AI-Driven Seismic Scan Reveals Six Hidden Deep-Earth Patches

A study using deep learning to analyze over 2 million earthquake records (1990–2024) identified about 174,900 PKP precursor signals and mapped six previously undocumented deep-mantle regions (B1–B6) near the core–mantle boundary, suggesting large, connected pockets of heterogeneity likely tied to ancient subducted material and thermochemical piles. The findings, published in the Journal of Geophysical Research: Solid Earth, refine our view of mantle dynamics and could impact our understanding of earthquakes, volcanism, and tectonics, while calling for higher-resolution follow-up studies.

AI Reveals Six Hidden Deep-Mantle Structures Beneath Earth

AI-assisted analysis of more than 2 million earthquake recordings (1990–2024) identified 174,929 high‑quality PKP precursor signals and unveiled six previously undocumented deep-mantle zones (B1–B6) near the core–mantle boundary. The expanded dataset shows that these small-scale structures may connect into larger belts, likely shaped by subduction and thermochemical processes, with broad implications for mantle convection, volcanic activity, and Earth's magnetic field. The researchers call for higher‑resolution, multi‑wave studies to refine deep-Earth models.

Scientists Discover Enigmatic 20-Kilometer Structure Beneath Bermuda Triangle

Scientists discovered a massive, 20-kilometer-thick, low-density rock formation beneath Bermuda, challenging traditional island formation theories by suggesting a deep mantle origin linked to ancient volcanic activity and deep carbon-rich mantle processes, which helps explain Bermuda's persistent elevation and unique geological history.

"Beneath Our Feet: The Vast Hidden Ocean"

A massive reservoir of water has been discovered deep beneath the Earth's surface in the transition zone, estimated to contain three times more water than all the oceans on the planet's surface. This water is trapped inside a rock called ringwoodite, which forms under intense pressure and can contain up to 1.5 percent water. The discovery suggests a whole-Earth water cycle and may help explain the abundance of liquid water on the planet's surface.

Vast Subterranean Ocean Holds More Water Than Earth's Surface

Scientists have discovered a massive ocean hidden beneath the Earth's crust, stored in a rock called ringwoodite. This water, three times more than what is found in the oceans on the surface, is in a sponge-like state within the mantle rock. The findings suggest a whole-Earth water cycle and may help explain the abundance of liquid water on the planet's surface. This discovery adds to a series of recent scientific revelations, including the identification of a black hole pointing towards Earth, a hole in the sun, the rediscovery of a missing continent after 375 years, and the uncovering of a new ecosystem beneath volcanic crust.

Vast Subterranean Ocean Holds More Water Than Earth's Surface

Scientists have discovered a massive ocean hidden beneath the Earth's crust, stored in a rock called ringwoodite. This water, three times the amount found in the Earth's oceans, is held in a sponge-like state within the crystal structure of ringwoodite. The findings suggest a whole-Earth water cycle and may help explain the abundance of liquid water on the planet's surface. This discovery adds to a series of recent scientific revelations, including the detection of a black hole pointing towards Earth and the identification of a missing continent after 375 years.

"Vast Subterranean Ocean Holds More Water Than Earth's Surface"

Scientists have discovered a massive ocean hidden beneath the Earth's crust, containing three times more water than in the oceans on the surface. The water is stored in rock known as ringwoodite, which acts like a sponge, soaking up water. The discovery of the ocean was made after studying earthquakes and discovering that seismometers were picking up shockwaves under the surface of the Earth. The findings suggest a whole-Earth water cycle, which may help explain the vast amount of liquid water on the surface of our habitable planet.

"Vast Subterranean Ocean Holds More Water Than Earth's Surface"

Scientists have discovered a massive ocean hidden beneath the Earth's crust, stored in rock known as 'ringwoodite'. The rock acts like a sponge, soaking up water, and can contain a lot of water under conditions of the deep mantle. If the rock contained just 1% water, it would mean that there is three times more water under the surface of the Earth than there is in the oceans on the surface. This discovery may help explain the vast amount of liquid water on the surface of our habitable planet.
