Known as the Indian Ocean Geoid Low (IOGL), this region experiences weaker gravitational forces than anywhere else on Earth, ...

The IOGL spans about 2 million square miles (about two-thirds the size of the lower 48 US states) and is more than 600 miles below Earth’s crust, according to Science Alert. ...

Officially known as “the Indian Ocean geoid low” (IOGL), it is informally referred to as the Indian Ocean gravity hole. At the IOGL, the sea level dips by a staggering 328 feet ...

The Indian Ocean geoid low (IOGL) is a 1.2 million-square-mile (3 million square kilometers) depression found 746 miles (1,200 kilometers) southwest of India.

The IOGL, then, is an area of low mass below that blob on the map — caused by the rising rock we mentioned earlier — and the resulting slight downtick in gravity. Related Stories.

The IOGL, as Pal and Ghosh argue in their latest paper, likely took its current shape roughly 20 million years ago as a result of plumes of hot, ...

Also known as the African blob, this geological feature that helped form the IOGL likely came from oceanic slabs from the Tethys Ocean, a “ghost ocean” that was possibly in place before India ...

The study, published in Geophysical Research Letters, proposes that the IOGL comprises slabs from the Tethys Ocean, a long-lost sea that plunged into the depths of the planet millions of years ago ...

Now, a study published May 5 in the journal Geophysical Research Letters suggests the IOGL was caused by low-density magma that was pushed into the Indian Ocean by the sinking slabs of an ancient ...

An enormous gravity hole lying in the Indian Ocean has been discovered by researchers at the Indian Institute of Science. The sea level only dips because of a gravitational tug-of-war just off the ...

Consequently, the IOGL emerged as an area of low mass, attributed to the upwelling rock, resulting in a slight downtick in gravity at that specific location.
