Why did the death hole appear?

Find the cause of the death and the danger of death.

As reported, a giant 40-meter "death hole" suddenly appeared in Perm, Russia, leaving some 2,000 people in the house or evacuated to ensure their safety.

New death craters appear in Russia

According to experts, death can appear anywhere, anytime that we can hardly expect. With a terrifying subsidence, death can appear before your eyes "in the blink of an eye".

Find out what happens and measure the danger of death.

Death death is a phenomenon of geological subsidence in areas with special geological structure: soft ground, less stable, easily eroded or hollowed out, so any subsidence can be subsided. when.

The phenomenon is due to the underground structures of the interior, the dome of the underground cave is lost, collapsing, dragging the upper land such as trees, houses .

According to experts, it is the groundwater that flows through the hard, soluble soil areas such as limestone, carbonate, salt . which erode the solid surface layer, creating holes and underground compartments. As a result, deep pits appeared, pulling the surface layer collapsing inside.

The image of the death pit appeared between San Antonio and Guatemala on February 23, 2007.

A lot of death holes have appeared in the world. It can be mentioned as the death hole appeared between San Antonio, north of Guatemala City on February 23, 2007, 100m deep or death in Berezniki (Russia) in 1986, 40m wide, 80m long, 200m deep, dragging into number of stones and objects above.

Many experts have explained this phenomenon. Experts said that small earthquake aftershocks or heavy rain can also cause the rock layer to suddenly disintegrate into many pieces underground, causing unexpected subsidence.

In addition to geographical factors, activities such as construction of infrastructure, bridges, mining . are also factors contributing to this phenomenon.

Several advanced technologies have also recently launched modern machinery to broadcast land-based radar and process scientific data to measure and detect the subsidence of the subsidence.

When you notice that the area has vibrations caused by an underground explosion, creating cracks or some signs such as erosion surfaces, sunken soil, leaning trees, doors, and closed windows, you can report to yourself. Local rights and move away from that location because most likely, subsidence will happen.
