The thing that worries me is that they are still saying a mag 6 is "not unlikely" within the week. After being woken up about 4 times last night with mag 4.0 through to 5.2 (twice) and then pretty well quiet for 11 hours it's starting to get a bit edgy here - Is the next one the mag 6 or is that going to happen after dark (again) which just makes it all the more exciting. Especially if the power goes off as well. Otherwise, things have been quiet here all day. Work is still closed pending a building inspection so I'm at home today. I notice there have been a couple of shocks in the Hawke Bay area so if things are heading North you may get your own live experience yet Russell!
