Tectonic Effects of Climate Change on Venus

Venusian plains regions are globally crossed by closely spaced small-strain deformation features such as polygonal and gridded terrains, and wrinkle ridges. The observation that the spacing of these small-strain features is relatively globally uniform suggests that a global scale process is repsonsible for their formation.

Moonquakes and lunar tectonism.

Review of the major discoveries that have resulted to date from the analysis of seismic data from a network of geophysical stations on the moon. It is found that lunar seismic signals differ greatly from typical terrestrial seismic signals; the moon possesses a crust and a mantle, at least in the region of the Apollo 12 and 14 stations; natural lunar events detected by the Apollo seismic network are moonquakes and meteoroid impacts; and in addition to the repeating moonquakes, moonquake 'swarms' have been discovered.
