Abstract Records of early geologic and thermal evolution after planetary accretion are rarely preserved on icy moons in the Solar System. Charon’s ~ 4.0 Ga surface age suggests the potential preservation of landforms induced from early orbital evolution. Here we show that despinning-induced stress inferred from compressive tectonic features explains latitudinal variations in the orientations and types of tectonic features in Charon’s northern highland, Oz Terra.

A 160-km-long seismic gap, which has not been ruptured over ~8000?year, was identified recently in North China. In this study, we use a dynamic source model and a newly available high-resolution 3-D velocity structure to simulate long period ground motion (up to 0.5?Hz) from possibly worst-case rupture scenarios of the seismic gap.
