Unraveling the Mystery of the Indian Ocean's "Gravity Hole"

Scientists have been puzzled by the Indian Ocean Geoid Low (IOGL), also known as the "gravity hole," which is a gravity anomaly in the Indian Ocean. New research suggests that the anomaly may be caused by plumes of magma in the Earth's mantle, which were stirred up when the Tethys plate slipped under the Earth's surface and into the mantle as the Indian plate drifted towards Asia. The study provides insights into the origins of this peculiar phenomenon, although predicting the exact geological landscape of the Earth millions of years ago remains challenging.
