Cielomoto, an earthquake in the air

Earthquakes already surprise everyone in the area, but those that occur in the air are even more surprising. And it is that, imagine that you are walking calmly, and you begin to notice something strange. In that, you look up at the sky and see something strange, which causes loud rumbles and it can even cause tremors. How would you feel?

The phenomenon is known by the name of sky motorcycle, Skyquake or Skyquake. While not new, scientists have so far been unable to provide a logical explanation of how and why it forms.

The skies can be formed anywhere in the world, but in the United States, South America and Australia they have been the last to see it. Citizens who were sleeping peacefully, and who suddenly began to hear a sound that made the window panes vibrate. Anyone could think that it was the beginning of an Armageddon or the end of the world. And in fact, it is common for people who have seen it to write alarmist comments on their social media profiles. But the reality is that there is nothing to worry about.

What Causes Skies?


As we said, there is still no single theory that explains the phenomenon. Now, if you live or have been living in a coastal region for a while, you have probably heard the waves crash against the cliffs. Well, it turns out that the powerful noise it generates may be due to methane released by crystals from the ocean floor. With combustion, this is a gas that could produce a great roar.

Following the waves, surfers often say that they have heard very loud sounds while practicing this sport. Even tsunamis can be accompanied by this amazing sound.

Other theories indicate that skylights could be produced by:

  • supersonic aircraft that break the sound barrier
  • un meteorite that has exploded in the atmosphere
  • earthquakes


However, all these theories could not be demonstrated. It is true that sky-moths do occur in coastal regions, but they don't just form there; On the other hand, experts in supersonic planes deny that the sound of the skies is similar to that of the aforementioned vehicles. And, in the case of meteorites, these rocks from outer space when they enter the atmosphere leave a flash of light, which will be brighter the larger it is. Skies do not give off any kind of light.

Thus, the most accepted scientific explanation is the one that says that when layers of hot and cold air collide with each other they create an explosion, thus causing a sound that, surely, you cannot easily forget. So much so, that it is common for people to need medical attention due to severe headaches, an upset stomach or other minor problems.

 It's new?

It is very rare, but no, it is not a new phenomenon. It must be proven that they have existed since the month of February 1829. At that time, a group of settlers in New South Wales (in Australia) wrote in their travel log: 'At about 3 in the afternoon, Mr. Hume and I were writing a letter on the ground. The day had been surprisingly good, without a cloud in the sky or the slightest breeze. Suddenly we heard what appeared to be the detonation of a cannon at a distance of five to six miles. It was not the hollow sound of a terrestrial explosion, nor the sound produced by a falling tree, but the classic sound of an artillery piece. (…) One of the men immediately climbed a tree, but could not see anything out of the ordinary.

On any continent it has ever been seen. In Ireland, for example, they are very frequent, so we are talking about a phenomenon that really exists, but about which we still do not know much. In the 70s, skylines became such a cumbersome issue for the United States that President Jimmy Carter ordered a official investigation on the matter. Unfortunately, he could not find out the origin of the skies.

Famous cases of cielomotos

Storm clouds

In addition to those mentioned, there are other famous cases:

  • Very few years ago, in 2010, a sky motorcycle was reported in Uruguay. Specifically, it was on February 15 at 5 in the morning (GMT time). It caused, in addition to the noise, tremors in the city.
  • On 20 October 2006, towns between Cornwall and Devon, UK, said that "mysterious explosions" had damaged houses.
  • On January 12, 2004, one of these phenomena shook Dover (Delaware).
  • On February 9, 1994, one was felt in Pittsburgh (United States).

Since they cannot be detected at the moment, we will have to have patience and wait to see when and where the next one will occur. Who knows, maybe it happens closer than you think.

    Last night, that is .. March 23, 2016, at 23.30:2010 p.m. Uruguay time, in the city of Montevideo, more precisely in a neighborhood called Santa Catalina, bordering the Montevideo hill, a sky-motorcycle occurred. I understand that it already happened, in 2011, XNUMX and now on this occasion. The neighbors heard the tremendous sound, and felt their houses shake, they thought of a nearby regasification plant ... but it is not operational.

    This event occurred today, Thursday, February 27, 2020 at 02, in the city of Bahía de Caráquez, in Ecuador.
    A powerful sound was heard in the sky, as if an explosion had occurred, and although no movements were perceived on the ground (which gave us calm in the face of an earthquake), the windows and doors were shaking.
