Abstract
We estimate the apparent surface wave quality factor (Q-value) on Mars using seismic data from the Marsquake event S1222a recorded by the InSight lander. By applying spectral ratio methods adapted for Martian subsurface conditions, we derive Q estimates that constrain the attenuation structure of the Martian crust and upper mantle. Our analysis provides new constraints on the rheological properties of Mars interior and contributes to the growing database of Martian seismic observations essential for understanding planetary evolution.
