The deepest earthquake ever recorded

The earthquakes or earthquakes depending on their depth are divided into superficial, which are those that occur less than 70 kilometers below the surface, intermediate to those that originate between 70 and 300 kilometers and deep that are those that they take place more than 300 kilometers away.

The vast majority of earthquakes occur less than 100 kilometers under the ground, the rarest are deep earthquakes whose origins have been the subject of scientific debate for almost a century and even more enigmatic are those that occur more than 650 kilometers deep. the so-called bathysism, the word is formed with earthquake and batis which in Greek means deep.

Now a team made up of researchers from the universities of Arizona and Michigan in the United States have detected the deepest earthquake in history, 751 kilometers below the ground, this ultra-deep earthquake was a minor aftershock of a magnitude 7.9 earthquake that shook the island of bonni off Japan in 2015

Seismologists believed that it was practically impossible for earthquakes to occur at such depth in the lower mantle of the earth, so some experts have warned that it is necessary to carry out more studies to confirm if the earthquake was real or not, for now and until not. more studies are done the data indicates that it was real.

Current theory suggests that the upper mantle is composed of olivine, a mineral whose structure stops being stable the greater the depth, this is the key, because from about 410 kilometers deep, other minerals with names also begin to form. complicated like Wadsleyite and ringwoodite that are more and more common the further we go deeper into the earth.

The change from the divine to those other minerals can generate weak points where the matter could deform generating an ultra-deep tremor, however at 660 km this system changes abruptly, the seismic waves around that limit suggest that the rocks below are much denser than those above, where the lower mantle begins, however this ultra-deep tremor detected even lower at 751 kilometers deep in the lower mantle, geologists are still not clear how something similar could have been produced is a mystery that awaits From new research, although scientists believe that it will be difficult for such a deep earthquake to occur again, they undoubtedly believe that it was an extraordinary event.
