One of the things about living in New Zealand in general and Napier in particular is the ever-present threat of earthquakes. I have experienced minor quakes but never anything too bad. They are, however, quite scary even at fairly low magnitude when things fall off bookcases! Last night my time and in the middle of rural France as I am the internet came into its own when I learned of the huge earthquake which had some six hours previously struch Christchurch on New Zealand's South Island. I am acquainted with a number of people in Christchurch and many friends have friends and family there - New Zealand is a 'small' place in that it's 4 million or so population is spread far and thin.
To give some idea of what Christchurch is going through the distribution of the last 30 earthquakes in NZ is shown on the following map. The four not concentrated over Christchurch happened on 1/2 September but the 26 over Christchurch have all been in the last 24 hours.
The following five happened within about an hour starting (bottom first) with the major 7.1 magnitude quake.
