Giant ‘Gravity Hole’ in Indian Ocean possibly caused by ancient sea that sank millions of years agoBy David Propper

A huge, mysterious so-called “Gravity Hole” underneath the Indian Ocean might have been formed from the remnants of an ancient sea, according to a new study.
Researchers recently offered the possible origins of a massive expansive depression at the bottom of the sea — known as Earth’s most notable gravity anomaly.
The new study makes the case that the Indian Ocean geoid low (IOGL) is made up of slabs from the long-lost Tethys Ocean that sank within the planet millions of years ago, according to Scientific American.
The IOGI spans about 2 million square miles and is more than 600 miles below Earth’s crust, according to Science Alert.
And according to the new study published in Geophysical Research Letters, it could have been caused when the Tethyan slabs “perturbed” the African Large Low Shear Velocity province, which is also known as the “African blob” leading to plumes beneath the Indian Ocean.
