Giant tectonic plate below the Indian Ocean has been divided into two

The giant tectonic plate located under the Indian Ocean is breaking and could be divided into two parts. This is what a study published in the journal Geophysical Research Letters reveals.

Called Indo-Australian, the plate has followed a slow pace in its separation. The speed at which the phenomenon would occur is approximately 1.7 millimeters per year. For humanity, it would have to take another million years for there to be a distance of 1.7 km.

For comparison, the marine geoscience researcher at the Institute of Earth Physics in Paris points out that the Dead Sea, in the Middle East, has its fault moved approximately 0.4 cm per year – which would represent more than twice the phenomenon in question.

San Andreas, in Callifornia, moves 1.8 cm annually, which is more than 10 times Indo-Australian. Even if it divides at a speed well below that of the others, it is enough for scientists to detect the situation

“It is not a structure that moves quickly, but it is still significant compared to others that are present on the planet. It is like a puzzle. It is not a uniform plate. There are three structures together that move in the same direction. ”

The study reveals that the creation of this rupture happens due to the emergence of a new oceanic crust, which cracked the plate because of the curvature of the Earth.

It is worth remembering that the shock of plate tectonics is the reason for the formation of earthquakes and tidal waves in the world. However, a phenomenon of the type as a consequence of the Indo-Australian movement is expected to be only 20,000 years from now.
