Nanocrystals could provoke sudden volcanic eruptions, known to history. The corresponding conclusions were made based on the results of the study by a group of scientists led by Danilo de Genova.

Geologists have long debated the causes of sudden volcanic explosions that seemed relatively calm. A new scientific work has shown that particles of microscopic size, which include aluminum, iron and silicon, can be the culprit. We are talking about nanoliths, their size is about 10 thousand times smaller than human hair. Experts have carried out a detailed analysis of the ash ejected by the volcano, having found the presence of these particles there.
The scientists also looked at the properties of magma, which includes trace amounts of silicon oxide. This type of molten mass is characterized by high fluidity, and after cooling it transforms into basalt, reports Planet Today. The experts concluded that the presence of nanoliths in such magma provokes an increase in viscosity, which can lead to a plug effect. As a result, the pressure build-up in the volcano's vent threatens to end in a sudden explosion.
