Scientists mystified by massive structures found deep beneath the Pacific Ocean

Scientists use seismic waves from earthquakes to study Earth ’s deep interior.

Using innovative technology to analyze seismic waves, researchers have identified massive structures that challenge fundamental theories about how our planet formed and evolved.

The most striking finding emerged beneath the western Pacific Ocean , where researchers identified a massive anomaly between 900 and 1,200 kilometers depth.

This suggests that Earth ’s mantle may be more heterogeneous or varied in composition than previously thought.

The resolution of seismic imaging continues to depend on the global distribution of earthquakes and seismic stations.

While FWI provides more comprehensive data, it requires enormous computational resources and makes certain assumptions about wave propagation through Earth 's interior.
