The Indo-Australian lithospheric plate, located beneath the Indian Ocean, is split into two parts. This is stated in a study published in the journal Geophysical Research Letters. Scientists have been observing this process since 2012, when two powerful earthquakes occurred in the area of Indonesia.
According to the calculations of scientists, the plate splits at a rate of about 1.7 mm per year, ie in a million years the depth of the fault will be 1.7 km. And by geological standards, this is far from super speed. For example, the Dead Sea Fault in the Middle East is growing about twice as fast, while the San Andreas Fault in California is 10 times faster. So the whole plate will crack in tens of millions of years.
