Earth’s lowest “gravity hole,” a mysterious depression in the Indian Ocean that experiences less gravity than the rest of the planet, is likely due to plumes of magma under the Earth’s crust, a recent ...

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 ...

Deep below the Indian Ocean, there’s a giant “gravity hole” over one million square miles in size, a depression in the Earth’s crust that has puzzled scientists for decades. While it’s technically not ...

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 ...

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 ...

Beneath the Indian Ocean lies a gravitational enigma — a vast depression where the ocean surface dips 106 meters lower than surrounding areas. Known as the Indian Ocean Geoid Low (IOGL), this anomaly ...

There is a place on Earth where the laws of gravity as we know them do not apply. Officially known as “the Indian Ocean geoid low” (IOGL), it is informally referred to as the Indian Ocean gravity hole ...
