It has been detected more than a simple seismic event, but a real seismic background that on Earth is originated by oceanic movements, major meteorological events and tidal interactions caused by the Moon.
In the case of Mars, however, given the absence of all these factors, Philippe Lognonné is convinced that all these continuous microseisms must necessarily come from within the planet!
Definitely an epoch-making event in the understanding of the internal nature of Mars, something that will necessarily make reconsider those who have always believed that Mars was a geologically dead planet 😉 😀
