Six Never-Before-Seen Mystery Structures Found Lurking Deep Inside The Earth
What are they?

Researchers have identified six previously unknown structures buried deep within Earth’s interior, marking a significant advancement in understanding our planet’s composition. Using sophisticated machine learning technology, scientists at the Chinese Academy of Sciences analyzed seismic data spanning over three decades to uncover these mysterious formations located near the boundary between Earth’s mantle and outer core.
The breakthrough involved examining earthquake recordings through a new lens. Rather than manually searching through millions of seismic records—a tedious and inconsistent process—the team deployed an artificial intelligence system trained to identify faint seismic signals called PKP precursors. These signals reveal irregularities in Earth’s deep interior by analyzing how earthquake waves scatter when encountering variations in material composition. The algorithm discovered nearly 175,000 such signals, more than ten times the total found in all previous research combined.
The expanded dataset revealed that previously scattered anomalies actually form connected belts of larger structures, suggesting they may be far more extensive than scientists initially believed. Researchers propose these formations could contain ancient material—potentially continental crust, oceanic crust, or remnants from the cosmic collision that created the Moon—pushed deep into Earth through geological processes. The six newly identified zones represent critical targets for future exploration of Earth’s hidden interior.
This research carries practical implications beyond scientific curiosity, as understanding Earth’s internal dynamics helps predict earthquakes and other natural disasters that threaten human populations and infrastructure.
