That was pretty weird, Mark.
BTW, it was centred way south of here, almost at the southern tip of the South Island.
From the accounts I've heard of the quake, it lasted for about 2 minutes.
I was driving home at the time, I thought something was either wrong with my vehicle or my eye-sight.
I stopped on the side of the road and the ground was still shaking.
Good to see no real damage/ injuries occured, because of the quake.
I would like to think that this is a bit of a wake-up call
to some of the authorites here, we are way overdue for a decent earth-quake, this place (NZ) is like a ticking time-bomb.
