God and Subduction

The 8.9 earthquake rocking Japan this last week got me to thinking about "God's Plan" for mankind, as laid out in the Bible.  There is no mention made in the Bible, that I can find, of plate tectonics, subduction zones, and of volcanoes. 

Was plate tectonics necessary?  Was the shifting of continental plates part of His plan or an oversight, or a result of some other plan?  This is a question I'd like to see Bible literalists answer in detail.
