Volcanic super-eruptions

04 Jun 2020

Volcanic super-eruptions associated with Yellowstone hotspot track announced

Volcanic super-eruptions have been some of the most extreme events ever to affect Earth's surface. Although these explosions eject enormous volumes of material --at least 1,000 times more than the 1980 eruption of Mount St. Helens -- and have the potential to alter the planet's climate, few super-eruptions have been documented, according to ScienceDaily report.
