Despite the lack of large marsquakes, the researchers were able to estimate how thick Mars’ crust is. They predict it has three layers—but possibly two—that are between 12.4 and 23 miles thick, reports Nature. Mars’ crust is considerably thinner than that of Earth, which can be up to 25 miles thick—and that’s surprising, reports Science.

Lots of small “Marsquakes,” but nothing big. Max M4.5.

A techtonically silent world. Might explain the weak magnetic field which allowed solar winds to rip off its atmosphere long ago.
