Abstract

Analyzing seismic waveforms recorded by the InSight mission seismometer, we discovered and documented 47 marsquakes in the Cerberus Fossae region of Mars. Their repetitive nature at all times of the Martian day tells a story of their likely volcanic origin and of a mobile Martian mantle. Mars harbours a liquid core, and it remains to be understood why the Martian geodynamic field ceased to exist.
