American geologists have harshly criticized the idea of a number of experts that in order to prevent volcanic eruptions, it is possible to fill their vents with concrete.
Concrete has a melting point in the region of 1500 degrees Celsius, while lava only reaches 871 degrees. In this regard, a myth has arisen that if you pour enough concrete into the vent, it can theoretically be blocked.
However, in this case, the volcano is deprived of the possibility of natural gas release in order to relieve the accumulated pressure. As a result, it changes from a good, slow-flowing volcano to an explosive volcano. In other words, it will explode with even more pressure when the time comes.
At the same time, the concrete poured into the vent easily disperses. Rising dust would lead to deadly diseases, including lung cancer, writes planet today .
