Interesting webpage - the earthquake down south uplifted a 'wall' and a 
reef.
Pictures show some - but look at the video below the pictures for a tour 
and talk.
The Man is a Geologist discussing the block move.  But the movie goes on 
a helicopter
ride over the reef - some closeups.  Might be ripe for some shelling.

This was a 'thrust block' - one that moves up and across at the same 
time.  Some move
up and some move down.
