On April 21, 2019, YouTube user B. Attila, who lives in an area called Kazincbarcika in Hungary, uploaded two videos with trumpet sounds he recorded:
Hungary has never been famous for particularly strong earthquakes, so the registration of such a phenomenon there looks strange and alarming. Furthermore.
On March 28, about 500 kilometers from the Hungarian Kazincbarciki, trumpets appeared in Romania, in the area of the so-called Vrancea zone, to which we even dedicated a special material:
Of course, no one really knows what the “trumpet sounds” are connected with, but most often they are associated with some kind of processes in the lithosphere, so sometimes, as it happened in the spring of 2018 in Hawaii, they can portend earthquakes.

For Europe, even 6.0 will be a local, at least, a disaster, since in places where 6.0 is often all buildings and structures are built, taking into account possible seismic events, at the same time in Paris and Warsaw over the centuries people have piled stones on each other and at the slightest point all these "monuments of Gothic architecture" will fall on your head. Not to mention the new buildings of the 20th century from the times of the Warsaw Pact and the USSR.
No less disturbing things are happening on other continents.

Since it is not known for certain that the sources of such sounds are some processes in the lithosphere, it is impossible to make a reliable correlation between the strength of sound and the time after which an earthquake will occur. That is, the stronger the sound, the less time remains before the seismic shock.
However, if there is such a correlation, then something should happen in Mexico in the near future, because what the people living there recorded sounds truly apocalyptic and most likely portends a large earthquake.
