These findings could help scientists better understand the formation and evolution of the Red Planet.
The findings reveal details about the Red Planet's crust and shed light on its thermal history. The Marsquake, estimated to have a magnitude of 4.6, presented a unique opportunity for scientists to gather seismic observations and analyze the surface waves that traveled throughout the planet.
Notably, the crust is thinnest at the Isidis impact basin, measuring approximately 10 kilometers , while it reaches its greatest thickness in the Tharsis province at around 90 kilometers .In comparison, the Earth's crust has an average thickness of 21 to 27 kilometers , while the lunar crust is between 34 and 43 kilometers thick, as determined by the Apollo mission seismometers.
Kim adds, "We were fortunate to observe this quake. On Earth, we would have difficulty determining the thickness of the Earth's crust using the same magnitude of quake that occurred on Mars."One intriguing aspect of this research is the difference observed between the northern and southern hemispheres of Mars. This contrast, known as the Martian dichotomy, has long been observed but remained poorly understood.
