If you look at a map of Earth's gravity, you will see a huge blue spot south of India, indicating a region where gravity is weaker than average. This spot is called the Indian Ocean Geoid Low (IOGL), and it is the largest gravity anomaly on our planet.
A gravity anomaly is a difference between the actual gravity measured at a location and the theoretical gravity expected for a perfectly smooth and spherical Earth. But Earth's gravity isn't perfectly uniform and variations in mass distribution beneath the surface cause fluctuations in gravitational pull.
Gravity anomalies can be caused by variations in the density and thickness of Earth's crust, mantle and core. Denser areas have a stronger pull, while less dense regions exert a weaker one. These anomalies affect the shape of the ocean surface, which is not flat but follows the contours of Earth's gravity field. This shape is called the geoid, and it is what we would see if we removed all the effects of tides, winds and currents from the ocean. The geoid is often visualized as a potato-like shape, with bumps and dips corresponding to high and low gravity regions.
The IOGL is one of the most prominent dips in the geoid, covering an area of about 3 million square kilometers, almost the size of India itself. Due to the low gravity there, the sea level over the IOGL is up to 106 m (348 ft) lower than the global average. That means if you were to sail across the IOGL, you would be closer to Earth's center than anywhere else on the ocean.

Due to the world's largest gravity hole, the sea level in a large part of the Indian Ocean is up to 106 m (348 ft) lower than the rest of the world. We have just understood what causes this huge 'black hole.'gravity hole indian ocean geoid low iogl fbShown here in deep blue, the Indian Ocean Geoid Low (IOGL) is the world's largest gravity hole.Image: ESA/HPF/DLR
During the IGY (which lasted more like 20), it was first noticed that the surface of the ocean had bulges of a sort, due to the differences in density of strata below the seafloor. :^) For good measure, I've included the usual Potsdam Gravity Potato keyword topic list. :^)
So THAT’S WHAT HAPPENED TO MH370!................
If the gravity in that region is lower, then why is the sea level in that area 106m lower? Shouldn’t it be higher?
I remember reading that there is an entire city somewhere off the coast of the southern tip of India that wasn’t found until recently by divers...............
It’s because on the other side of the Equator, everything’s opposite! /rimshot
It seems odd, but it’s correct.
From Brave AI:
Lost City Off India
An underwater city off the coast of the southern tip of India was discovered near Mahabalipuram, also known as Mamallapuram. This discovery was made possible after a tsunami in 2004 revealed ancient ruins that were previously covered by silt and sand. Archaeologists found structures such as a temple, stairs, and walls, confirming local folklore about the existence of a lost civilization. Further exploration using sonar technology has since confirmed the submergence of a large area that could be the remains of a submerged township.
Another significant underwater discovery in India is the Gulf of Cambay site, where marine archaeologists found huge geometrical structures using sonar scanning technology. This site, thought to be around 9,500 years old, could predate the oldest known remains in the subcontinent by more than 5,000 years.
Additionally, underwater archaeologists are searching for the foundations of the city walls of Dwarka, an ancient city said to have sunk beneath the Arabian Sea, to prove its existence.
AI-generated answer. Please verify critical facts.
There’s Dwarka (actual ruins down there) in the west, there’s the submerged land bridge out to Sri Lanka, and during the Boxing Day tsunami, a submerged city off the east coast was temporarily visible. :^o

Wow, your Brave search term must have been way better than mine. :^)
From article:
the reason is that higher gravity regions pull ocean water toward them and away from lower gravity regions, causing the latter to have less water and consequently lower sea levels. Also, water, being nearly incompressible, cannot be pulled down by higher gravity regions since there is no downward direction for it to move. Instead, water accumulates over areas with high gravity.
I was wondering that too
So gravity is weaker and the ocean level is lower? That sounds counter intuitive to me. I’d think stronger gravity would pull it closer to the core and weaker would allow it to expand out.
Woke Physics?
Until January, 2025, one of the “densest” areas on Earth, indeed in the known universe, was Washington DC, and the surrounding areas.
So you are mainlining that this is a permanent Low Tide spot?
So if you go swimming in the Indian Ocean are you more buoyant?
And by the way when I looked up the way to spell buoyant and the definition I found it said, “Lighthearted; gay.
“in a buoyant mood.””
I’m NEVER going for a swim in the Indian Ocean!!! I don’t WANNA be gay!
