Volcanic eruptions News

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.

The study found that there was less volcanic activity in Iceland when glacier cover was more extensive and as the glaciers melted volcanic eruptions increased due to subsequent changes in surface pressure.

Enormous eruptions trigger El Nino events by pumping millions of tonnes of sulfur dioxide into the stratosphere, which form a sulfuric acid cloud, reflecting solar radiation and reducing the average global surface temperature.

Evidence of these changes is found in many parts of the Southern Hemisphere and in different paleoclimate archives, but what prompted these changes has remained largely unexplained.

The Triassic extinction, one of the largest mass extinctions of animal life on record, was proceeded by the dinosaur era.

The researchers studied rocks filling one of the largest preserved impact structures on the planet, located in Sudbury, Ontario, Canada. 

Previous studies have suggested it came about due to an eruption associated with a plume that now lies directly below Reunion Island in the Indian Ocean, about 66 million years ago.

Volcanic eruptions in Indonesia in recent days have forced the closure of two airports and disrupted some flights to the holiday island of Bali, officials said Wednesday. 

Andrea Dutton from University of Florida and colleagues from University of Michigan in the US utilised a new technique of analysis to reconstruct Antarctic ocean temperatures that support the idea that the combined impacts of volcanic eruptions and an asteroid impact brought about one of Earth's biggest mass extinctions 66 million years ago.

A study shows that acid fog can dissolved rocks on the red planet.

Mount Zao is 1841 metres high and located between Miyagi and Yamagata prefectures. 

Did you find it hard to believe the climate scenario featured in the disaster movie 'The Day After Tomorrow'? Now, a researcher has produced a scientific study of the scenario.

Scientists did a research to better understand how big volcanic eruptions, which can trigger a shortage of rainfall, can impact rivers.
