(ORDO NEWS) — Experts say that eruptions leading to a catastrophe, in fact, can occur much more often than previously thought. Similar conclusions were made after experts studied a very old supervolcano located in Indonesia.
They found that it could remain active for several millennia after the eruption occurs. New data requires that it is necessary to revise forecasts that relate to potentially dangerous events.
Martin Danishik of Curtin University argues that supervolcanoes have erupted only a few times, and there were specific periods of time between these events. But no one can say about what happened on the planet during these periods.
Super-eruptions are considered the most catastrophic events that can happen on our planet. The process provokes the release of a huge amount of magma at a time.
Eruptions of this nature can completely change the climate on Earth, and also cause the beginning of a “volcanic winter”. This is an abnormally cold period that could end in many deaths and dire famines across the planet.
Scientists have analyzed the magma that remained in the supervolcano Toba after the super-eruption that happened 75 thousand years ago.
The results surprised them. It turns out that magma continued to seep into the caldera for about 5-13 millennia after the deadly event. Experts added that such data indicate that the danger does not disappear anywhere even many centuries after the eruption of the supervolcano.
