Scientists Link Cataclysmic Volcanic Eruptions to Mysterious Continent-Sized BLOBS Deep Within the Earth – The Debrief

New research has traced the origins of some of Earth s most powerful volcanic eruptions to mysterious continent-sized structures deep within our planet.

These formations, known as BLOBS short for Big LOwer-mantle Basal Structures are providing scientists with a deeper perspective on the geological processes uniting activity in Earth s lower mantle to potentially cataclysmic surface events.

The new research, published in Communications Earth and Environment, combines seismic data and geodynamic modeling to reveal how giant columns of hot rock, known as mantle plumes, arise from these massive structures, revealing them as the driving force behind surface eruptions.

Offering the strongest evidence yet that Earth s most destructive volcanic events, including those linked to extinctions, are triggered by interactions between BLOBS and mantle plumes, the new study traces their origins to areas more than 2,000 kilometers underground.

Well that’s news to me.
