Seismologists Declared Life on Earth Was Facing Threat Due to Catastrophic Super-Volcano

Feb 14, 2013 12:35 IST

Seismologists in the second week of February 2013 declared that life on our planet was facing threat because of the catastrophic super-volcano which would erupt anytime in 200 million years. The seismologists explained that around two heaps of rocks which are like the size of continents, were crashing against each other as they shift under the mantle of the Earth, i.e., 2900 km below Pacific Ocean.

Seismologists also explained that beginning of any of huge eruptive events could lead to gigantic destruction on the Earth. This mechanism would lead to huge plume eruptions but these would happen somewhere in 100 million to 200 million years time duration.

The study conducted revealed that the activity created zone of partly molten rock which was that of the size of Florida and this would cause massive eruptions in the times to come.
 
Hotspot plume super-volcano eruptions during previous 2 million years at Yellowstone caldera of Wyoming led to huge landforms. For example, gigantic flood basalt eruptions created huge provinces such as Pacific Northwest’s Columbia River basalts some 17 to 15 million years ago.

Since early 1990s, scientists knew about existence of thermochemical piles, which were that of the size of continents, sitting on top of the Earth’s core and below most of the volcanic hotspots of the Earth.
