The Planets around Tau Ceti may be fairly volcanic

[stevebowers]

The plate tectonics are interesting on Nova Terra; currently this world has a single continent, so it is in a 'Pangaea' phase. There is no real indication of the rate of plate tectonics on this world, except for the fact that the interior is pretty much one large mountain range- a 'super-Himalayas' that covers most of the continent. That suggests to me that the rate of tectonics is fairly high.

Note, however, that the Himalayas on Earth do not include any active volcanoes- perhaps the main sites of volcanic activity on Nova Terra are in the oceans, or possibly on the plates on the fringe of the continent.
