Scientists have captured the best resolution photos of the Earth’s innards.
The core-mantle border is one of the Earth’s least understood sections, according to a study published by a joint research group.
By focusing on a massive mantle plume beneath the Hawaiian archipelago, they made interesting insights about Earth’s geology, according to Interesting Engineering.
The research, which was published in the journal Nature Communications, employed new imaging techniques to collect information about what lies 3,000 kilometers (1,864 miles) beneath the Earth’s surface – in an ultra-low velocity zone (ULVZ).
For a long time, scientists have used seismic waves to observe this region deep within the globe. However, the photographs they received were fuzzy and difficult to decipher. Our understanding of this region inside Earth may change as a result of these new high-definition photographs.
“These are the most fascinating and complex of all Earth’s deep inner features,” said geophysicist Zhi Li of the University of Cambridge, a study contributor.
He went on to say, “We’ve now obtained the first substantial evidence to indicate their internal structure — it’s a tremendous milestone in deep Earth seismology.”
To get a crisp image, the researchers constructed new computer models that rely on high-frequency data from the ultra-low velocity zone. Scientists were able to get a “kilometer-scale look at the rock pocket” with higher resolutions than could be obtained using existing methods.
Now, scientists plan to investigate the border between Earth’s iron-nickel core and the surrounding mantle using the same technique. As a result, new pathways for studying plate tectonics, volcano creation, and other earthquake-related phenomena may open up.
Increased iron in ultra-low velocity zones is thought to be responsible for the extra density that may be seen in seismic wave patterns. Furthermore, many scientists believe that ultra-low velocity zones and volcanic hotspots, such as those in Hawaii and Iceland, are linked. Scientists may be able to better analyze if these hotspots are responsible for volcanic outbursts using this new technique.
