Explosive volcanic eruptions can result in significant loss of life and property. Scientists in Australia identified 'blobs' located about 1,200 miles beneath the Earth's surface, which are believed to be responsible for these massive eruptions. These blobs, stretching deep in the mantle, can trigger plumes of hot rock that result in destructive eruptions. Such eruptions can have catastrophic effects, including sudden climate changes and mass extinctions. The research team modeled mantle convection, revealing the nature of blobs compared to surrounding mantle rocks, which may not move in the same way.
Explosive volcanic eruptions can kill hundreds or thousands, burying them under lethal pyroclastic flows. Scientists have identified 'blobs' about 1,200 miles below as a potential cause.
Blobs span continental lengths and are 100 times taller than Mount Everest, sitting at the bottom of the mantle above the molten outer core, spawning plumes of hot rock.
Giant volcanic eruptions can lead to sudden climate change and mass extinction, having triggered the largest extinction event on Earth, the Permian-Triassic extinction 252 million years ago.
