There was a giant quake on Mars: it's as powerful as all the others put together

A new study shows that a huge quake was at least 5 times more powerful than the previous record holder.

An international team of scientists has published a new study claiming that the record-breaking quake that hit Mars earlier this year was as strong as all the others combined, writes ScienceAlert.

Back in May of this year, as Focus already wrote, the InSight lander has recorded record tremors on Mars. Now scientists have presented a new detailed analysis of this large-scale quake. Scientists don't yet know what caused it, but it certainly was unusual.

According to scientists, it was not only the most powerful quake known on Mars, but it was also the longest, because it lasted as long as 10 hours.

According to John Clinton of the Swiss Federal Institute of Technology, the amount of energy that was released during this giant quake is equivalent to the combined energy of all other quakes known to scientists. The researchers concluded that this quake was a force of 4.7.

Although a 9.5 magnitude earthquake has already been recorded on Earth, for Mars, which was considered a seismically dead planet, this is a huge indicator.

Now scientists are already sure that seismic activity continues on Mars. As Focus already wrote, recently scientists have found a special structure on this planet under the surface, which can explain the recent marsquakes.

But the search for seismic activity on Mars is not the only reason why scientists are actively studying aftershocks. The way seismic waves propagate through a planet's surface can help detect density changes in its interior. That is, with the help of these waves, you can recreate the internal structure of Mars.

“For the first time, we were able to identify surface seismic waves that moved along the crust and upper mantle of Mars and they passed through the entire planet,” says Clinton.

Scientists have not yet determined the exact source that caused the giant quake, but they are sure that some hidden structure under the crust of Mars is precisely responsible for this.

It is known that everything Marsquakes usually have either high or low frequency shocks. But the most powerful quake combined both frequency ranges, and scientists do not yet know why this happened.

Scientists believe that it is necessary to change the approach to the analysis of such quakes, which still hide many secrets.
