Just a couple more overnight:

Wed, Sep 15 2010 0:36 am
Magnitude: 4.3

Wed, Sep 15 2010 2:42 am
Magnitude: 3.7

Both of them were 20 km south-west of Christchurch.

Someone on TV the other night said Christchurch had a big earthquake in 1929 - a precurser to the Hawke's Bay biggie two years later!
They said there was definitely a relationship between the two.
Ooooppps!
We live in Hawke's Bay now, although Wellington is our home town.
Wellington is situated on several fault lines and the scientists have said for years that Wellington is overdue for the Big One!
I've lived through several minor quakes - nothing like the people of Christchurch, but you never really get used to them.
