2012 and early 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. What is it - a sound hallucination, the movement of tectonic plates, the sound of acoustic-gravity waves, a mass psychosis, or just a newspaper duck? Let's try to figure it out.

From everywhere we hear groans

Doug Schafer, Ontario (Canada):
- These sounds were very intense, everything seemed to rumble. It's like a huge ocean.

Natalia and Marina Eroshenko, Rostov-on-Don:
- The noise was so unusual that it can not even be compared with anything. He was powerful
and terrible. Just some kind of roar, as if a plane were flying right over the house.

Tatyana Miteleva, Moscow:
- He walked 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, quite frightening, unlike all other sounds.

Roman and Gennady Ovchinnikov, Novokuznetsk:
- He woke me up at night. A strange rumble, penetrating even through a closed window. There is a feeling of panic for no reason. And literally do not 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 - to run somewhere. It is not clear where he was coming from, the feeling was as if this sound was enveloping.

This is a cut from 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 made on every continent. The media assured: until now, no one had ever heard these sounds.

This is not entirely true. For many years, residents of the town of Taos in the state of New Mexico in the southwestern United States have heard a low-frequency rumble coming from the desert. The phenomenon is called "Taos noise". The sound is similar to the movement of heavy equipment on the 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 studied this hum have not been able to find its source. They only suggested that a large power line passing near the city could be the reason for it. Meanwhile, such noise has been known for a long time, and it is called a sound anomaly.

This is a generalized name for a number of phenomena associated with a constant or periodic low-frequency hum that is not distinguishable by all people. These noises are fixed in all points of the globe.

In some cases, the sound source has been established. For example, the noise in Hawaii, heard for tens of kilometers, was the result of volcanic activity.

Usually, the noises are described by witnesses as an idle sound from a running diesel engine. They, as a rule, cannot be recorded with a microphone, and most importantly, the source cannot be accurately determined.

However, there were cases when the sound was heard not only by some certain part of the people. An example of this is the "Bristol hum", which was allegedly heard in the UK in the 1970s.

"Sounds of the Apocalypse" or "the creak of the Earth" - this is the name of the sound anomaly, which was noticed in different parts of the world in the past two years. Unlike other similar phenomena, the hum was audible to most people, and it was perfectly recorded by the equipment.

APOCALYPTIC VERSION

Needless to say, even the most incredulous people started talking about the notorious end of the world. The fact is that different beliefs say the same thing: a certain sound will inform people about the apocalypse. The Jews believe that it will be, but the trumpet of the 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 the Jericho trumpets.

Heimdall. Icelandic manuscript "Edda Minor", 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, the sound of which 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 Gjallarhorn will announce the beginning of the Scandinavian end of the world with the cheerful name Ragnarök. The creak of the planet certainly reminds him. In Kyiv, where the Earth also “screamed”, they started talking about the “Arkhangelsk trumpets”, foreshadowing That Same 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 hundred-armed giants, cast down by the gods into the bosom of the Earth, were imprisoned in its depths. According to mythology, they were not the only ones suffering - Mother Earth also “groaned” from them.

MAN-MADE 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.

A similar version is shared by scientists from the Novosibirsk Akademgorodok. In 1982, when the Americans arrived in the town, one of the geology professors Alexei Dmitriev allegedly warned them that serious cataclysms would soon await America, meaning man-made earthquakes and noise.

The Americans did not believe him then, but in 1984, geophysical hums and small earthquakes swept along the entire East Coast of the United States.

Aleksey Dmitriev argues that it was not difficult to predict them, since more than a dozen energy-intensive high-voltage transmission lines are stretched along the East Atlantic coast of the United States.

The frequency of the transmitted current in the US power supply system is 60 Hz. And since it corresponds to the frequency of natural lithospheric currents, a "short circuit" has occurred...

The man-made 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 far from always located close to the place where the "groan" was heard.

VERSION GEOPHYSICAL

Arthur Conan Doyle has a story called When the Earth Shouted. 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 layers, the planet ... screamed.

In this story, only the ending is fantastic. Otherwise, geophysicists are in solidarity with the writer - the Earth is indeed “alive”, and it really “screams”.

In the bowels of our planet, convection is constantly taking place, the movement of magma flows and the displacement of lithospheric plates. This is what causes the Earth to be noisy. And scientists have learned to record her "voices" for a long time. To do this, they come to wells drilled for technical or scientific purposes and drop ultra-sensitive microphones into them. The normal human ear is unable to hear this sound in most cases.

But there are exceptions. They can occur, for example, during an earthquake, immediately 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 major earthquake, the level of the earth's rumble rises sharply. The Earth seems to warn of an upcoming earthquake and gives people the opportunity to assess its strength in advance and localize the epicenter.

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

The fact that ground noises 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. The most unpleasant thing is that even after the disaster, the synchronization of low-frequency noise was preserved. Alexey Lyubushin believes that another earthquake awaits Japan, no less devastating, moreover, its epicenter should be located not far from 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 reports earthquakes, but also helps, for example, to search for oil and other minerals.

But, alas, not all the “cries” of the Earth can be explained by impending earthquakes. After all, where they were allegedly heard in the last two years, there were no seismic events and there will be! could not - often these were areas where they do not exist in principle.

WEATHER VERSION

Some scientists suggest that the creaking of the planet is related to the weather: fog, dampness and rain. When ice melts, some of the hydrogen bonds between water molecules break. Each such break releases energy and can generate a slight sonic 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 “water song”, which can be accompanied by a rumble. Of course, one snowflake creates only a small amount of noise, but when large amounts of ice melt, everyone hears the sound.

Unfortunately, the version does not answer the question why noises are heard in summer, in clear weather.

VERSION HELIOCENTRIC AND OTHERS

It is followed by a professor, doctor of geological and mineralogical sciences, chairman of the board of the International Committee for global change geological and environment, President of the Global Network for Earthquake Prediction (GNFE) Elchin Khalilov.

He studied audio recordings of terrestrial noise made in different parts of the planet, and found that they were all remarkably similar. From this, he concluded that the noise is a consequence of cataclysms on the Sun.

When the flows solar energy after the next ejection, they rush towards the Earth and crash into the magnetosphere, this leads to the emergence of special acoustic waves, which then rush to the Earth's surface. These waves can only be heard with the help of special instruments.

However, some people are also able to hear them if the sound is superimposed on low-frequency urban noise. A low-frequency wave changes the spectrum of urban noise, and then a person can hear a similar ominous "groan".

On the audio recordings, you can hear that the rumble is really similar to the usual city noise - a crane, an airplane, construction equipment- but amplified. 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 Gavro, who precisely established, under the influence of which frequencies of infrasound in a person, a rupture of the eardrums, a brain hemorrhage, and under which even death begins.

The negative impact of infrasound on the psyche was recently demonstrated by Dr. Richard Lord and professor of psychology Richard Wiseman, who organized an unusual concert of organ music in the Liverpool Cathedral. The sounds of a 7-meter organ specially designed for the experiment were added to two of the four compositions. 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 when exactly the organ began to play. Scientists managed to establish that among the negative sensations that appeared in people during the organ playing were fear, loss of strength and mood, sadness. Many had goosebumps.

In the 1960s of the last century, against the backdrop of a general rise in the economy, science and culture in our country, Soviet scientists conceived a grandiose project - drilling a well with an unprecedented depth of -15 km. This project was supposed to mark another "psychological" victory over the United States. The victory of science was to learn more about the structure of the Earth. The Americans also thought about the possibility of drilling such an ultra-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 now a well with a depth of just over 12 km appeared on the Kola Peninsula. 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 turned out to be 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, wave noise, volcanic eruptions, thunderstorms, sudden pressure drops, etc. Feeling unwell during vibrations atmospheric pressure associated, among other things, with infrasound, which is formed in the atmosphere.

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

Researchers at Earthscope USArray have detected a series of infrasonic noises produced when two ocean waves collide. The resulting sound from such collisions can, in principle, propagate throughout the globe, so 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 mass hoax, a large-scale newspaper duck using fake videos to promote films like "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 a feature of many media outlets is wishful thinking.

Such a number of hypotheses confuses 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 connected with each of these versions.

Magazine "NAKED SCIENCE" January, 2014

20.09.11 This strange sound from different parts of the Earth is reported more and more often, sometimes the sound precedes an earthquake. These sounds are heard not only by individuals, but also by entire stadiums, and sometimes even entire cities.

The day before a major earthquake in the Northeastern United States, a strange sound was heard during a baseball game, which was recorded on video (see below). The sound was also reported from Russia, Canada and elsewhere, and also preceded the earthquake.

"Woodpecker Phenomenon"

We know that in the 70s the Russians' electromagnetic pulse technology caused a woodpecker effect that was transmitted to the US.

And people were already concerned about the effects on the brain.

One can only imagine what the ionospheric heater and other technologies are capable of now.

All this is very strange, and thanks to youtube all these phenomena are well documented.

(Below) In the US, this phenomenon has only recently occurred... Of course, the explanation given was that it was a PA system. It's the same sound as in the video above... where there were no stadiums or PA systems... And just before the earthquake in the Northeast!

(Below) Here's another example. This strange sound is similar to the sound during a baseball game, and in some other clips.

Next example. This time is a little different. The high-pitched sound was preceded by a day with strange clouds and a rainbow - and 11 hours later, a magnitude 5 earthquake also hit the region.

Note. mixednews: We've added a few more videos with strange sounds. All of them took place in different countries and cities: in Russia, Ukraine, Poland, USA, Canada, Brazil…

Judging by the tone, they all presumably have the same nature. In addition, there is another common point: almost all of these sounds took place in August 2011 (see video dates).

Tula, Russia:

Krasnoyarsk, Russia:

Moscow, Russia:

Kyiv, Ukraine:

Odessa, Ukraine:

Zhitomir, Ukraine:

Lodz, Poland:

Curitiba, Brazil:

South East England

In this case, the sound is different from others. The author of the video writes: The sound was recorded on August 24, 2011 in South East England. The place where I live is very isolated and there are only 12 other private houses near me. The nearest town is more than 20 kilometers away. Most of all, it looks like the sound of a huge steam locomotive ... However, it was difficult to determine where the sound was coming from. It seemed to come from everywhere. And the nearest railway station is over 60 kilometers away. Other neighbors were awakened by this strange sound, but also could not explain what it was. Then the sound suddenly stopped. AT total it lasted about 15 minutes.

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, the waves of the seas and oceans beating against the shore and the creaking of trees, the sound of drops and the sound of rain loved by many.

The hum of the earth

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

The reasons why our planet "hums" lie in its depths. This rumble is created by the 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 "hums", but this process happens all the time. Now scientists have been able to measure this noise at the bottom of the ocean.

Most Earth wobbles are so small that people don't notice them. We feel only real earthquakes, although in fact there are many more, up to 500,000 every year, if you count the smallest ones that go unnoticed by people. Of this number, only a fifth can be felt in any way, and only a hundred pieces can deal damage due to their power.

Back in the 90s, scientists became aware of "free oscillations" that can be detected on land using seismometers.

For many years the source of this hum was incomprehensible. Researchers believed that these sounds come from the bottom of the oceans, 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 keeping the Earth vibrating.

Exploring the oceans

After going to the bottom of the Indian Ocean, the scientists used ocean seismometers to capture the buzzing sounds. Over an area of ​​more than 2000 km2, 57 research apparatuses were installed. Here, near Madagascar, they spent more than a year.

With the help of special filters, seismometers filtered out the noises common to the ocean, created by wave movements and habitual life in the water. Thus, it was possible to catch a special rumble in the same amplitude ranges as the sound previously received on land in Algeria. There is no way a person can hear something like this, because the hum is within 20 hertz, which is 10,000 times lower than the human hearing threshold.

The study of the oceans has yielded much more data to explain the previously incomprehensible noise. Up to this point, studies conducted on land did not give such a result.

The Taos rumble is a low-pitched low-frequency sound of unknown origin, which was recorded at different times in remote corners of the planet. It was heard at the same time by quite large groups of people in the north of Europe, in Great Britain, in Russia and some other points on the Earth.

Especially often this rumble is recorded in the USA, 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 designated places to study the mysterious Taos rumble.

Geophysical version: Earth rumble

Some witnesses of this strange phenomenon describe it as a very unpleasant, disturbing and even panic low rumble, similar to the work 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 - 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 hum 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.

With a strong penetration into the rock - up to 12 km - a low-frequency lingering rumble was heard underground. The same as in Taos. A similar phenomenon is observed in many deep wells. Scientists even deliberately lowered microphones into different wells to record this sound. The conclusion suggested itself: the rumble is formed when the lithospheric plates move deep under the surface of the planet.

It intensifies when the time of the earthquake approaches. The colossal energy concentrated in the depths of the planet, as it were, breaks out, producing a frightening roar. And the louder it is, the greater the likelihood of an imminent cataclysm. According to this sign, 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. It happened in the UK, in the city of Bristol. Residents then began to complain about the low-frequency sound, which lasted a very long time, was periodically repeated and did not give them rest. The local newspaper appealed to the population with a request to confirm this fact. In response, about 800 people stated in the affirmative that they really heard such a rumble.

First, the authorities turned to located near Bristol industrial enterprise, trying to blame him for polluting the "acoustic ecology" of the area. The owners of the facility denied this, arguing that the sound of the facility simply could not be heard that far.

At the same time, quite often a mysterious hum is associated precisely with the work of a person. Geologists say that during mining and other activities, the “disturbed” planet emits a sort of long-drawn-out groan. In 1982, a group of American scientists came to Akademgorodok in Novosibirsk. Geologist Aleksey Dmitriev, who collaborated 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 were laid along the East Coast of the United States. The current frequency in them is 60 Hz. The natural lithospheric currents of the planet have exactly the same. As a result, a kind of "short circuit" occurs, which can lead to earthquakes. His words were confirmed after 2 years.

Weather version: melting ice

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 crack occurs. It cannot be caught by any technique, but when there are trillions (or even more) of such gaps, that very mysterious rumble appears, which worries so many inhabitants of the planet.
