Yes there's been a few aftershocks, the latest one i think is the 5.2 you mentioned that was only 6 miles down. One chap just finish building his brand new home got to live in it for 4 days before it fell to bits, house is now condemned. Plenty of stories like that one, then there's the water problem they had to ship drinking water from wellington by trucks and to finish it off they got looters!
A friend who's a builder by trade and out of work has loaded up his truck and headed off to Christchurch there be plenty of work for the next couple of years so tradesmen are needed. Total costs to rebuild the city is at 2 billion so far.
Christchurch was built on sand and is directly sitting on the EQ fault line.
