On Thursday, NASA announced that its InSight lander has detected two strong, clear quakes originating in a location of Mars called Cerberus Fossae. The interesting thing this that, it is the same region where the lander previously observed two sizeable quakes in 2019.
“The magnitude 3.3 and 3.1 temblors originated in a region called “Cerberus Fossae”, further supporting the idea that this location is seismically active,” says NASA
The Cerberus Fossae are a series of semi-parallel (1235 km across) cracks on Mars formed by faults that pulled the crust apart.
Landed in November 2018, the InSight lander has recorded over 500 quakes so far. It is a piece of strong evidence of some volcanic activity in the Martian underground. Perhaps, hot molten magma like we have inside the Earth.
“Over the course of the mission, we’ve seen two different types of marsquakes: one that is more ‘Moon-like’ and the other, more ‘Earth-like,’” said Taichi Kawamura of France’s Institut de Physique du Globe de Paris
DID YOU KNOW? – On Mars, the Sun appears about half the size as it does on Earth.
