The Indian Ocean Geoid Low (IOGL), a significant gravitational anomaly, has puzzled scientists for decades. Research suggests it formed due to interactions between tectonic plates and mantle plumes ...

Add Yahoo as a preferred source to see more of our stories on Google. There is a “gravity hole” in the Indian Ocean — a spot where Earth’s gravitational pull is weaker, its mass is lower than normal, ...

Add Yahoo as a preferred source to see more of our stories on Google. The Indian Ocean Geoid Low spans 1.2 million square miles where a deep gravity anomaly causes the sea surface to sink by as much ...

In 1948, Dutch geophysicist Felix Andries Vening Meinesz was sailing the planet on a gravity survey when he discovered an anomaly in the Indian Ocean. It was a circular depression in the ocean floor ...

For years, researchers have tried to pinpoint how an area deep in the Indian Ocean with lower gravitational pull came to be. A team in India may have figured it out. The area in question is called the ...

Gravity feels steady. You drop a set of keys, and they fall the same way every time. That reliability makes it tempting to picture Earth's pull as uniform. It is not. After accounting for Earth's ...

Researchers think they’ve found the reason for the most significant drop in Earth’s gravity, known as the Indian Ocean geoid low. In this location in the Indian Ocean south of Sri Lanka, our planet’s ...

South of Sri Lanka, the Indian Ocean is home to the planet's lowest gravity anomaly, a large and subtle depression in the gravitational field. Despite the seemingly calm ocean surface, the region's ...

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 possible ...

The Earth's interior is still a mystery to us. While we have sent missions to probe the outer reaches of our Solar system, the deepest boreholes on Earth go down to only a few kilometres. The only way ...

The ground may feel steady underfoot, but the planet is always in motion. While satellites and sensors have mapped the surface in fine detail, what lies beneath remains largely unknown. The crust, a ...

South of India, the ocean surface slumps into one of Earth’s strangest depressions, a gravity hole so deep it has puzzled geophysicists for decades. Now a new reconstruction points to a buried plume ...
