Could civilization exist with rapid tectonics?
I'm building a world that I would like to be quite realistic. One of the plot lines I've considered is plate tectonics that move at a rate of anywhere from 0.8 to 2.0 kilometers per year. This is in comparison to the Earth's rates of centimeters per year.
Would civilization be possible here? Obviously areas near fault zones would need constant maintenance to facilitate ground trade between them, and this would pose obvious dangers for any kind of mountainous peoples like dwarves or highlanders. But would it stop the rest of the world from developing life and civilization? What is the fastest tectonic drift that would be capable of supporting life, avoiding as much willingness to suspend rational thought as possible.
