New structures deep beneath the surface of the Earth found with seismic data

Researchers have recently discovered massive structures that lie between the heart and mantle of the Earth deep underneath the Pacific Ocean. Beneath the Earth’s surface, the systems go as deep as 2900 km.

Doyeon Kim and his colleagues from the University of Maryland analyzed data from hundreds of major earthquakes only to discover a new structure in the South Pacific Ocean under the volcanic Marquesas Islands.

The network, defined as a region of ultra-low speed (ULV), is about 1000 kilometers in diameter and about 25 kilometers thick, Kim says.

An earthquake can cause seismic waves beneath the surface of the Earth which can travel thousands of miles. Measuring the time and amplitude of these echoes will expose physical sub-surface properties and disclose structures.

Although the findings were largely limited and it was possible to illustrate the surface landscape in a “piecemeal way.” The structure’s construction is still a mystery, as well.

Between 1990 and 2018, as many as 7,000 records of seismic activity were analyzed around Pacific Ocean basin.

The researchers noted that their finding may likely provide an opportunity to better understand the processes that have occured over the years that helped in the evolution of the planet over time.
