It was brilliant! I was sitting on the floor in the lounge (our furniture has still not arrived) and I thought someone was driving a bulldozer in the back garden and making the wall shake - then I thought it must be a very large underground train. Then I remembered we weren't in Brussels anymore and realised it must be an earthquake. The girls unbelievably failed to notice anything as they were to engrossed in Barbie singing on the TV.
It occurred at 5.16pm and was magnitude 4.1 - so not that big but still noticeable. Apparently there are 15000 earthquakes in New Zealand each year but only 250 are big enough to be felt. So I am looking forward to the next one - as long as its not larger than magnitude 6!
