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 ...

For over seventy years, the Indian Ocean Geoid Low (IOGL) has intrigued scientists as one of Earth’s most unusual gravitational anomalies. Located beneath the Indian Ocean, this mysterious dip ...

South of Sri Lanka, the Indian Ocean’s surface dips in a broad, subtle depression that has puzzled geophysicists for decades. The sea level there sits more than 100 meters below the theoretical shape ...

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 ...

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 ...

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 ...

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 ...
