Colossal volcanic eruptions like the kind that may have obliterated the dinosaurs more than 65 million years ago are caused by mantle plumes that rise from shifting underground mountains deep within the Earth's mantle, new research led by University of Wollongong (UOW) geophysicists and statistical scientists has revealed.

The study has revealed that giant volcanic eruptions are connected to moving BLOBS. Reconstructing mantle convection from 1 billion years ago, the authors discovered that eruptions usually occur directly above or close to BLOBS, with the mantle plume gently tilting as it rises. Computer models show that volcanic hotspots like Hawaii tend to sit above areas where BLOBS have been located as they slowly move over millions of years.
