Indo-Australian Plate Broken Apart. Now Two Plates???

Hi All. It seems the Indo-Australian Plate may no longer be one plate. It may at this very moment be two plates each going their own way. Take Care…Don in creepy town

In a report published in the most recent issue of Earth and Planetary Science Letters (vol. 133), the scientists say they have confirmed that the Indo-Australian Plate--long identified as a single plate on which both India and Australia lie--appears to have broken apart just south of the Equator beneath the Indian Ocean. The break has been underway for the past several million years, and now the two continents are moving independently of one another in slightly different directions.

Scientists have known that for some 50 million years, the Indian subcontinent has been pushing northward into Eurasia, forcefully raising the Tibetan Plateau and the Himalayan Mountains. The new research suggests that starting about 8 million years ago, the accumulated mass became so great that the Indo-Australian Plate buckled and broke under the stress.

"The result of this critical stage in the collision between India and Asia is the breakup of the Indo-Australia Plate into separate Indian and Australian plates," Jeffrey Weissel, a scientist at Lamont-Doherty, Columbia's earth sciences research institute in Palisades, N.Y., said in an interview.
