Today I was aware of an earthquake for the second time in a month.  I was sat at home reading to Anita when the whole house started shaking, rattling the plates and causing the lights to sway.  It went on for a few seconds, died down and then intensified again.  Remembering a website I had been shown, I went online and visited to find out the epicentre and magnitude, and was fascinated too see how widely felt the quake was- pretty well every recording site on North Island and many on South Island were recording tremors of MM4 and above, and even as I sat looking at their site seismic activity was being recorded.  Sliding the time bar backwards showed the spread of the shock, and after a short while I could look the quake up-

Down here it measured 4.0 on the richter scale, a magnitude that would make headline news in the UK.  Here, it barely warranted a mention in the Dominion Post.  At the epicentre it had a magnitude of 5.1.
