Wolfman - are you proposing that god was too stupid to design a planet with the benefits of tectonics without the dangers?
The solution is trivially simple, we discussed it on the tsuanmi thread.
From your link..
The main benefits of plate tectonics accumulate slowly and globally over the ages. In contrast, its local upheavals can produce regional catastrophes, as the recent Indian Ocean quake made clear
The advantages of plate tectonics would still happen if the plates glided under each other smoothly. Earthquakes and tsunamis happen because the process is badly designed and they get stuck, building up pressure for thousands of years before suddenly shifting and killing people.
If god designed that he is an idiot.
