The InSight’s rover mission has installed its seismometers on the Mars’s surface to monitor the seismological activity since December last year.
The first fluctuations in the soil were recorded on April 6th. This discovery has tremendous potential.
First, it shows that the core of this planet is seismically active. It indicates that the core of Mars is alive and moving.
Second, it found similarities between underground oscillations on Mars and those on the moon. The Apollo mission has also recorded light earthquakes on the surface of the Moon in the past.
But the causes of earthquakes on Mars are different from those on Earth.
Oscillations of the Martian soil are caused by disturbances and collapses in the structure of the planet’s surface, as tectonic plates are absent on this planet.
Thirdly, the analysis of oscillations will help to study the internal structure of Mars. It is known that different rocks reflect oscillations in different ways. Analysis of seismological vibrations will allow scientists to simulate the way the Red Planet is arranged from the inside.
Studying the inner structure of the planet will reveal new facts and knowledge about its early history. So far, there is no other effective way to study the early history of the Red Planet. And the discovery of this marsquake will create a new path to study and research.
This natural accident will provide a ground for discussions and further researches. If it had happened on Earth it wouldn’t even have been noticed.
The fixation of the first earthquake on Mars could create a new science branch – Mars seismology.
