Scientists Discover Donut-Shaped Structure in Earth's Outer Core

New seismic wave analysis reveals a unique region at the equator with implications for Earth's magnetic field.

The donut-shaped region is located at the top of the Earth's outer core, near the equator.
Seismic waves travel 2% slower through this region, indicating a higher concentration of lighter elements.
This finding could help scientists better understand the dynamics of Earth's magnetic field.
Researchers used a novel approach, analyzing seismic wave similarities hours after earthquakes.
The study suggests more heat transfer in this region, affecting the outer core's convection currents.
