In houses on Ostrovityanova Street in the south-west of Moscow, glass was broken and walls were partially destroyed after an incident in one of the houses. On the morning of November 10, a fire broke out on the first floor in building 23/1. Residents of the house claim that the fire was preceded by an explosion.
Windows were also broken in houses in the neighborhood - 300-400 meters from the epicenter of the explosion. This is what house 27/3 on the same street looks like.

Residents of the house were placed in a nearby kindergarten. In addition, Mosgortrans allocated two buses for them. “Two extra-large capacity LiAZ-6213 buses were sent to the address: st. Ostrovityanova, 23/1 to accommodate people forced out into the street due to the fire,” the company said.
These are the buses:

“We had a very loud [clap]. Around 06:30 - I didn’t even look at my watch - there was a very strong roar and explosion. It just shook, I thought the house was collapsing. I jumped up, looked out the window - glass was lying around, the alarms of all the cars went off,” the interlocutor said.
The gas explosion was also reported in the media in the morning. Local residents interviewed by the Zvezda TV channel said that they did not smell gas. “The thing is that there was no smell. After the explosion, we all jumped up and began questioning everyone. Surprisingly, no one smelled the gas. Usually it smells strongly, especially if there has been an accumulation of it,” the interlocutor emphasized.
Meanwhile and. O. General Director of Mosgaz Pavel Chichikov. According to him, experts carried out an inspection and found no traces of a gas leak or subsequent explosion. Now the gas in the house is shut off.
A reader asked us this question Masha Nugmanova.
Dear Masha! If you detonate a nuclear bomb, it won't be good. Nowhere and no one. Therefore, detonating nuclear bombs without parents is strongly discouraged.
Now look. The depth at the Challenger Deep, the deepest point of the Mariana Trench, is 11 kilometers.
The power of the most powerful thermonuclear (hydrogen) bomb ever tested by people is 50 million tons of TNT (50 megatons). This is three and a half thousand times more powerful than the bomb dropped by the Americans on Hiroshima in 1945.
What won't happen
There is a video on YouTube in which some guy claims that a tsunami wave after such an explosion will wash away all of Japan, half of America and half of Australia. This is, to put it mildly, nonsense.
For example, two and a half million years ago, the so-called Eltanin asteroid fell into the ocean between South America and Antarctica. As a result of the explosion, a tsunami wave of a kilometer (estimated) height was actually raised, which greatly battered a piece of Antarctica and the southern part of the South American continent. Although in general no catastrophic consequences were observed for the Earth.
So, the energy of the explosion of the Eltanin asteroid is 5,000,000 megatons (that is, 5 TERATONS), it is 100,000 times greater than the energy of the explosion of the Tsar Bomba. The moral of this story is this: no matter how deadly and destructive the effects of man-made weapons may seem to us, the scale of natural disasters is simply incomparable.
What will happen
When exploded in the air, such a bomb forms a fireball or “bubble” with a diameter of four and a half kilometers. However, water is not air. Water, unlike air, is very difficult to compress; Don’t forget about the monstrous pressure at an eleven-kilometer depth.
Calculations show that the diameter of the primary “bubble” will be about 1 kilometer. However, as soon as the pressure of the hot gas weakens, the surrounding water “collapses,” again compressing the “bubble.” As a result, we will get a series of several shock waves, increasingly weaker. Finally, a stream of very hot and radioactive water will rise to the surface of the ocean. However, on the surface we will not see any explosion, no water column, or tsunami wave.
The main danger of such an explosion (apart from radiation) lies elsewhere. The Mariana Trench is one of the most unstable geological places on Earth; at this point the Pacific Plate is subducting under the Philippine Plate. A powerful explosion at the bottom can trigger earthquakes and underwater landslides within a radius of several hundred or even thousands of kilometers. In this case, a tsunami wave (or even a whole series of such waves) can no longer be avoided.
The explosion of a thermonuclear bomb itself can generate a tsunami wave only if it occurs at shallow depths near the coast. In this case, the water pressure will be low, and the “bubble” will reach a diameter of 4 kilometers. A very large (about 30 cubic kilometers) “funnel” is formed, into which ocean waves will rush; the energy of the collision will generate a tsunami wave - however, by natural standards, a very small one. A city or village on the coast near the explosion site will, of course, be destroyed - but this will most likely be the end of the matter. The energy of such a wave is simply not enough to cause significant damage over a long distance.
Natural tsunamis that cause severe destruction at large distances from the epicenter initially have significantly greater energy. For example, the giant European tsunami of 6100 BC arose as a result of an underwater landslide with a total volume of 3,500 cubic kilometers, which is 115 times more than the volume of the “bubble” during the underwater explosion of the Tsar Bomba.

Back in the late 1950s, the US Air Force was working to detonate a nuclear device on the Moon. In 2000, former NASA head Loenardo Reifel announced this project - he led this development in 1958. Despite his revelations, the US government never officially acknowledged the work on this project. The nuclear arms race between the USSR and the USA led to the fact that both sides carried out many nuclear explosions in space and in the upper atmosphere. The next plans were to explode nuclear devices on the Moon. However, in 1959, the US plan to deliver a nuclear charge to the Moon, which was already being closely developed by the United States, was canceled. The real reasons were never announced, but it can be assumed that, firstly, the United States feared a negative reaction from society, and secondly, if the launch were unsuccessful, it could pose a serious danger to the population. Another argument was the possible consequences of radioactive contamination of large areas on the Moon.
It is not surprising that the USSR also planned to deliver a nuclear weapon to the Moon and detonate it there. When the Soviet Union created the Lunar Program, it had several points: the first was to reach the surface of the Moon itself, the second and third were to send probes to the far side of the Moon for detailed photography of the surface, and the fourth stage of the project was a direct nuclear explosion on the Moon. After detailed study and even creation of models, one of the authors of the Soviet atomic and hydrogen bomb, Academician Zeldovich, was the first to propose abandoning further work on the project of detonating a nuclear charge on the Moon: given that peaceful space exploration was declared everywhere, this idea did not fit into these statements. In addition, the authors of the project faced the same security issues as the Americans.
Despite this ending to the lunar nuclear programs, the question remains - what would have happened if these plans had been implemented? And if the plans were even more grandiose - would all the nuclear weapons be enough to push the Moon out of its orbit?
Depending on where a nuclear detonation occurred that could dislodge the Moon from its orbit, it would require an explosive device with a yield of 10 billion to 10 trillion megatons of TNT. The most powerful nuclear bomb ever detonated is the Soviet Tsar Bomb, which had a yield of 57 megatons of TNT. Now the entire world nuclear arsenal is approximately 7,000 megatons. Therefore, even if you explode the entire world stock of nuclear weapons on the Moon at the same time, this will not only not destroy it, but will not have any effect on the satellite of our planet at all. Unless a huge crater forms on the lunar surface and, due to the lower lunar gravity, thousands of tons of lunar dust will fly into space.
The Moon is constantly moving away from the Earth. The receding Moon pulls with it part of the Earth's water, which leaves its natural position, creating bulges invisible to the naked eye at each end of our planet. As the Earth rotates, these thickenings of water have their own effects on the Moon, making the increase in its orbit even faster. On average, the moon moves away from the Earth by 3-4 centimeters every year.
Life without the Moon would be somewhat strange in the short term, and disastrous in the long term. If the stabilizing influence of the Moon disappears, the Earth will begin to sharply change the tilt of its axis. This will lead to inconsistent seasons. In the long term, the Earth's axis of rotation may generally change significantly, as happened with Uranus, which does not revolve around the Sun like all the planets, but spins on its side, like a rolling ball.
