Scientists uncover unusual undersea structures beneath the Pacific Ocean

New research from the California Institute of Technology and ETH Zurich has uncovered unusual structures in the Earth's mantle, suggesting a "lost world" beneath the Pacific Ocean. These findings challenge previous understandings of tectonic plate distribution. Scientists used a new method to analyze earthquake waves, revealing unexpected locations of tectonic plate remnants. These areas are often colder and differ in composition from known plate boundaries, indicating that such anomalies are more widespread than previously believed. The researchers are uncertain about the origins of these anomalies, which may include ancient materials or iron-rich rocks formed over billions of years. Further exploration is needed to understand these discoveries fully.
