Geologists have studied the Taupo supervolcano in New Zealand to understand the causes of the eruptions of all the supervolcanoes.
The last eruption of Taupo occurred 26,500 years ago. Its strength reached 8 points, and 530 cubic kilometers of magma were ejected from the vent. To understand the causes of this disaster, volcanologists have analyzed sediments around the volcano.
Scientists have found that after each small or medium-sized eruption, volcanic deposits rose higher and higher to the earth’s surface. Moving through cracks and cavities, magma accumulated and provoked individual outliers. When the amount of magma near the surface reached a critical level, that super-incarceration happened.
Scientists do not yet know what time magma needs to fill the cavities and create conditions for a new eruption. But the latest data helped to pinpoint the causes of the super-explosions. The researchers believe that the results will provide an opportunity to accurately predict the future super-eruption of volcanoes of the Yellowstone type and not to keep the townsfolk in the dark.
