I'm a geologist. 
There's no "serious" geology going on between Severian's time and ours. South America seems to be basically the same as now. So there are no substantial destruction of human structures by subduction, that become part of the mantle and then eventually become part of the crust again during orogenesis. Orogenesis makes itself felt on the order of the millions of years, or hundreds of thousands of years, although its not so linear as that.
