英文摘要Of the marsquakes detected, super-high-frequency marsquakes are dominant (>60%) in number. However, their occurrence mechanism remains unclear. One possibility is local heat-induced ground motion. We model heat conduction under InSight based on measured subsurface thermal parameters and air temperature records, which provide insights into heat flow in the shallow Martian subsurface. Diurnal and seasonal variations of subsurface temperature and their rates of temperature change are analyzed. Diurnal temperature variations >1 K only occur within 25 cm of the surface. The highest rate of temperature change appears around sol 440 (in summer), which coincides closely with the season of the dominant number of super-high-frequency marsquakes observed. Thermal-mechanical finite-element simulations indicate that heat-induced ground motion is evidently stronger in the daytime than at night. These results indicate that super-high-frequency marsquakes are most likely induced by thermal stress in shallow rocks on the surface or partially buried within 10 cm depth.
