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 ...

The Indian Ocean holds the lowest gravity anomaly on Earth, a vast and subtle depression in the planet’s gravitational field ...

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 ...

It is found in the depths of Indian Ocean and named as the gravity hole or Indian Ocean geoid low, an anomaly on earth where gravity is said to be weaker, and levels of sea dip by more than 328 feet ...

In the Indian Ocean, there is a place where the laws of gravity seem to falter—a gigantic depression in the Earth’s geoid where the gravitational force is weaker than normal, causing the sea level to ...

The Indian Ocean "gravity hole" is Earth's deepest geoid low. Its weak gravitational pull makes sea levels here 348 feet lower than average, creating a 1.2-million-square-mile anomaly southwest of ...

A recent study published in Geophysical Research Letters has uncovered new insights into one of Earth’s most puzzling anomalies—a massive gravity hole beneath the Indian Ocean. The phenomenon, known ...
