Detecting strange tectonic plates at a depth of 660km in the South Pacific

For the first time in the history of geology, American scientists discovered the presence of a tectonic plate of Earth's Mantis, in the southern Pacific region.

"Using specialized imaging equipment, we captured ancient tectonic plates millions of years ago, beneath the Tonga Islands in the southern Pacific. This is an area with up to 90% of seismic movements. At a depth of 500km on Earth , " geologist Jonny Wu of the University of Houston told The Guardian.

Geologist Jonny Wu discovered that this plate is located in the transition area of ​​the Manti , between the upper Manti and the lower Manti. Specifically, at a depth of up to 660km.

The discovery was officially announced during the joint conference between the Japan Geological Federation and the American Geological Society in Tokyo (Japan) on 23/5/2017.

Explaining this finding, the geological group of the University of Houston (USA) explained on Zmescience that:

The Manti (also known as Mantle) has a stone shell about 3,000 km thick, accounting for about 70% of Earth's volume.

At the shallow points of the mantle contains molten products (just below the crust). As they move, the crust also shifts, causing tectonic plates to stretch, causing cracks in the ocean floor, causing magma eruptions from the Manti.

When two tectonic plates collide with each other , they happen to be a phenomenon that geologists call subduction . After moving thousands of kilometers over millions of years, the two swords created collided at the sinking point.

They move in the direction of attracting each other and subduction occurs, whereby an array moves down below another plate and sinks into the Manti. This is the tectonic plate that scientists at the University of Houston (USA) have discovered.

In addition, the displaced crust also causes other natural disasters such as earthquakes, volcanic formations, underground mountains .

This event is consistent with the intense Vitya z earthquakes in the depths between Fiji and Australia.

This finding shows that our scientific understanding of shells and coatings is limited. Just below the surface of the Earth, at a depth of thousands of kilometers geological activities also contain many confusing things, challenging the constant discoveries of people.
