China News Service, April 2 According to the Russian Satellite Network, the National Aeronautics and Space Administration (NASA) released a message on April 1, local time, stating that the "Insight" probe detected two Martian earthquakes. It is called the Cerberus Fossae.
According to reports, "Insight" detected two strong and clear vibrations in the Kobelos trough zone in March, with magnitudes of 3.3 and 3.1 respectively.

"Insight" has also detected two strong earthquakes on Mars, with magnitudes of 3.5 and 3.6 respectively, and they are also located in the Kobelos trough.
Up to now, "Insight" has recorded more than 500 vibrations, but the signals of these four times are clear, which is the best record for exploring the interior of Mars.
Studying Martian earthquakes is a way for the InSight scientific team to seek a better understanding of the Martian mantle and core.
This planet does not have tectonic plates like the Earth, but it has volcanic active areas that can cause rumbles.
NASA stated: "The tremors recorded on March 7 and 18 (again) indicate that the Kobelos trough is a seismically active zone on Mars."
These two new Martian earthquakes were recorded nearly one Earth year (a Martian year is equivalent to two Earth years) after a series of similar strong earthquakes.
They all occur in the summer north of Mars.
Scientists say it may be because the summer monsoon to the north of Mars has become smaller, thus ushering in the ideal time to "hear" Martian vibrations.
The "Insight" probe launched by NASA in May 2018 successfully landed in the Ehrlich Plain of Mars in November of the same year.
The detector carries scientific instruments such as seismometers and heat flow probes.
