In the past, the Altai Mountains were much higher than they are now. They are very old, though not as old as the Ural Mountains. However, around 200 million years ago they began to collapse, and have since become much lower.
Despite the fact that the process of their formation ended a long time ago, the southern spurs of the Altai Mountains continue to grow due to the collision of two lithospheric plates, the Eurasian and Hindustan. They grow, however, slowly, a couple of centimeters a year, give or take.
Earthquakes periodically occur here , and sometimes quite strong. In 2003, the Chuya earthquake that occurred in these parts became the third strongest of all that occurred in Russia from 1991 to 2020. Its magnitude was 7.3 points, and after it followed as many as 140 aftershocks, that is, aftershocks.
The air in the Altai Mountains is still one of the cleanest not only in Russia, but throughout the world. This is largely due to the fact that this remote region has not yet been mastered by industry.
The Altai Mountains are located on the territory of four countries at once - Russia, Mongolia, Kazakhstan and China. The largest parts of them belong to Russia and China, and the Russian-Kazakh border runs along the aforementioned Belukha mountain.
