Scientist detect rare boomerang earthquake while examining quakes under the Atlantic ocean

Scientists from the University of Southampton and Imperial College London found a rare type of an earthquake, known as a boomerang, while carrying out a study examining quakes under the Atlantic ocean.

They found out that in case of the boomerang earthquakes, the rupture initially travels away from the original break but returns at higher speeds.

Earthquakes usually occur when pressures build up between two pieces of Earth’s crust and it is released eventually. As a result of this, tremors are felt. If the intensity is high, the earthquakes can cause serious large scale damage.




A boomerang earthquake can do more damage than the normal quakes as the high speed of the returning wave increases the area of destruction. What happens is while coming back, the rupture the seismic sound barrier, and due to which it creates an ultra-fast earthquake.

The study published in Nature Geoscience reveals that the team recorded a magnitude 7.1 earthquake in the Atlantic Ocean in 2016 and it could have been this rare type of quake. They detected it using underwater seismic sensors.
