There is a “gravity hole” in the Indian Ocean — a spot where Earth’s gravitational pull is weaker, its mass is lower than normal, and the sea level dips by over 328 feet (100 meters).

The researchers discovered that 'low-density anomalies'—the presence of lighter materials in the upper to mid-mantle beneath the IOGL—caused the gravity low in this region.

The Indian Ocean "gravity hole" is a region where Earth's mass is reduced, leading to weak gravitational pull, lower-than-average sea levels and a puzzle scientists have only just begun to solve.

At the geoid low’s lowest point, where sea level plunges over 328 feet, is a gravity hole where Earth’s gravitational pull is weaker and its mass is lower than normal.

Science physics planets Earth's "gravity hole" off the Indian coasts has finally been explained. Maybe The Indian Ocean Geoid Low was likely shaped by magma plumes, but something's still amiss By ...

A huge, mysterious so-called “gravity hole” under the Indian Ocean might have been formed from the remnants of an ancient sea, according to a new study. Researchers recently offered the ...

This gravity “hole” may be due to low-density plumes of magma disturbed by the sinking slabs of a former tectonic plate. Neither Earth nor its gravitational field are a perfect sphere.

The formation of Earth's gravity hole goes like this: Roughly 200 million years ago, there was an ancient ocean called Tethys, perched between the supercontinents of Laurasia and Gondwana.

A 'gravity hole' south of India was formed by plumes of low-density magma that rose up from Earth's mantle, according to scientists at the Indian Institute of Science in Bengaluru.
