Due to plate movement, the Pacific Ocean floor is now deep under China

Seismologists have discovered the lower part of the lithospheric plate, which has been uplifted by more than 643 km, beneath northeastern China.

The study explains what happens to water-filled tectonic plates as they move under the continents.

Rice University seismologist Fenglin Niu said that the study has the first seismic images of the upper and lower boundaries of tectonic plates, in particular, the images show a transition zone of the mantle that begins about 410 km from the Earth’s surface and extends for about 660 km.

Many studies show that the plate is actually strongly deformed in the transition zone of the mantle, becomes soft and easily deformed. ” How much the slab deforms or retains its shape matters when we explain whether it mixes with the mantle, if so, how, and what kind of cooling effect it has.

When they meet, tectonic plates collide and crumble, releasing seismic energy. In some cases, this can cause devastating earthquakes and tsunamis, but most seismic vibrations are too weak to be felt by humans without special equipment.

Using seismometers, scientists can measure the magnitude and location of seismic vibrations. Since seismic waves are more active in some rocks and slowed down in others, scientists can observe changes in the bowels of the earth in the same way as a doctor, using ultrasound.

Thus, a group of scientists using a network of seismic stations constructed images of the boundaries of the flooded Pacific plate. They suggest that modern China is now above this plate. The data on the nature of the plates to be extended through the country can explain the nature of seismological changes.
