NASA’s InSight lander has detected over 450 “marsquakes”


The “martemoti”, commonly known as “marsquake“, They are quite common on Mars but less intense than initially thought NASA. This is one of the discoveries he has found in recent months and which he has also published in articles published recently on the discoveries of InSight since he landed on Mars. Apparently, the tool Sismic Experiment for Interior Structure (SEIS) of InSight has recorded over 450 seismic signals or similar events since last year. These signals probably came from earthquakes and not simply from noises caused by environmental factors such as wind.

Mars: earthquakes are not real earthquakes and in addition they are relatively weak

NASA also revealed that the largest earthquake detected by SEIS was around magnitude 4.0. More benevolent than scientists expected. This power is not strong enough to get readings from the lower mantle and core of the planet that scientists hope to achieve, however. The main researcher of InSight, Bruce Banerdt, described these layers as “the most juicy parts of the apple“When it comes to knowing the internal structure of the planet, it considers them the most important parts. They can also help shed some light on how rocky planets are formed.

Earthquakes, however, they are not quite similar to earthquakes. Explained better, the planet has no tectonic plates and scientists believe that its rumble comes from volcanically active regions and internal cooling processes. All this causes the nucleus to contract and consequently create stress. Indeed, when InSight has detected the first potential earthquake, the director of NASA Planetary Science Division Lori Glaze he compared the event to an earthquake, which is generally weaker and much longer than a common earthquake.
