<BR />"New Zealand/.../ experiences more than 14,000 earthquakes a year, of which only around 20 have a magnitude in excess of 5.0.

Yea the ones to beware of are those with no after-shocks.
It means you are sitting on a fault line.
A girlfriend told me that and the earth did move!
A fault line in Wellington branches right to the Beehive - Parliament to you!!!

"Do earthquakes occur in Britain?
YES, between 150 and 200 earthquakes are detected and located in the UK and surrounding waters, by the British Geological Survey annually."
There's a chart. I think "ML" may mean "as felt on the mainland" for earthquakes at sea. We get a magnitude five or up somewhere about every eight years, and, of course, a lot more smaller ones.
The last that I heard, which is a while ago, even during an earthquake, scientific measurement can't tell whether it is going to be a small one or a big one, until it is - although being in the U.K. is a clue. I suppose it depends on whether a small earthquake is enough to snap the resistance that's holding back the big one. Everything is under pressure and tension under our feet, like an elastic band cat's-cradle. Even here.
